In my first 2 C crits, the breakaway was successful. I was told that breakaways are rarely successful in C level crits. Like on the order of 5% chance.
Team tactics were in full display this past crit. Breakaway of 6, 3 on the same team. Then something like 10 teammates (of the 3) in the pack, blocking, and chasing down people trying to bridge.
As long as there is going to be one team with 13 teammates, and then a weaker team with 4 teammates, and then everyone else is basically a one-off guy--I think you have to be in the break or you're done.
It's not a great situation for a sprinter who wants a pack finish.
