I am a wimp when it comes to getting going on a ascent, even at stops with a headwind.
Last week I had the dumbest of accidents though. My foot slid off my spin bike and I skinned/bruised my shin.

Yesterday I rode a solo 53 mile overnighter to a small town and biked back today after picking up a tractor seal for DH. I'm was very tuckered out when I got home.
Where do some cyclist get energy to go super long miles a day? I'll guess I'll just blame it on my age.
