Join us for the Left Hand Brewing Half Marathon and 5k on April 19, 2026! 

Course: The Half-Marathon and 5k will start and finish on the north side of the Left Hand Beer Garden, and will follow the St. Vrain Greenway to the east. The course is out and back, following the same trail back from the 6.55-mile turnaround point. The trail is mostly flat, with a modest ~300ft elevation loss on the way out. Aid stations will be available every 2-2.5 miles. Carrying your own water bottle or hydration pack is recommended. You may refill either at our aid stations. Toilets will be available at several locations throughout the course as well as at the start and finish line.

All participants receive:

• Short-Sleeve Unisex Tech Shirt for all Half Marathon registrants and a regular unisex T-shirt for all 5k registrants who sign up by April 10th. Size and availability are not guaranteed after April 10th. If shirts are no longer available, alternate swag rewards will be handed out to late registrants.
• FREE Left Hand Brewing beer at the finish line for all 21+ runners
• Finisher's Medal to all Participants
• Your chance to win sweet door prizes from the Colorado Brewery Running Series, our event sponsors, and Left Hand Brewing Company.
