I always thought that the three elements of the triathlon were distinct and separate, the swim followed by the cycle followed by the run. Well on Saturday I came upon the Causeway Coast Triathlon. I was informed that the competitors would swim two laps of a marked course just off the strand. What I wasn't told was that between each lap the swimmers would exit the water, and run along the beach for a couple of hundred yards before plunging back into the water. Strange that. Well I thought that it was. No doubt afficianadoes of the world of triathlon will now tell me that it is quite usual but the purist in me tells me it isn't quite right. A quadathlon can't be a triathlon? Can it?
