I've not sat on a road bike in 16 years. This morning I took a trek through Prague and through to the Czech countryside at dawn. I rode South from the Charles bridge, past the yacht club and down to the golf club. Great! Nothing hurts. Then I discovered my limits by hanging a left and going up an extended 1 in 7 climb that kicked my ass. I had to stop three times on the hill, no less. Pitiful. I've got a lot of work to do. Last time I was riding a road bike I was a teenager, 40 lbs lighter. That's like hauling an extra bike and a half around. ~19km with my detour. Map it.
