Update after 15 days
929.9 miles which averages 62 miles per day.
It looks like he is trying to push for more miles in the last days. I hope that will work out. There is a fine line you don't want to cross. Once you have shins splints the fun will be over and it will be super painful onward.
Nels comment on Strava:
Finally ending the evening in a location with cell service. The last two days had their fair share of climbing and my legs felt pretty trashed after yesterday constantly jumping off the shoulder to avoid huge trucks (and trying to not scare free range cows into the trucks). Denise did some awesome massage work on me last night and my legs actually ended up feeling good today.
Paul Nielsen put a bunch of miles in with me the last h two days and Ruth Kohstall put in 8 miles today. Got an awesome cinnamon roll from Black Sheep Coffee Company in Duchesne that gave me a second wind today. The pictures are combined from the past few days.
