Starting in 2025, the DKAT became the main event, this continues in 2026.
The Doc King Adaptive Tour is a ride that gives adaptive cyclists an opportunity to demonstrate their riding skills on a highly-visible course. The course in 2026 will be along the Portsmouth Rail Trail, starting at the skate park. This is one event where the spectators have as much fun as the participants!

Previously this “event within an event” allowed spectators to cheer on the Doc King Adaptive Tour riders while King Challenge route riders complete the road course. Started in 2025, the DKAT is the main event, now moving from community campus to the Portsmouth Rail Trail.
Adaptive cycling equipment is rented from Northeast Passage. Northeast Passage and Krempels staff and volunteers will be available to support and ensure a safe and enjoyable riding experience.
