Triathlon / Duathlon Venues in Colorado

Triathlon and duathlon venues in Colorado come in a few shapes, and this page lists them all: reservoirs and lakes with open water swim courses, recreation centers that host pool swim sprint races, and parks that serve as transition areas and run courses.

The outdoor multisport season usually runs from late spring through early fall, when water temperatures and weather cooperate. Early season races may use pools or be run as duathlons, and wetsuits are common in Colorado’s cool reservoirs. Altitude, wind and steep climbs make many courses challenging, which is part of the appeal. Indoor triathlons at rec centers give beginners a low pressure way to try the sport in the off season.

Open a venue to see its setting and upcoming races. Race directors can add a race free on CUP and reach multisport athletes across Colorado.

Your organization

Who is hosting, and how we reach you.

Beneficiary

Only if the event raises money for a cause.

Your sporting event

The basics we need to judge fit.

Out-of-state note: our standard pricing covers events held in Colorado. Events outside Colorado are quoted individually with travel and on-site costs included.
Worth knowing before you submit: our fully-managed service starts at 100 people on site. Below that the economics do not work for either of us, so this is likely not a fit. You can still apply, and you can always list your sporting event on the CUP calendar instead.
This one gets a custom quote. Our standard service model covers single-day events with 100 to 160 people on site, including vendors. Larger fields and multi-day events still work, we just scope them and send a custom quote instead of a standard price.

What success looks like

So we can tell you straight whether we are the right team.

Budget and timing

Fully-managed service is a real line item. Straight answers save us both time.

A CUP engagement runs roughly 150 to 200 hours of planning, design, marketing and coordination, handled by one team from the first call to the final award. Applications need a real budget line for professional management, separate from venue, food and prizes.
Worth knowing before you submit: a fully-managed engagement sits above this range, so this is likely not a fit for 2027. You are welcome to apply anyway. If self-serve is the better move right now, you can list your sporting event and add promotion here: list your event.
