Do you guys always warm up before a race? I've a race coming up and would love to hear your pre-race strategies It usually take 15/20minutes for my muscles to feel ready to go...

What race?

For short runs (10k or less), you should be warmed up and ready to "sprint".

For the half and full, if you've got the energy reserves, run a few miles to loosen up.

For us folks here in the weeds, jog a little bit and use the first few miles as the warmup. I read somewhere recently (can't cite the source) that every run should be a negative split.

Oh, static stretching is a great way to pull muscles/run slower/ etc., etc. Every thing I've read about studies done on static stretching conclude that it reduces performance when you static stretch before you run. I know - everyone does it and everyone does it because everyone does it. Sure fire ways to tell who's a noobie at a race is to see who's wearing the race day shirt during the race and then see who's doing people static stretches.

For 5K and 10K, I'll do an easy 3 miles with 4 strides, then change shoes to racing flats and do 2 more strides right before the gun.

10M and HM, I'll do an easy 1 to 2 miles with 4 strides.

Marathon, I'll just do some easy, light jogging. Maybe a half mile at the most. No strides.
