YouTube algorithm is innundating me with Barkley Marathon videos since it has been going on live right now and I am here for it :). For those who don't know, it is considered one of if not the hardest ultramarathons on the planet. Only 17 people have finished it since it was created in 1995. #YouTube #running #BarkleyMarathon
