I started running back around the first of the year, and only got back into cycling around April/May of this year. This year's Ride of Silence in May was sort of my "gauge" to see if I had improved over the same ride last year. I was a little bit better, but not much. Though I'm still very slow running, also, and currently only run about 30 minutes continuous at a time (compared to 30-45 second intervals when I started).

Now a seasoned runner, maybe. But for me I don't think it really made much difference. However I'm still running and also cycling, and I think the two have been helping improve one another in terms of my lung capacity and so forth.
