I've been volunteering and working with Grandma's Marathon for the last decade, but I've never ran it. I thought I had a good idea of what the race would be like from a runner's point of view, but I still learned a bit from this guy's video on YouTube from the 2017 Grandma's Marathon.

First off, hats off to this guy "Wilderness Enthusiast" for finishing.  Secondly, kudos for being able to take video of the whole thing and edit it up.  You can tell in the last few miles he was clearly just trying to make it, but he never gave up on the race or getting footage!
