I'll start with the preface that everybody has to learn for themselves, and Cat 5 races are for learning, but some things crack me up:
1)there's hardly a single corner in a crit that someone doesn't yell inside (see earlier thread.)
2) Why would anyone sit in on a hill, while the pack climbs it at a moderate pace, only to attack into a headwind on the flat just after the climb. Yesterdays race it was the same pattern for 3 laps, climb the hill at a moderate pace, then attacks break lose just after the top into the wind.
3) Yelling "get out of the way" is not going to open up a line for you in a field sprint. On yesterday's up hill finish I was pinned on the far edge of the road when the guy infront ran out of gas,and there was no room to go around. Only thing to do was wait until an opening developed The guy behind me caught in the same circumstance was yelling at me to get out of the way, like he thought I had some obligation to pull off the road and yield to him.
(by the way I'm not complaining about getting boxed in, you pick your wheel and your line and you take your chances. Besides I wasn't going to win a hill top finish anyway.)
To the extent there's any theme here, announcing your presence and intentions, a la points 1 and 3 is going to shut down holes, not open them.
