For spectators and fans, the 118th Boston Marathon ended yesterday; but for many runners, the 26.2 mile run-of-a-lifetime will stay with them for weeks - even months- through the pain of injury. In fact, incidence rates for injuries reported for athletes training for marathons can be as high as 90%! Of those,about 15% of all running injuries strike the foot. This is not too surprising since each step, our feet absorb several times our body weight. One common runner’s injury is Plantar Fasciitis.
