I'm coming the other way -- I'm a runner just discovering cycling. Cycling hurts! There's constant quadricep pressure, glutes are worked differently, and the posture is taking some getting used to. Riding makes me appreciate running! But I get to see more of the scenery, and it gets me to campus.

Also, congrats on the discipline to pace yourself. It's especially easy for cyclists to want to shoot out fast, especially if they run the route they cycle. It's really motivating to see the seconds come off your mile times the first few weeks, and that only happens by staying healthy and doing the distance.

Wish you were in Austin starting in January; I'd get you to take Triathlon Swim with me for Spring semester and we could share the SAME misery.
