Hi guys, my tracks race night works on
10-15min open track for warm up
4 Races

During the warmup, I don't go out too quick, I start out very steady yet I feel really bad cramps in my glutes and hamstrings. Is this due to flexibility? Mine absolutely sucks, I can touch about halfway down my shin before I start to break a sweat!
Or, could it be because I don't put a 'warmup' gear on? I warmup at a lower cadence and just leave the race/sprint chainring/cog on.

During the first event (if it's a long one) I'll start to feel good and then feel like I can contend for placement, so the 'issue' does resolve itself with more time. Do I just need to warmup for longer? (And therefore take my own rollers/turbo).

Thanks for the input!
