Running with leg sleeves

I've been trying to decide if I should run the race with leg sleeves or not. I didn't train in my long runs with them on, so I don't know how they'd feel after more than two miles. Tonight's run was two miles, so I figured I would try them. If they're really bad I give them up for the race. They actually felt good while I was running, but they made my legs warm. Since I perform better in cooler weather, warming up my legs seems counter-productive. Ultimately I think it will depend on how cool the race morning is. It doesn't look like that day will be cool, so I'll probably leave them off and use them post-race.

I decided to try and run faster today since it was just two miles. Yeah, I totally got way too excited in the first mile and wasted my energy. The second mile was okay, but my left calf was mad at me. It was just a harsh reminder that pacing is still important, even at the shorter distances.
