Challenge Accepted! and maybe even showed a good time? Kwang is doing a lot more than I am, and I'm claiming to be in good shape? Nope! It's funny...big difference between running and cycling. Runners, they get started easy: "Wanna go run?" "Sure, let's go!" Gone...Cyclists: "Wanna go ride?" "Sure, let me find my helmet and gloves, check my air, fill up my water, then we'll load up the car and drive to where we can ride." Cyclists can coast downhill after chugging up some crazy incline...runners gotta pound the pavement or gravel up AND down. Runners take forever to get anywhere...3-4 hours for a marathon? 26.2 miles??? PLEASE! Cyclists do 26.2 miles in a couple hours TOPS...it's a CENTURY that's a cyclist's challenge! Ok, maybe a METRIC century (100km - 62mi). Runners got ultra-marathons, cyclists got randonneuring. Do either one long enough, you're going to get in better shape!
