Marathon running has been booming for some time, triathlons have flourished recently and now people are flocking to gruelling assault courses. But how did recreational sport get so extreme?
It was once the case that a jog around the block was a respectable feat, but that's changed.
A half marathon, once the domain of the super fit, has now become rather tame. Today's barometer of fitness is becoming the triathlon and even this now has competition from Herculean assault courses that have competitors running through fire, mud and barbed wire.
But when did we become jaded with the usual forms of sport? When did recreational exercise become so extreme?

Orienteering is obviously not seen as extreme enough, as these extreme events and sports like Triathlon are booming whilst we are not. I don't have any answers, but knowing your competition and understanding why they are beating you is a start.
