I think that's great advice. I went out a couple of days ago when conditions were pretty good and I took your advice and rather than slowing down and being like "OH GOD! A LUMP" I tried said to myself "let your legs do their thing" and it totally worked!
I always ride with my boyfriend who is better than me even though we started at the same time... maybe not better but more fearless.
Today I had less luck but it was icy out...
