I watched it. It's hilarious. Each episode is like 20 minutes, so perfect to watch while doing some post-run stretching and foam rolling.
The series just started, but it seems like the writers are actually fairly knowledgeable about running (at least compared to most depictions of running on film). Presumably a bunch of nobodies are going to do something impossible at the end, but as they tell you in fiction workshops, one unrealistic thing is just called a premise. The two fast guys are not "former D1 runners." They were really good high school runners who never ran in college. They're at a school that doesn't have a team, but one dude basically tricked a bunch of people to move into the former track dorm. They didn't realize a condition of residency is that they run on the team. Of course, to qualify for Hakone (the goal) a bunch of novices need to be 1:03 half marathoners in about ten months:
