Weather update

It didn’t rain after all

The anticipated rain which delayed the start of my ride yesterday never materialized after all. But after the ride was over, the wind picked up considerably. We closed the windows of our flat around dinnertime.

This morning as I departed for the office I was greeted by a visual reminder of last night’s wind.

Here comes the sun

The other amusing thing about yesterday’s weather was the rapid change in cloud cover. While I was preparing for the ride, it was completely overcast. As I was riding light and only going to be out a short time, I didn’t use any sunblock.

Then, the moment I wheeled my bike out of the parking lot, the clouds cleared up and the sun shown down brightly. I was glad for my UV mask (for a change). But when I cleaned up after the ride, I discovered a couple of spots of sunburn on my wrists where the sleeves of my T-shirt didn’t quite reach the gloves.

There’s a similar very narrow stripe of sunburn on the bridge of my nose, from the tiny gap between the mask and the sunglasses.

One before the rain

I’d planned to cycle at least 100km today, and perhaps go as far as 140. I was starting to get ready at 8 a.m. when Nana said, “You’re not going riding, are you? It’s going to rain.”

Oh.

Well, I have plenty to do around the house. I relaxed for a bit and then started thinking about the housework.

Then around 10 a.m., Nana said, “According to Yahoo, it won’t rain until late afternoon or this evening.”

Oh.

I decided to make it a short ride, and started getting ready. I chose Haneda for the destination, and the decided to travel light. No GoPro. Get out the door.

Well, maybe not that light …

After putting my smartphone and wallet in the cockpit bag and putting the water bottles in their cages, etc., I started wheeling Kuroko towards the elevators. And then I realized I’d forgotten the Garmin. That’s OK, I don’t need help with the navigation, and I can use the Strava app on my phone to track the ride.

The ride to the river was uneventful except for one driver on a one-way street who was a bit upset that I wouldn’t just pull over and let him pass. I could hear him revving his engine behind me, and then he honked. I didn’t let him bother me. Not long after his honking, we got into pedestrian traffic and parked vehicles on the road, and I was able to race ahead while Mr. Horny was stuck.

On the river, there was no wind at first and I made good time heading downstream. There were a lot of pedestrians out, and the little leaguers and tennis players on their bikes — returning home after the game or match — were riding three or four abreast and typically not looking where they were going. A couple of them got shirty when I called out for them to watch out.

After the first brief break for water, with about 10km to go to Haneda, the wind started picking up. It wasn’t bothering me for the most part: a crosswind that was probably coming more from behind than ahead. I was keeping up a good pace and watching out for children on scooters.

Bit of a breeze

By the time I got to Haneda, the wind was blowing pretty strongly…

What wind?

Lunch spot in the shade

I made a quick lunch of two onigiri (store-bought; Nana had not made any rice) and was soon on my way back home. Heading upstream, at times I was fighting the crosswind and at times it was helping me along. I felt good and knew I was making pretty good time, so I was keeping my breaks short. I was thinking of an alternate route home: there’s another bridge just about 1km beyond Futagobashi that leads to a 16% climb out of the valley, which is good practice for me. (My usual climb is 4-6%.)

Reconsider that decision

I’d pumped my tires up to about 45psi before departing, compared to my usual 50-60psi. The ride was noticeably more comfortable — of course the tires can’t do a thing about the big breaks in the pavement, but they were smoothing over the smaller stuff. More importantly, there was no feeling that the tires were underinflated or getting squirmy under my weight.

That’s all to the good. The bad came about 1km before Futagobashi (the bridge where I usually cross the Tamagawa on my way home). Suddenly Kuroko was making a grinding, crunching noise. I immediately eased up my pace, and then went through my usual checklist. No noise when I wasn’t pedaling. The noise seemed to coincide with the cadence of my pedaling, not anything else. The noise was present whether I used the larger or smaller chainring.

