4/4 19/21. Did my February Century yesterday. I felt like Death this morning too...Really tired legs trying to pedal into a 15 mph headwind up a slight incline....ick. For extra fun, I think my derailleur cable stretched, causing my chain to start skipping around....double ick.
I will adjust the cable tension before leaving for home today. Then its 2 days of no cycling due to work travel.
