Ever been to a doctor whose solution to any injury you have is to tell you to stop running? Thankfully, we haven’t, but we know they re out there. The Times solution — see a doctor who’s also an athlete. Or you could just try to find a doctor who actually knows what he s talking about when it comes to training — like our sports doc, who isn’t overly athletic himself, but has treated enough athletes to know what to recommend) — but it’s so much easier to just check the wall for race photos.
