I've done quite a few ~10 mile rides. Yesterday, I decided to see what I could manage. I rode a little over 26 miles. Near the end, my neck, back, and arms were all pretty sore. About two hours later, I had a nasty headache that lasted till mid morning the next day. Most of the muscle pain in my arms and legs went away just an hour or so after getting off the bike. The odd thing is that almost 24 hours after getting off the bike, my legs started aching, followed by my arms. Compared to the aches I had right after the ride, this is deeper and less sharp. While it started in my legs, it's now stronger in my arms than in my legs. Has anyone else had muscle pain go away, only to come back so long after a ride? I suppressed an urge to go for a twenty minute spin around the block. Would that have helped? Maybe a specific stretching or cool-off regimen?
