I just did an invitational bicycle ride a couple weeks ago and saw a rider limping very badly at one of the rest stops. He told me he had plantar fasciitis and meds and physical therapy had not helped. 
This is a condition that I frequently treat which is many times the result of biomechanical dysfunctions of the foot, ankle, knee, and/or hip. The incidence seems to be increasing probably due to the weight increase of Americans and the increased participation in sports and exercise.
Anyone experienced this condition?
