I had plantar f. before my Boston Marathon in 1992 (which qualified me to represent at Barcelona Olympics) I incorporated aquatic training and bike for almost 45 days than gradually started to run on the road, track etc. I kept with aquatic training since (main part of my recovery and optimal athletic conditioning). Had plenty of sports massage and yoga sessions, but most importantly I trained with isokinetic resistive devices for the sport - not to lose the endurance and strength of my muscles and joints that I would used during my running.
