2027 Sparks Backyard Ultra

Race Information

The Sparks Backyard Ultra, part of the Biggest Little Ultra series, throws out the usual race script and challenges runners in a truly unique way. Instead of a set distance or finish line, participants run a 4.167-mile loop every hour, on the hour, returning to the start each time to begin another lap. You keep going as long as you can — the race continues until there’s only one runner left able to complete a loop in the allotted hour, and that last person standing is crowned the winner. It’s a simple concept with brutal demands, blending endurance, strategy, and community on a scenic loop around Sparks Marina.
