BOULDER, Colo. – The BOLDERBoulder 10K announced today that the event will not be able to offer race weekend or race day registration for the 2026 race.
Historically, the BOLDERBoulder has offered participants the opportunity to register during race weekend and on race morning. However, with participation numbers trending significantly higher and the event approaching operational capacity, organizers are encouraging anyone planning to participate to register as soon as possible.
“We are seeing tremendous excitement and momentum heading into this year’s race,” said Cliff Bosley, BOLDERBoulder race director. “As participation continues to trend toward operational capacity, we want to ensure the highest-quality experience possible for every participant.
