12-13 minute miles bad? I must be bottom of the barrel then. When I was in high school, I think I did my required mile runs in like 16 minutes (yes, I walked a lot). To this day, I absolutely ABHOR running
Which is too bad for me, I guess, because I was a competitive swimmer in high school. Swimming's nicer than running, in my opinion. Oh well, no triathlons for me...
That commute sounds scary. Are there any alternate routes you can take? Oh, and the more you ride your bike (especially if it fits you well) the more enjoyment you'll get out of it. I like riding on the roads myself because of the adrenaline rush in dealing with automotive traffic
