Put out a call welcoming folks to join me for a century as I prepare for a 300k next weekend. Four WCDev teammates (Krystal, Jenn, Chris T., Chris H), and four WCCC mates (Eric S., Phil L., Gilbert. T., and Bill H., who joined around mile 40) came through. Delighted at the turnout! It was smooth rolling, until Bill's front tire got slashed and needed a boot and a tube. In my haste, I discovered that fact after the tpu tube I gave him exploded. Got him rolling and made it to Prince Street Café, where I had some amazing vegan banana bread. Less than 20 minutes into the return ride, Bill flatted again. Then I double flatted. Then Bill flatted a third time. We finally got rolling, but Gilbert was hurting. I dropped back a few times to drag him up. But it was getting late, and Eric had a conference call he needed to make. So we split the group. Phil and I stayed with Gilbert while the others went ahead. From there, it was steady work. My patch repair started leaking by Coatesville, and in Modena Gilbert gave me a 26c tube I got to work in a 38c tire. I'm going tubeless for the 300k, but I think I need rim strips if and when I run tube again. Otherwise, the new bike is dialed and I feel like I can get it done!
