How long does it take you to "warm up"
I went on a 128 km ride on Sunday, and for the first 30-45 minutes I had aches and pains...until finally either I tuned them out or my body decided to warm up and forget about aches. If I had listened to the knee creaks, hamstring aches, butt pain in the first 30 minutes I would have turned around and gone home.
I imagine this isn't too unusual, right? I'm just turning 40.
