It's much better to go walk up the popular 14ers so a bunch of dorks will fangirl for you.
Go to boulder, and superior athletes will blow right past him without noticing. Seth would have a lot of unused footage that looks like "ohhh my my here comes [elite trail or road runner]. Hey how's it going, nice work! Hey where are you going? It's me seth demoor!"
Just joking, that actually could never happen. Seth seems to be super unwilling to associate with or promote anyone who threatens his ego - whether it's in the running or vlogging domains. Except for that random dude he ends up running next to (and getting beaten by) in his road races.
To top that off, do you know how many people would blow past seth as he bounces his way up our steep trails? His ego would be threatened on the daily, that's why he only shows up tapered, trying to set an fkt. And even then, Joe Gray ate his lunch.
