Last Call Triathlon

Last Call Triathlon is a multi-discipline lake event held at Boyd Lake State Park near Loveland, Colorado. The 2027 edition is the ninth annual running of this late-September event. The venue offers on-site camping and parking lots located within a short walk of the transition and start areas; a parking pass is required for vehicle entry.

Race formats and distances include:

• Sprint Triathlon: 750 m swim, 10 mile bike, 3.1 mile run
• Sprint SUP Triathlon: 750 m SUP, 10 mile bike, 3.1 mile run
• Supersprint Triathlon: 450 m swim, 4.9 mile bike, 2.15 mile run
• Duathlon: 2.15 mile run, 10 mile bike, 3.1 mile run
• Aquabike: 750 m swim, 10 mile bike

Swim courses are single loops marked by buoys; surface temperatures are estimated around 65–70 degrees. SUP athletes stage near the swim flags and are staged into the water. The primary bike course uses two loops with a mix of smooth center-road sections, bike paths, and sections of older pavement with turns. Run courses follow wide, paved pedestrian paths with marked signage.

Event logistics note mobile toilets in transition parking lots, water jugs on the bike aid station (no single-use plastic bottles), and biodegradable cups at the run aid station. The event is USAT sanctioned and described as a 100 percent plant based event. Visit the organization's website for the most recent information.