Things were pointing to the bottom bracket bearings or a loose crank. Less likely to be mangled chainring teeth as the noise was occurring on both chainrings. Kuroko has had a bearing habit, when she was sporting the ill-advised FSA crankset. Since I switched to the Sugino (and the bearing size Kuroko had been designed for) things have been smooth sailing. Has Kuroko reverted to her old ways?

So, a change of plans: rather than challenge that 16% grade, I reverted to my usual route home. After crossing the Tamagawa and just before starting the climb, I stopped and gave the crankset a good manual check, pulling up and pushing down on each pedal. No sign of looseness that I could detect. I shrugged and mounted up again, and climbed the hill without a further sound (well, none from Kuroko).

At the top of the hill I took a break in my usual spot and messaged Nana that I would be home within an hour. I was still making good time, and if my little mechanical could hold its nose for a few minutes, I’d be home well before the time I’d given Nana.

The traffic was smoother on the way home, for the most part, and Kuroko was silent — for the most part. I could still hear a bit of ticking from time to time as I sped homewards, but nothing like the crunching I’d heard along the Tamagawa cycling course.

I got home a full half-hour before I’d predicted, and brought Kuroko up to the Workshop in the Sky. I’m going to have a look at everything when I get a chance: chain wear, cleaning and lube (if not worn), bearing wear, crankset tightness, chainring and sprocket tooth wear, even the saddle (which has recently developed a slight rocking). In the meantime, I can ride Dionysus to the office and back.

Kawagoe windy and wet

I just rode to Kawagoe a couple of weeks ago, but when the weather turned unexpectedly sunny today, I couldn’t resist going again.

I’m getting quite familiar with the ride out Yamate Dori and Nakasendo to Arakawa. The signpost at the top of the levee is a regular landmark for me.

The course was flooded in places from yesterday’s rain. I started the ride at the mid-level all-weather landing (the red course) to avoid the water, but it was quite broken up. Even with my fat tires, some of the seams and gaps were a bit jarring.

By the time I ran out of red all-weather pavement and descended to the regular course, I was past most of the deep puddles. Even so, I took a moment to message Nana to apologize in advance for the wet, muddy laundry I’d be handing her when I got home.

The clear skies and stiff breeze following yesterday’s rain left some grand vistas for today’s ride.

The closer I got to Kawagoe, the stronger the headwind became. I’d dropped to my smaller chainring, into my climbing gears even though the going was flat. The headwind was strong enough it was pulling my mask down from my nose. Despite this, I felt stronger than I did two weeks ago and I continued pressing forward. I was also more confident of the route this time, having experienced it once already.

Chimes of the times

Pressing onwards against the wind, I made good time into Kawagoe. I didn’t walk around Koedo (except to get this photo), but just cycled up and down the length of it before heading for a convenience store and then a park for lunch. (Because we’d been expecting rain, Nana didn’t make any onigiri.) In the park I lucked out and got a picnic table all to myself. I felt the sun beating on my cheeks as I lowered my mask to eat a couple of tortillas. I watched a child playing with a kite as I ate. Other children sat nearby with their families on plastic tarps on the tree-shaded grass.

I washed down my lunch with some convenience store espresso, gathered up my rubbish and set off for home.

Wind at my back

On the way downriver, the wind was (mostly) at my back. I was amused to notch up a 12-minute 5km segment — implying an average of 25km/h — despite having stopped for traffic a couple of times and a photo once. The next 5km segment might have been 10 minutes (30km/h), but I had to wait more than a minute at a traffic light. I didn’t mind: I was making good time and having fun, and it was more pleasant to ride with a tailwind on the way home than to fight into a stiff breeze as I had on the way up.

I stopped where the course passed over a flood gate and ate a Snickers bar. Energy for the upcoming fight through traffic.

Fighting my way back to you

When I left the river course behind I headed back into traffic and also back into the wind. I’d given Nana an estimate of an hour to an hour and a half for my return, because I didn’t know how much wind I’d be facing. At times it was quite stiff! I had to be careful I wasn’t blown into the path of the fast-moving traffic just centimeters from my right elbow. (Shout out to the taxi driver and the driver of the red Volvo who didn’t make use of the entire open extra lane when passing me!)

