Nick and Seth couldn't be more opposite on the physical spectrum. I would be VERY interested to see how a collab between the two would play out!!
Also, I'm not buying the fact that he had no idea Nick Bare uses "Go One More" as his slogan. Just a week or so ago Seth admitted to following "hundreds" of running YouTube channels and I can't see how Nick Bare would not come up as a suggestion in that pool.
What's more likely is that Seth doesn't follow any other YouTube channels (much like his Strava). In fact, I specifically remember him mentioning how he purposefully does not watch any other running related YouTube content because he does not want to be "influenced" by anyone else. I wish I could find that vlog and post it here. This was back when I would watch regularly, before he started charging for emojis and shouting catch phrases. That statement lines up much better with Seth's current image of a solitary running bubble. No coach, no training buddies, no group runs (other than the 2-3 races he does each year where he can't avoid it). Just Seth and his devout DGR cult that will pay to support his lifestyle month after month and only post positive comments that stroke his ego.
