Holy smokes.

Did my first N2 group ride with my club since - oh, maybe October.
Got dropped about a half dozen times. Thankfully we had some re-group spots.
I've been doing a fair bit of riding - but slow commutes or slow rides with one or two friends. This was my first hard effort in a group in a long time, and wow. My legs felt it. Ice bath when I got home felt great.

57 rolling miles at 17.1 mph. Totally spent.
