Ultrarunner Karl Meltzer is on Day 3 of a fully-supported (i.e. food stops and lodging provided by crew at road crossings) attempt to set a thru-hike record by running the AT in 47 days. That’s only 50 miles per day. Ish. While I’m sure that the ultra crowd is behind him, the AT crowd is certainly split on whether one “should”, whether record attempts are in the spirit of the trail, etc. I’m sure he can physically and mentaly do it – it’s been done, he’s only attempting to shave a few hours off the current record. It will just be a matter of avoiding Murphy’s Law for 47 consecutive days, which is a tall order. It will be interesting to watch. Here.
