There is a guy I saw on IG, Kevin Hopp.. I heard him on the rambling runner podcast earlier this year too..regular late 40s Dad/Teacher in San Diego, his running stats are sheer insanity..
He's on his 5th week of 180+ mpw..he's running a marathon everyday this summer, his goal is 70 marathons in 70 days, and he's on like 46 I believe..dude is an absolute riot to follow.
