The more I think about it, the more I think Choi is the perfect guy to obnoxiously promote your marathon.
Not fast enough to impede the times that actually matter, and too fast to accidentally clothesline a baby stroller or little old lady. Just fast enough that the only people he’s gonna piss off are a bunch of mediocre LR guys, who don’t talk to actual runners and will instead express their displeasure by aggressively reposting his content on a poorly regarded and borderline unreadable internet forum, before probably signing up again next year anyway.
Cost-benefit, clear winner.
