What's New in Ultrarunning?

In the late 18 hundreds, there were a hundred milers who could do it in under under 13 hours. But then when janis curris came round, ime, he really took it to a new level. So i think what's changed too, is then in the nineties, things shifted away from roads to trails. And where that became more popular, a lot the hundred miles on on roads and tracks started to disappear. People liked to have adventure more than they did going after specific records.
