SUMMARY:BOLDERBoulder 10K
DESCRIPTION:The BOLDERBoulder 10K is one of the largest and most beloved 10K races in the world — billed as “America’s All-Time Best 10K” and drawing more than 50\,000 participants every Memorial Day to Boulder\, Colorado. Founded in 1979 by Olympic marathoner Frank Shorter\, the race has become a Boulder institution that combines elite-level international competition with a costume-filled community festival. \nThe Famous Wave Start\nBecause of its massive field\, BOLDERBoulder uses an innovative wave-start format with more than 100 waves separated by a few minutes each\, organized by predicted finish time. The system lets runners of every ability — from sub-30-minute elites to family walkers — start with peers at their pace. It also turns the race into a parade that lasts most of the morning\, with bands\, dancers\, slip-and-slides\, and belly-flop pools lining the course as runners flow through Boulder’s neighborhoods. \nCourse and Finish at Folsom Field\nThe 10K course winds through Boulder’s tree-lined streets with the dramatic Flatirons rock formations rising on the western horizon. The course climbs gently and finishes inside the University of Colorado’s Folsom Field football stadium\, where every finisher runs around the field to the roar of tens of thousands of cheering spectators. The finish-line crowd inside the stadium is something every U.S. runner should experience at least once. \nMemorial Day Tribute\nAfter the citizens’ race\, BOLDERBoulder hosts a moving Memorial Day Tribute inside Folsom Field featuring a parachute team\, military flyover\, and ceremonies honoring fallen U.S. service members. It’s one of the most meaningful Memorial Day observances in American sport\, and many runners stay to watch. \nRace Details\n\nLocation: Boulder\, CO — start downtown\, finish at Folsom Field\nNext Date: Monday\, May 25\, 2026 (Memorial Day)\nStart Time: First wave 6:40 AM (waves continue throughout the morning)\nDistance: 10K (6.2 Mile)\nField Size: 50\,000+ participants\nElevation: ~5\,400 feet — runners should plan for altitude\nIconic Feature: Finish line inside Folsom Field football stadium\nCategory: Road Race — iconic\, holiday\, family-friendly\n\nWhy It’s a Bucket-List Race\nBOLDERBoulder has been featured in Runner’s World as one of the must-do U.S. races for good reason. The combination of altitude\, scenery\, costumes\, course entertainment\, stadium finish\, and Memorial Day tribute creates an atmosphere unlike any other 10K in the world. Highly recommended for runners visiting Colorado or building a destination running calendar. \nRegister and learn more on the official BOLDERBoulder website.
