53 yo Athena (clyde class) and my commute has varied 18-35 miles r/t depending on full/partial commute, office location. I've been commuting a year. I started for cross-training fitness and stress-relief. I enjoy weekend club rides for social reasons and to try out new routes as well as for the exercise. I ride about 300 miles/month; the commutes have some hills that wear me out (11% grade on a few) and TX heat also takes its toll hence need for many workdays to sleep in and recover. I also do some swimming and swim in a local Masters meet every year or so.

Surprisingly I am the only bike commuter at my current two 10-story office tower complex. Some of my co-workers used to ride quite well including some racing (not just charity rides) so there are people here who could commute. I've tried to encourage them but I suppose I'll just remain the oddball instead of setting a trend.

Beware of some of the older cyclists. Some of them have decades of cycling in those legs. Looks can be deceptive. Unfortunately I'm not one of them.
