Jumped into my first crit in 2019 figuring that if I was averaging 21.5mph solo on the road for longer distances, crit was 20 miles while I ride 25-30 or more, I'd be able to hang with the pack even if it was another 1mph faster. I couldn't hang with the pack and was lapped 6 times. Someone posted the race on youtube with their garmin synced to their camera to show speeds and such and they were doing 24mph through the sweeps and faster on the straights. I'd only managed 2 laps, each lap was .5 miles, before being dropped. Did the same race 3 weeks later, knee was better healed from a surgery I'd had 3 weeks before the first race, and managed to only get lapped 5 times. Seems like insane speed for what was a 4/5 race and seemed faster then what I remembered when I was in my 20s but I only raced road, cross and mtb and stayed away from the curcuit and crit races so maybe they were cray then too.
