I did take the gravel bike out yesterday, post Christmas indulgence guilt ride.
A mile up the road to the local MTB tracks in the woods, where I went up and down a hill several times. In my running days it would have been called "hill reps" but that sounds a bit grand these days, "survival reps" would be more like it. The times only changed by a few seconds so I must have been pretty steady.
Total ride was 15.8 miles and 2300ft
