Cigna Healthcare Returns as Title Sponsor of the Denver Colfax Marathon

February 9, 2026

Denver, CO (February 9, 2026) /ENDURANCE SPORTSWIRE/ – The Denver Colfax Marathon is thrilled to announce that Cigna Healthcare has renewed its title sponsorship for the 2026 race season. As the marathon marks its 20th year, a significant milestone celebrating two decades of promoting health and community engagement, this partnership is a city-wide celebration of health within the Denver community. With Cigna Healthcare’s help, the marathon has invited thousands of runners through the years to join the journey of health and wellness locally.

“Cigna Healthcare has been an outstanding partner, bringing tremendous value to our runners and the broader community,” said Andrea Dowdy, CEO of the Denver Colfax Marathon. “Their ongoing support has helped us grow into an iconic event that inspires thousands to prioritize their health. We’re excited to celebrate our 20th year with them, creating even more opportunities for empowerment and vitality in Colorado.”

The Denver Colfax Marathon is the largest marathon weekend in the 8-state Rocky Mountain region and one of the top 25 marathon weekends in the country. With Cigna Healthcare’s continued support, the 2025 race weekend was the biggest marathon event to date, with over 25,000 runners in the Mile High. In 2026, the city will once again welcome runners from all 50 states and several countries for eight races over two days.

“Celebrating the Denver Colfax Marathon’s 20th year is about more than a finish line — it’s about the resilience that brings runners together, the community that lifts them up, and the well‑being we create through this extraordinary event,” said Brett Winingham, General Manager and Growth Leader for Cigna Healthcare Mountain States. “From first‑time 5K participants to seasoned racers, the marathon weekend shows how health, strength, and connection power Denver. Cigna Healthcare is proud to support an event that champions vitality across our city and makes wellness tangible.”

Cigna Healthcare is rolling out a new perk for this race season: runners registered for any race in the Denver Colfax Marathon weekend event can access a complimentary subscription to the Asics RunKeeper Go training app. The app features personalized training plans, guided workouts, and performance insights for runners of all experience levels. Participants receive a free six‑month trial to support their overall well‑being throughout their preparation, giving athletes even more tools to reach their race‑day goals in May.

Beyond the race itself, Cigna Healthcare is empowering thousands of local girls through their continued support of the Girls on the Run of the Rockies program. The company will once again sponsor complimentary entries for girls in the program to participate in the Denver Colfax Marathon 5K.

“Girls on the Run is about building confidence and healthy habits that last a lifetime, and Cigna Healthcare’s support makes it possible for more girls to experience that transformative power,” said Lisa Johnson, Executive Director of Girls on the Run of the Rockies. “In this milestone year for the marathon, we’re grateful for partners like Cigna who help us inspire the next generation to stay active and resilient.”

Girls on the Run is an after-school program that uses running to foster physical, mental, social, and emotional growth. Through its 10-week curriculum, girls train for a 5K while learning key life skills.

“By making running accessible and fun, we are building life skills to strengthen the wellness of Denver’s youth, families and our community,” said Donna Upson, Vice President of client management for Cigna Healthcare Mountain States.

In addition to Girls on the Run, the marathon supports more than 125 nonprofits each season through its charity partners program. In 2025, the Denver Colfax Marathon was proud to contribute more than ever before to local nonprofits through its one-of-a-kind charity program which has yielded over $10 million to local charities through the years.

Registration is open for the Denver Colfax Marathon which will take place May 15-17, 2026, and is expecting more than 26,000 runners for its 20th year. To register and learn more, visit www.runcolfax.org. Celebrate with us on social media: #RunColfax20
