At Greenvale, the loop is the entire course: grass and gravel underfoot, with 311 feet of climb on the day loop and no hiding from the repetition. Greenvale Backyard Ultra is a backyard ultra in the strict sense, built for runners who understand that the hard part is not one lap, but answering the bell again and again. The current loop record is 38, set by Ryan Crawford in 2024.
Runners cover the same loop for the entire race, then use whatever time is left in the hour to reset before going again. The field is capped at 100, so it should feel more like a focused ultra crowd than a large start line. The quirk is also the cruelty: a "last man standing format," where finishing fast only buys you a few more minutes to sit, eat, change socks, and decide whether you are still in.
