Got an early one in today, 5:30 in the morning. I alternated between hills and flats for the 27 mile ride. Finished up with an 18.1 mph pace and 1300 ft. Early summer mornings are my favorite time to ride. Nothing beats great temperature and low traffic.
I watched the end of Le Alp d'Huez stage then went out and did 3,000 feet of climbing over 6% which is my point where rises become climbs. The steepest section was 12% and the only stop I made in the first 32 miles was to let my heart rate go down (50 meters from the top of one mile of 9% average climb and after a quarter mile which included 12%) and drink some water. Since I don't have any balance anymore I can't drink while riding unless conditions are perfect.
Restarting after the second stop I missed the pedal and flopped down into the middle of the road just as Joe Racer in his Porche came around the blind turn at 60 (in 25 mph zone) Obviously he missed me cussing me out the entire time. Try standing up from laying flat on the ground some time when you don't have any balance.
I stopped at a Crepe place at 32 miles and had an ice tea and a savory crepe with tomatoes and cheese and something green inside that was probably spinach. I was recovered enough that I rode over another 500 foot climb on the way home. It was only 7% though so the only good thing about it was the mile long descent on the other side.
I've converted to tubeless 25 mm Michelin Pro4 Endurance tires and am now confident enough in them that I only carry a tool and CO2 inflator with me in case I hit something large enough to give a tubeless a flat. But these tires ride SOOOOOO good as tubeless that it really improves the ride of the Pinarello Stelvio. And the 28 mm tires I put on the Time VX spectacularly improved the ride of that bike. It is now the best riding bike I have and I'd keep it if I wasn't permanently off of carbon fiber.
I'm almost relaxed on the Pinarello descending at 45 mph. If California roads weren't so bad I would be. The route I was on has been turned into a short-cut by Box-Vans during commute hours despite the sharp turns and limited speed limit which is universally ignored. This causes dips in the road where it doesn't cause cracking of the surface. You can dodge the cracks because you can see them but at 45 mph you cannot see the dips some of which are almost bad enough to throw you off. So I'm stuck trying to memorize where they are and the medication I'm taking screws up my memory.
Unlike young people my average speed was 10 1/4 mph but with all of that hard climbing I figure that's good enough.
Now today I'm so sore that I'm really glad tomorrow's ride is with the old farts and I can use it as a recovery ride.
