14th Annual Buffs4Life Kyle MacIntosh Memorial 5K Run/Walk 2026

The Buffs4Life Kyle MacIntosh Memorial 5K Run/Walk begins and ends at Franklin Field on the CU Boulder campus in Boulder, Colorado. This is a yearly Sunday morning 5K for runners and walkers, offering individual, duo, and family registration. The event is designed for all ages and abilities, suitable for families, casual walkers, CU fans, and those seeking a low-pressure run connected to the Buffs community. The route is not fully detailed, but the race is based around Franklin Field, with parking available in lots near Folsom Street. Current and former CU athletes, coaches, fans, and student-athletes participate. The post-race activities include breakfast from Pasta Jay’s, an expo, awards, food, music, games, and an autograph session. The Fun Run has generated over $100,000 for former CU athletes and their families facing hardship. The Buffs4Life Foundation has raised over $1 million across twenty years, with efforts including mental health resources and suicide prevention.
