To help your body bounce back from distance running, listen to Dave McGillivray, race director for the Boston Marathon -- and a marathon runner himself -- and his frequent running partner Josh Nemzer.
"Recovery from a long run begins immediately after you finish it," McGillivray says:
* Keep moving. After a run, try to walk for at least five minutes instead of immediately coming to a full stop, which can cause cramping, nausea or dizziness. Once you stop, do some light stretching to boost circulation to muscles.
* Replenish fluids. No matter how much you've had to drink on a run, you'll need water or sports energy drinks as soon as possible after the finish to guard against dehydration. Stay away from soda, alcohol and caffeine.
