    RACE POSTPONED TO 2027

    We regret to inform you that the 2026 Dash for Detection: Oral Cancer Awareness 5K has been canceled. Due to circumstances beyond our control, we were unable to secure the necessary credentialing to move forward with the event this year.

    All registered participants will receive a full refund of their race registration fees within the next few weeks. No further action is needed on your end.

    While this is not the news we hoped to share, please know that our commitment to raising awareness for oral cancer and supporting those currently battling the disease—as well as honoring those we have lost—remains unwavering. We are already exploring alternative options and beginning preparations to ensure the 2027 race is even bigger and better than ever.

    Thank you for your understanding, continued support, and belief in the mission of Dash for Detection.

    Please reach out if you have any questions or concerns,

    All my best,

    When: April 24, 2026 | Meet up: 5:30pm, Race: 6:30pm, Finals: 7:30pm, End:10pm

    Where: Little Machine

    Join us for the fourth round of Hot Laps sponsored by Runners Roost and Citius RC powered by On. The rules stay the same this year, but the course takes steps elsewhere. Teams of four race to complete as many laps as they can in 45 minutes. The top five teams with the most laps progress to a final round where the fastest laps win.

    Relay teams are mixed gendered and created by racers before they sign up. Each team must have at least one member of the opposite gender (2 girls/2 guys, 3 girls/1 guy, etc.) Teams can pick up race packets the week before at Runners Roost | 1685 S Colorado Blvd J, Denver, CO 80222. Or come early to check-in before 5:50pm on April 24th.

    Hot Laps takes inspiration from the motor racing world where cars compete on fixed courses to complete as many laps in a set time.

    Similar to the world of car racing, Hot Laps require teamwork. Mixed gendered teams will compete on an unsanctioned course where each member has to exchange in a predetermined zone. At the 45 minute mark, teams will total their laps and the teams with the most laps will advance to the final round.
