Warm temps this morning, but that generally means I'll have a headwind, so it was a tough ride to work despite temps about 50 F. My legs are also getting tired from riding a lot this week. Another bike commuter caught up with me at the last traffic light before my office and we chatted briefly, and I realized after talking that he uses the same website for tracking rides, so I sent him a message after I got in my office. Ironically, I got a flat tire while we were chatting and had to walk my bike the last 25 feet to the bike rack.
