Practice Crit. This was going to be a shakeout ride for the weekend crit, but on the second lap I hit a pothole and had a blowout. Spare had a cut in it, so I was done. Wasn't paying attention and threw a pretty epic temper tantrum, to which about 30 warehouse workers who just left their building cheered me on.
On the plus side, I'm finally starting to feel comfortable in a pack. I know that's second nature for some guys but I've always had to work my way into it after a long layoff (and this one was 2 years).
