Makeup that won't come off in gym cl?

I take care of my skin (on my face) as well as I can, but acne is still occasionally a problem. I also have a red undertone to my usually pale skin, so concealer & foundation is a must. The problem is, school starts August 10th and I have gym cl until Winter Break, a little before the 20th of December. We run, play sports,do bikes/rowers and lift weights, so we obviously sweat. My gym period is 3rd, so I really don't want to sweat off makeup, and as I don't have time to re-apply any (we get five minutes to change, I focus that time on clothes, perfume/deodorant, and hair!) go around like that for the rest of the day... so long story short, whats a TRULY sweat-proof make-up that has great coverage?
