Corporate Marathon Relay

Colorado’s Largest Corporate RUnning event!

What’s better than running 26.2 miles through the Mile High City?  Sharing the miles with co-workers!  Get teams of five employees each to run Denver’s only 26.2 mile Marathon Relay – and Colorado’s largest Corporate Race.  See the great sites of the Mile High City on each leg – from Empower Field at Mile High to the Confluence, Sloan’s Lake, downtown, or the neighborhoods around Colfax – which one will you run?  The ultimate team-building experience.

You register your team(s) in your industry – and if your team is fast you could even win bragging rights, awards and money for charity!


How to purchase entries and get organized!

HR DIRECTORS – You can buy multiple registrations all at once for your employees and teams.  And, if your company has FOUR or more relay teams, you can have a company party at the Finish Line – information will be emailed to team captains of qualifying teams in late April or early May.

TEAM CAPTAINS – You can register your team, and enter the runners’ names later!  Your 5-person team can be coed, male, or female
