For the first time in the history of a race that began in 1979, the Bolder Boulder was forced to turn away potential customers.
Organizers cut off registrations for the 2026 Bolder Boulder on Friday night at midnight, citing an entry total that was pushing the race to its operational capacity. The 46th running of the Memorial Day 10K on Monday showcased why the unprecedented cutoff was necessary.
The final tally of entrants topped out at 53,801, the Bolder Boulder’s largest turnout since a record 54,554 entered in 2011. Monday’s total was the fourth-largest number of entries all-time, trailing only 2011, 2008 (54,040) and 2010 (53,992).
“We talk about numbers, but we don’t want to chase numbers. But we have to talk about it, because it’s a derivative of the operational capacity. But there’s huge pride with our team. I don’t think it’s anything that we’re doing. I think it’s what we’ve done, and the history and tradition continues to be something people are excited about.” – race director Cliff Bosley
