It seems like everyone is different, every year. I've gotten them once before, but usually I'm fine. Nat gets them every year, but not this year. IDK, I just live here.
On Sunday after the Saturday rain, it was bad. I felt strong for like 20 minutes, and felt like I was going to end the ride with 2 KoPs*. By the end of the 2:20 ride I felt like I was riding in PB pavement. I was thinking about posting a YouTube video of one of those 1960's rockets that fly off into space then blow up. That's what Sunday felt like. About 1:20 in, the ride went to hell.
I spent a full day in Camden-Philly where there are not a shit-ton of trees. I may have just detoxed myself for 24 hours or so and I feel better because of it. It is what it is, at least I know it's there.
