Louisville, Colorado Turkey Trot 2026
The 13th Annual AdventHealth Avista Louisville Turkey Trot began as a way to collect food and donations for our local food bank, Community Food Share, while bringing our community together on Thanksgiving morning.
As the event grew, the Turkey Trot became a public benefit corporation, allowing us to operate with the purpose of creating social good and supporting our community in a responsible, sustainable way.
Event Details
Date: November 26, 2026
Race Start: 9:00 a.m.
Location: Front Street & Spruce Street (951 Spruce Street, Louisville, CO 80027)
Registration
Yes—you must register! Your entry fee and food donations directly support Community Food Share, whose mission is to eliminate hunger in Boulder and Broomfield Counties.
Every $1 donated = $6 worth of groceries
Last year’s race raised over $92,000, and we’re aiming even higher this year.
Although the event began as a free run, we introduced an entry fee to make a larger impact. If you plan to trot, please register to support the cause.
To keep the event accessible, our entry fees are significantly lower than most races, with early pricing nearly 50% off race-day registration. Help your friends and family save by encouraging them to sign up early!
We keep costs low by skipping bibs, shirts, and chip timing—so more of your entry fee goes directly to Community Food Share. Thanks to our partners, all participants enjoy complimentary coffee, hot cocoa, and beverages (21+ with ID).
This event is all about community, connection, and giving back.
School Grant Program
Back this year! In addition to supporting Community Food Share, your registration now helps local schools through our brand-new Louisville Turkey Trot School Grant Program.
Beginning in 2025, we will award $500 grants to the Elementary, Middle, and High School with the most registered participants. Students, families, teachers, staff, alumni, and supporters all count toward a school’s total—just enter your school at registration to make sure your participation is included. Rally your community and help your school make a strong showing.
Run, walk, or trot for your school—while supporting families in need this Thanksgiving.
