Bear Creek Backyard Ultra

The Bear Creek Lake Park Backyard Ultra offers an intense and unique endurance challenge for runners seeking an unforgettable experience on October 31, 2026. Set against the backdrop of Lakewood's serene Bear Creek Lake Park, this race begins at 8:00 AM with a staggered start format that sees participants completing a grueling 4.16-mile loop every hour.
Each lap starts precisely when the next full hour strikes, and runners must be back at the starting line ready to begin their next circuit on time or face elimination from the competition. The race continues until just one runner remains standing or is halted by Bear Creek Lake Park's official closing hours at 6:00 PM. With a field capped at fifty competitors, this event promises an intimate and focused atmosphere where every lap could be decisive.
The park itself offers scenic trails that wind through natural beauty, providing both motivation and respite for those pushing their limits hour after hour. Runners will benefit from the sole aid station located conveniently at the start/finish line, offering essential hydration and nutrition with each loop completed.
Entry to this exclusive event is $65 per participant, which includes admission fees for Bear Creek Lake Park itself. As the race progresses through the day, competitors must stay sharp both mentally and physically as they push against their own limits in pursuit of victory or simply the satisfaction of enduring another hour.
For those who love pushing themselves beyond what seems possible, this Backyard Ultra is a thrilling test that combines strategic pacing with raw endurance under the watchful eye of nature.
