The forecast... downpour rain from 7 am to noon. Race time: 8:30am.
We took the chance and drove to Zenitsubo to check in. Got to the top of the mountain and was pleasantly surprised to see a good number of cars at the top already. By the time we got to the top it was still pretty dark, but it was apparent we were in the clouds which would bring us the dreaded rain later that day.
Side note: One of the things bad about the rain on these roads to the top of Zenitsubo (pronounced Zen-eat-si-bow) is the metal rain grates that run across the width of the road in all the wrong places. They're placed particularly on corners for drainage. They are treacherous to go over in a turn for a bike with 23mm wide wheels.
Checked in and found out I was guaranteed to be in the top 10 of my group. I was entered in the "Champions" group which only said, I'm a pretty gosh darn good rider in comparison and I don't have to fight up the mountain with the masses. There were seven of us in that group and our start time would be 10:30am (now three hours away).
While waiting for one of my local ride partners, another Japanese man approached me and asked if I was champion class. I gave an affirmative reply. We talked real quick about times and I was humbled when he said last year he finished in just over 27 minutes. My goal for today was 30 minutes and my personal best so far had been 32 minutes.
We got out to the car and prepared to wait, but it wasn't long after that when they told us the race had been canceled because they were concerned of the danger on slick roads and the oncoming rain. We packed the car back up and headed on home.
I waited around the house for about an hour, staring at the weather radar and mulling over doing the hill climb anyway. By 9:30am I was out the door doing a nice easy spin for the 25 minutes it would take me to get to the base of the climb. It had yet to do anything more than spit a few drizzling rain drops at the ground so up I went.
The first 10 minutes went faster than I'd expected. The first 10 minutes includes about 2 minutes of up/down rolling terrain, more down than up. I certainly lost some time here having to be extremely careful around the corners and on the wet grates. I rode the brakes most of the way through this downhill section. But, when I got to the base of the long part of the climb, I was ahead of my pacing time by about a minute.
I had chosen to stick with the 12x23 cassette in the rear. This is an extremely high gear for this climb requiring a lot of time in the low 50's for cadence. If I were to race this again, I'd probably switch the bike over to a 9 speed so I could get the back gears down to around a 29T cog. I could spin a lot faster (up to 15 rpms faster) and sit down for a lot more of it.
On paper, the last three stretches were: 18 minutes @ 340 watts, 50 seconds @ 430, 2 minutes @ 370. I finished this stretch in 20 minutes 46 seconds in actuality. The last 5 minutes was pretty drastically different than the plan though. That 50 seconds at 430w was just not happening.
End time was 29 min 56 sec. I squeezed in under the wire for my goal, but I squeezed in nonetheless. I'll add this to my workout routes once every other week to work on pacing specifically up the mountain. Next fall when this race happens again, I expect to be faster because I expect to have trained more. I also expect to be faster as I learn how to pace Zenitsubo for the best times in the best places.
