I was in a two-man chase in the 3/4s; two guys were up the road, out of sight, the main field somewhere behind, also out of sight. This other guy and I were just trading pulls, for like four laps. Then, four dudes come bridging up from behind. I asked who they were. Three of them were yer 5 break, and the fourth was a 4. I told them mixing fields was a no-no and we established two little groups, each in a respective lane. We rode for a lap and a half like that and I never saw your pace car.
What galled me was, that 4 who bridged up beat me in the sprint. If he hadn't jumped on with the 5 break, who knows if he'd have been able to bridge solo, and I might have picked up a place. Hell, the entire race might have ended differently.
Whatever. It was a late-late-season race on a freezing cold morning. Some lessons learned for next time, I suppose.
