I was thinking more along the lines of a "Top people" Beer Mile
One day, four laps, good laughs, a bunch of YouTube / IG content; easy-peasy, in & out
ETA: Backyard/"laps for time" format does NOT make it an Ultra - you have to exceed 26.2 miles/42K to call it an Ultra, so someone would have to complete 9 x 5K laps to claim
"What's your claim?" - Ben Gravy
"Your best work is the work you're excited about" - Rick Rubin
