The Denver Colfax Marathon Relay 2026 distributes the full marathon distance across a group rather than requiring a single athlete to cover the entire course alone. This relay format turns a solitary endurance challenge into a shared team effort, opening the marathon distance to running clubs, corporate squads, and friend groups that want to complete the event together. The event is worth planning around because the official leg overview details how the distance breaks into segments, letting teams plan which runner covers which stretch before race day. The official Colfax Marathon site consolidates the course layout, the relay map, and the 2026 team instructions, so participants can review the route, check leg boundaries, and confirm entry rules before race day. Reading these pages before race day prevents roster errors and clarifies where each runner transitions between legs.
Marathon relay course
The Marathon Relay Leg Overview - Denver page describes the relay course legs and explains how the full course breaks into segments, marking where one leg ends and the next begins. Teams split the distance among assigned members so each runner covers their portion instead of one athlete running the whole event, and the page sets out how each runner covers their leg and where the team transitions between legs. This structure matters for pacing and preparation, because participants can assign roles to specific stretches before race day. The Marathon Relay - Overview page describes the overall relay format and team structure, confirming how the relay fits into the wider Colfax Marathon event and who the format suits.
Relay route map
The relay-map page provides the official Colfax Marathon Relay route map, showing the course layout through Denver neighborhoods with each relay leg's boundaries marked. Teams can check the map ahead of race day to locate exchange points and see how the legs connect from start to finish. The map serves as the primary visual reference for understanding how the relay legs fit together, letting groups visualize the route their runners will cover and helping participants identify where their leg begins and ends relative to landmarks along the course. Seeing the full course on one page supports logistics planning for spectator drop-off points and team transport between exchange zones.
Team registration and relay instructions
The Relay Instructions 2026 PDF covers the 2026 relay team instructions, laying out rules for registration, runner eligibility, and race-day expectations. The document covers who may enter and how teams assign roles, so groups can review eligibility requirements before signing up. All team members must be registered, and legs cannot be swapped once assignments are made. Reading these instructions ahead of time prevents registration errors and ensures every runner meets the entry requirements set by the organizer, so teams should review the document carefully before finalizing their roster. Practical details such as hours and parking vary by exchange point, so the official overview page remains the current reference for logistics.
