thats great to hear, i'm a runner and I just bought a road bike to add some cross training this summer for the added aerobic benefit. i hope i have similar results to yours.
Do you still focus more on running? If so, how much do you bike in addition to running?
I don't think I will be able to bike a whole lot this summer, as I will be running 70-90 miles a week, but I'll try for a few good rides a week.
