Make sure you are well rested.
No last-minute cram training in the days leading up to the race. Remember DOMS sets in 48 hours post exercise, until this time your body is in repair mode and wont be at full function or strength. Try to keep active in the days leading into the race but keep exercise gentle and low intensity. Of course there are exceptions to this rule and some short high intensity bouts of exercise that don’t cause fatigue have been found to be beneficial.
OUCH! That Hurts…
What is DOMS?
Delayed onset of muscle soreness is the pain you feel in your muscles a day or two after doing exercise. It can range from a feeling of tightness with going down stairs for example, to severe pain.
