The Bolder Boulder, a prestigious Memorial Day 10K, is set to draw nearly 53,000 participants this year, marking its highest registration since the pandemic recovery began. After significant setbacks during the pandemic, the race has rebounded impressively, closing entries ahead of schedule for the first time since its inception in 1979. Race director Cliff Bosley attributes this surge in interest to the growing popularity of running and outdoor activities, spurred by individuals seeking fitness during lockdowns. The 46th edition will feature an exhaustive range of competitors, culminating in a celebratory finish at Folsom Field.

By the Numbers
  • Approximately 53,000 entrants expected, the highest since the pandemic.
  • Entry figures increased from 33,991 in 2022 to 52,054 in 2024.
Yes, But

While interest in running appears to be on the rise, the race's previous years were marked by low numbers due to the pandemic. The 2022 race had the fewest registrations (33,991) in over three decades. Some may argue that the surge might not fully reflect the long-term sustainability of interest in road races.

State of Play
  • The race surpassed 1,000 registrations on the race morning for past editions, but this year will not follow that trend.
  • Interest in local races is also noticeable, illustrated by the Denver Colfax Marathon selling out its half-marathon recently.
What's Next

The Bolder Boulder will likely continue to see growth in participation as running and outdoor events remain popular. Future races could see adjusted operational capacities to manage the growing number of entrants. There might also be an increased focus on community engagement and local runners in subsequent events.

Bottom Line

The significant resurgence in registrations for the Bolder Boulder highlights a renewed public enthusiasm for running and community events. This momentum may pave the way for future growth in similar events, necessitating adjustments in planning and logistics to accommodate wider participation.
