It is vital to keep from overheating by drinking plenty of fluids, not running on very hot days, and not exercising too vigorously. Lower back pain can be a problem at this time. Even the non-pregnant runner can benefit from putting her feet up, since resting with elevated legs is helpful in the prevention of varicose veins. Now is the time to take running easy, since relaxation is valuable preparation for delivery. Preparation for birth is somewhat like getting ready for a marathon or an important race.
Emotion has to be channeled for constructive use.
Concentration and calmness are valuable tools. Labor is not necessarily easier in the runner than in the non-athlete, but a runner will know how to persevere and make use of her physical strength when necessary. Runner tummy muscles are a definite asset. After at least a month's rest, the new mom will find that her former running paths seem to have doubled in length, and her legs will probably seem twice as sluggish. It takes some time to come back, but it may serve as motivation to know that many women find that their post-pregnancy race results are substantially better than before.
