The Kybiru is an adventure triathlon including Kayaking, Mountain Biking, and Trail Running. The race takes place at the Harmon Lake Recreation area north of Mandan, North Dakota. It is like a traditional triathlon where the transition area is in one place. We have the well maintained mountain bike trail around Harmon Lake that is the highlight of the race. As you kayak across the lake you will get great views of the area. It is a beautiful location to have a race. We hope you consider the race this year. Please check out our website to find out more information at https://kybiru.com/.
The AlKemist Gravel Fest — October 4, 2025 | Mandan, North Dakota
Brewed for the Bold. Born on Gravel.
The AlKemist Gravel Fest was first brewed up in 2018 after exploring some of the most rugged and rewarding gravel roads in Morton County, North Dakota. Now it’s one of the region’s most anticipated fall gravel races — bringing together cyclists who crave challenge, community, and an unbeatable view.
Start your adventure at Graner Park / Sugarloaf Bottoms, just south of Mandan, ND, where you’ll climb out of the Missouri River Valley and onto the bluffs of Morton County. Every mile serves up fast descents, minimum-maintenance roads, and some of the longest climbs in the region — all balanced by wide-open prairie skies and unforgettable scenery.
When the dust settles, join us for post-race awards, hot food fresh off the grill, and a celebration worthy of the miles you’ve conquered.
