I have been running for some 40 years and still get a buzz from it especially races. The effects on me well I have osteoarthritis in left hip but has so far not stopped me running. The most common recurring ailment over the years has been that old fav for runners PF (plantar fasciitis) which comes and goes. I include a massage in my routine and cycle to and from work each day. I take all the usual supplements not sure if they help but take anyway...so what are your recurring aches?
