Hello. What is the race? Also why 24hr and 10hr countdowns I don't understand the differences.

It's a Backyard Ultra. So 4.165 miles per lap, one lap on the hour every hour until only one runner finishes the last lap. The countdown is at the beginning of the day recorded, that many days and hours left, and at the end of recording, (not exactly but at 9pm) the hours left. It's also a nod to the show 24, one of my all-time favorites
