This barefoot run is pretty damn epic. Two dudes both in their 40s, one who shattered his pelvis jumping last year and broke his neck, also jumping, a few years earlier. (might want to think about not jumping...)
These guys just get beaten on in these runs, the skin on their feet burns and tears, some have trouble walking for weeks afterwards, its ugly. And these old broken down guys beat all the young punks. Bunch of bad asses really.
Barefooting, your doing it wrong.
