Cold but no wind today. Left late and caught merged with another rider where the 4 mile run trail and mount vernon meet, at the airport. I followed him until we caught another rider. I was the last in a 3 bike train for a mile or so until I felt warm and passed them at the rugby fields. They tried to keep up for a while but I stepped on it and dropped them. Once we got into DC one of the guys caught up at a light, we rode up 15th before he turned on Independance Ave. The fast pace really warmed me up and I arrived at work with my goatee soaked with sweat, it was a great way to fend off the cold. I realized that the number of cyclists I see increases exponentially the later I leave (duh), I'm usually on the road by 5:30/5:45 but enjoy seeing other riders when I leave late.
