Lyons-Heart Gravel Classic - Premier Gravel Bike Race in Mandan, North Dakota
About this race
Lyons-Heart Gravel Classic — July 11, 2026 • Mandan, North Dakota
A premier gravel event carved along the Heart River: choose the 35-mile non-competitive ride, 65-mile race, or 100-mile test of endurance. Celebrate at the downtown Mandan finish line with live music, vendors, and community festivities.
We took a favorite local gravel route shaped by the Heart River and expanded it to give cyclists a fresh opportunity to explore North Dakota’s rolling landscape. Expect winding descents through the Lyon’s Den, punchy climbs that prove North Dakota isn’t flat, and long stretches of scenic gravel that reward pacing and line choice. The course was designed for fast riding, spectator opportunities, and an unforgettable finish in downtown Mandan — Where the West Begins.
