Rare opportunity to take the bike in and ride after work. Started from the park at the foot of the Big Bridge and did that four mile climb up the W&OD. Must be in decent shape, finally, because it wasn't difficult (Narrator: Let's be real, it's railroad grade, so 1.5 to 2 percent. Any old man can climb THAT. Foolishly decided that instead of riding down the Georgetown main drag, would do the tunnel under the canal west of the university. Well that turned into riding on the extremely narrow sidewalk and dodging irate college students before reaching the tunnel, which was VERY dark and VERY wet this time. The ride through DC proper was ... unfulfiling. Just couldn't get into it and quickly tired of having head on a swivel. Stopped at L'Enfant Plaza to put out a footfire -- air temp was in the 90s! -- and was glad to be back on that bumpy old Mt Vernon trail and away from drivers, though Virginia has done some work to shave off many of the bumps (pushed up by tree roots). It's much less bumpy though hardly smooth. Ended up appropriately tired with most of the contact points feeling ok; little stiff after the 45-minute drive home; still working on posture and sore neck. Truth is there should be some work to strengthen the core to allow bending over without needing support from arms.
