Absolutely. Not only will they wick away sweat and remain very flexible, but also by keeping your running muscles tightly compressed, you should have a more comfortable run. This will allow you to focus on your pace and stride. Additionally, if once the race is over, you feel that your legs are extremely tired and fatigued, put on a fresh pair of compression pants to sleep. It may feel a little strange at first, but you will get significantly better recovery times.