The wind wasn’t constant: it was coming and going, and blowing in gusts. At times I was struggling to get to the top of the next climb, and at other times I was keeping up a very good pace. At traffic lights I had to sit up and stretch my shoulders, relaxing the muscles that were hunched against the headwind while I was riding.

I had no idea what kind of time I was making in the 13km from the river back to home. I’d hoped to improve on my time from two weeks ago (feeling quite a bit stronger overall), but with the wind in this final leg I thought I might be falling behind.

At the crossing for Shin Mejiro I checked the GPS: I had another 6km to go. Even fighting with the wind in the few remaining uphill sections, I’d be home soon. At the next light I caught up with a younger, more fit rider on an orange classic steel racing bike who’d passed me earlier. I kept up with him on the next rise as we both fought against the wind. And then we were at Nakano Sakue! From there it was downhill before turning off Yamate Dori onto a flat kilometer to the goal. As we descended, the other rider was content just to coast. I thought about passing him but finally just shrugged. I’d be home soon enough. I made my turn — at the wrong place. No worries, as I was already in my neighborhood. I ignored the GPS beeping and just followed the familiar streets. I checked the time as I stopped the GPS: a good 15 minutes earlier than the lower bound of the estimate I’d given Nana, and an improvement of 20 minutes over my previous ride on the same route.

I knew that I would now

I didn’t go far today, just the usual run down to Haneda and back. The weather was really nice, with bright, hazy skies and not much wind. With such nice weather on a weekend, though, there were a lot of careless people out on the Tamagawa cycling course. I had to stay alert.

I made the effort today to keep my mask on for most of the ride. This was more for the UV blocking than Covid protection. (It’s not really necessary to mask for that while riding as I don’t ride near other people.) I only had to lower it on occasion when my sunglasses would fog up, usually at a stop. On the other hand, it was only about 17C at most today. It will be a different proposition when it’s 30C this summer.

I was making good time today and felt strong — certainly better than I have since coming down with pneumonia last month. Even the few short climbs on the way home didn’t phase me. I did have to come to a screeching halt when passing through a small shopping area and a young boy biking in the opposite direction wasn’t watching where he was going. I shouted out to him and he looked round at the last second. He braked hard and just bumped into my front tire. I tried to smile and said, “Eyes front, fellah.” His father (who had already passed me safely) called out an apology. No harm done, I’m glad to report.

GPS record of cycle ride
I knew that I would now

I didn’t have any mechanical trouble during the ride. I’ve been fighting with the front tire since returning from Shimanami Kaido. I’ve replaced the valve but it continued to leak, so I added more rim tape around the valve, and now I can’t get the tire to reseat. Rather than fiddle with it further today, I just pumped up the tire on my spare front wheel — the one with the dynamo hub that I used for Lejog. I recently put a new tire on this, the same make as my usual tires but with a bit of a knobby tread. So with that on the front on the usual slick on the rear, I had a semi-mullet set-up.

The tire with the tread makes a bit more road noise than the slick. I’m sure it is fractionally less efficient, and ditto the dynamo hub, which is also a bit heavier (but wasn’t under load today). But apart from the additional noise — just scarcely enough to be noticeable, honestly — I didn’t notice much difference. The slick tends to hunt over lines in the pavement (particularly ones parallel to the direction of travel), while the tire with tread doesn’t. I think my strength and well-being today overshadowed any minute loss of performance this set-up entails.

I visited Kawagoe more than five years ago with Nana and her family. We went by train that time, and it took so long to get there I didn’t realize how close it was until I accompanied Fearless Leader Joe when he borrowed Dionysus for a stay in Saitama. I was very surprised to find after heading a few kilometers upstream on the Arakawa that we were passing into Kawagoe!

