Raced saturday. Started a breakaway 1.5hrs in, 4 bridged up after a few minutes. Got completely raked over the coals until we were caught like 15 minutes later - simply couldn't recover from my initial jump and solo effort and was dying doing the equivalent of low sweet spot. I felt pretty bad for ruining the rhythm, I definitely prevented any sort of cohesion from forming.
Post mortem assessment - I am thinking it's a combo of not sitting out of the rotation for long enough to regain my composure and needing more race miles. I've done very little work above vo2 this year so far, so it makes sense that those sorts of efforts are difficult for me to recover from, and that should develop naturally the more racing I get in. I'm not really sure what I'd aim for during training rides to train this particular weakness so I suppose I will experiment a bit. On the plus side, this means I'm fit enough to instigate breakaways in p/1/2 fields, so I can't be all that far off.
