Centennial Reserve, “The Scenic,” shapes this backyard ultra: off-road trail loops, the corral, the bell, and the slow stripping-away that comes with a “last one standing event.” Scenic Circles Backyard Ultra is brutally simple in the way only this format is: start every hour, finish in time, stand there again when the bell goes.
You run 6.7056 kms every hour, on the hour, until everyone else is gone; the winner is the “last person to complete a loop.” Bring your own plan and your own supplies, because this one is self-supported: all food and fluids are on you, and “there is no aid station provided.” That makes the race feel less like a catered trail day and more like a test of pacing, setup, and whether you can keep choosing one more loop.