But, as they say, there’s Kawagoe and then there’s Kawagoe … We didn’t see any of Koedo (the Old Town) on that ride. And when FLJ subsequently had business dealings in Kawagoe, he didn’t even realize Koedo existed! But it all got me to thinking. In the intervening months I plotted a course that would take me from home to Futako Tamagawa, up the Tamagawa to Hamura, and then overland to Kawagoe (and of course passing through Koedo!) before returning down the Arakawa to home: a total of 125km.

Today I did something a bit less ambitious: from home, up the Arakawa to Kawagoe and back would be just 85km, and largely flat. I set off just before 9 a.m. after dealing with an unexpected mechanical, and was soon making good progress on Yamate Dori and Nakasendo Way towards the Arakawa.

Upon reaching the river I turned upstream, into uncharted territory for me. (When we delivered Dionysus in November, we’d crossed the Toda Bridge and continued on the opposite riverbank.) I’d plotted everything out on Google Maps and Street View (where available), but it wasn’t always clear what was a rideable path and what wasn’t.

Night and day

It was such a pleasure to be back on Kuroko after yesterday’s jaunt on Dionysus. The drop bars, the high-volume tires to soak up the bumps — a pillowy promenade after a rocky road.

That’s a path, according to Google

And after less than an hour’s riding along the river, following the Garmin and the other cyclists, I came to a section where the path was blocked off. I descended from the levee to the parallel street, as I’d seen a couple of other bikers do, and from there I kept looking for an opportunity to get back to the cycling course at the top of the levee. I was a bit premature — I ended up cycling a few hundred meters of gravel before giving up and returning to the street level!

And the route was complicated by road construction and detours. Thank goodness Japanese baton-waving construction workers don’t get bashful in the presence of foreigners and struggle to speak English. The fellow I encountered just called out, “Keep going that way until you get to the white sign, then turn right!” The directions were perfect.

In the end I joined up with paved cycle path atop the levee less than 1km before I was due to turn off and set across farmland towards Kawagoe proper. Unfortunately, Google Maps in this territory doesn’t have cycling directions, and the walking directions led me to a decidedly non-cycle friendly route down from the path. I made a mental note to look for an alternative on the way home.

Kawagoe

Once off the path, it was just a few kilometers through farmland before joining up with a main route into the city. Before I knew it, I was turning into Koedo and the Kurazukuri no Machinami — the warehouse district.

Lunch!

By the time I’d finished photographing Koedo, it was nearly noon. There are many restaurants and take-out counters in Koedo offering a variety of tantalizing Japanese dishes, but I was fully stocked with Nana’s world-famous onigiri. I quickly back-tracked to a sakura-adorned park near the Arakawa and gobbled down four at one go — surely a record for me!

The route home along the Arakawa was an easy one, particularly now that I knew which parts of the cycle path existed only in Google’s imagination. The road along the levee was quite narrow in bits, but I was soon back up on paved cycle course heaven! Unfortunately that only continued for a few hundred meters before it was back down into the streets and construction and detours, but this time I knew where I was going and when I would be back on the cycle course.

On the return I was fighting the wind a bit — either it was calm on my way upstream or I was unwittingly benefiting from a tailwind — but it didn’t hold me back much. It took just an hour and 17 minutes from the time I left the park to return to my favorite signpost marking the point where I leave the Arakawa cycling path for the welcoming arms of Tokyo city traffic.

Masked against the sun

I’d applied my regular sunblock on my face before leaving the house in the morning, but not the extra super stuff. I was expecting weather more or less like yesterday’s overcast skies, but it turned out to be quite a bit more sunny. Fortunately I was wearing my UV mask and pulled that up over my nose when the sun got strong (even when I wasn’t in the presence of others). Whenever I felt it was getting uncomfortable and wanted to pull it off, I reminded myself it’s not all that hot yet, and I need to get in the habit of wearing the mask even if it’s 30C.

