although I have a host of excuses ready to explain it. My ride today was hot, it was windy (a bit), I haven't ridden in two months as I recover from ankle surgery etc. Not my fault!
21 miles was about the outer limit today though, and my HR was sky high compared to what I would have expected for such a non-aggressive ride. I did pass an old man on an electric assist bike... twice... so there's that.
I'd post a screen shot of my power curve today vs. my maximal power for 2013 but it's depressing, so I'll hold off on that.
