It's a commonly asked question, particularly when referring to events beyond marathon distance. Why? You'll often here barracking of a specific variety of acerbic whit and outright shock during training or when discussing events you do or plan to do:
"I don't go that far on holidays"
"You paid how much?!"
And the ever comedic and highly original, "Ruuunnnn, Forrest ... ruuun!"
But it's a fair question and, in particular, why 100 miles? It's time consuming, costly (though you do become desensitised to it after a while) and, if all of us that have done a few are honest, damaging if you're anything more than fastidious in you preparation, training and management during the event.
Resident barista at The Journey, Bargara and AAA Racing & Coaching regular Matt (Sandy) Grills (cover picture)is off to The Leadville 100 in August after a few years of missing out in the lottery. Matt's 'why' is evident if you follow his link, but the following might, just might give some insight as to why the rest of us do them.
