1. GET YOUR ZZZZs
The more you sleep, the more virus attacking cells you'll produce-according to one study, 50 percent more after eight hours than after six.
2. RUN SHORTER
Thirty to 75 minutes of moderate activity can boost your ability to fight bugs; long, hard runs do the opposite.
3. ...OR DRINK UP
Consuming carb-rich drinks before, during, and after a run longer than 90 minutes can restrain immune-inhibiting stress hormones.
Pushing your body without enough rest can weaken your immune response-and cause frequent colds. Mood is an early indicator of overtraining, so take a rest day if you're feeling cranky.
5. STAY LOCAL
If you're really worried about getting sick, consider racing locally. Long trips can subject you to immune-system enemies like stress, poor sleep, and increased germ exposure.
HAPPY TRAINING AND RACING!