Racing traffic towards home

I know the route from the river back home well, and I don’t let myself get excited about the traffic whizzing past my elbow. It’s a major artery the whole way, but there’s a good margin left for cyclists for the most part. I only had a couple of times going around a parked car, with my hand out to indicate I was coming over, where a driver didn’t feel he needed to give me room. It was on this same route back in November that Fearless Leader Joe put his hand out to indicate he was coming around a parked car only to touch the bumper of a car coming up fast behind him!

In the end I got home at 2:30, just five and a half hours after setting out, after telling Nana I’d be home about 5! I made good progress today, aided by the largely flat course.

Mechanical

Ah, what would a Guy Jean post be with a mechanical? Since my return from Shimanami Kaido, the front tire has been losing air slowly. I’d fill it up and leave it a day or two, and find it nearly flat.

This morning I figured I’d fill it up and it would be OK for the day’s ride. I was in for quite a surprise — I’d no sooner filled the tire than it began audibly leaking and visibly going soft. The reason was soon apparent as latex sealant sprouted around the valve.

That’ll be a leaky valve right there

I’d had the same issue with the rear tire just a couple of weeks before, and had quickly fixed it by replacing the valve with a high-quality unit from Schwalbe. In that case, the leak had been from the valve core itself, while this time it was clearly from the base, where the valve emerges from the rim.

I quickly thought: I could futz around with the valve as it is and try to get the base to seal up again. Or I could simply replace it — I had another Schwalbe on hand. I immediately decided for the replacement.

The new valve held the pressure immediately. After inflating the tire again (with a number of satisfactory popping noises as the tire seated on the rim), I could still hear a bit of hissing, but not from the valve area. I swirled the tire around to get the sealant to the leaking area, and the sound soon stopped.

That’ll hold?

Unfortunately I proved to be a bit optimistic in my evaluation of the fix: I stopped a couple of times during the day’s ride to top up the pressure in the front. I’m happy to say though that we didn’t reach the extreme of having the tire roll off the rim and burp out all the sealant, as happened on the Arakawa back in November (albeit with a different set of tires).

The forecast is for rain tomorrow, and I’ve got Kuroko up in the Workshop in the Sky. I’ll get this leak sorted or know the reason why.

With a late start this morning and a longer ride planned for tomorrow, I was in the mood for a shorter ride today. Between my two typical short courses — Haneda and the Tokyo Landmarks — I chose the latter.

The skies were grey when I departed, with the forecast for more of the same all day. It may not be the most cheery weather, but it makes it less likely I’ll get a sunburn. For most of the day, my shades remained in my bag.

I hadn’t given Nana a clear answer yesterday on whether I’d be biking today, so she didn’t make any onigiri.

I’m not able to eff why I decided to ride Dionysus today. Kuroko should be fine to ride following the shifter cable replacement, and I’m planning on riding her tomorrow. But I made the right choice today. My pace was easygoing — not to say lackadaisical — and we had fun.

At Tokyo Big Sight I stopped to get lunch from a convenience store. Unfortunately it was 12:15 on a weekday, and the shop was packed with people. I had to wait for people to move to get what I was after, and then waited in quite a long queue to get to the register. Fortunately, the workers were fast and efficient, and I didn’t wait very long.

Hungry as I was, my eyes may have been bigger than my stomach. When I set out again after eating, I was feeling a bit leaden. Within a handful of kilometers the feeling passed. I still don’t feel as strong as normal, and I don’t know if that’s a lingering effect of pneumonia, or just the effect of having missed nearly a month of cycling. At any rate, I continued on at a comfortable pace.

Dionysus didn’t give any trouble. I raised the seat slightly at the beginning of the ride and that seems to have been a good choice. The main water bottle bracket — the one on the down tube — was a bit loose, but that was quickly remedied with the minitool. After about 50km my left wrist got tired. I was riding in traffic all day so I didn’t want to ride on the horns, which takes my hands away from the brake levers. So I just rested the wrist at every opportunity (such as the multitude of traffic lights).

Although the skies looked like rain all day, we didn’t have any — true to the forecast. When I got to Budokan I messaged Nana that I’d be home in about an hour. In the end I made it in half that.
