Halloween Costume Run & Mixed Relay 🎃👻

Join Bullfrog Running and Embrace the Pace on October 30, 2026, for a spooky night at Cheesman Park. The Halloween-themed run invites runners to dress up in their most creative costumes as they explore the park's eerie trails under the glow of lanterns and moonlight. Participants will hear chilling tales from local lore while mingling with fellow runners before being randomly assigned to mixed relay teams for an exhilarating lap around Cheesman’s inner loop. Prizes are awarded for both best costume and winning relay team, encouraging spirited competition among friends or newly made acquaintances. After the race, stick around for snacks, drinks, glitter stations, and more Halloween fun as you share stories and laughter with fellow revelers in this festive atmosphere.
Join us solo or bring a friend to experience one of Denver's most unique running events.
