Sunderbruch B&B Trail Races

Sunderbruch B&B Trail Races : May 16, 2026

The Sunderbruch B&B Trail Races are trail running events at Sunderbruch Park in Davenport, Iowa, presented by Quad Cities Trail & Ultra Runners and Sun Trail Running. The event offers measured courses that are approximately 5k and 10k on the park's single track and connecting trails.

• 10K Approximately 10k on mixed single track with climbs, descents, technical sections.
• 5K Approximately 5k following green and blue mountain bike trails, mostly flat.

The courses are about 90% dirt single track with a short section of mowed grass and a parking lot parade loop near the start. The 10k includes sharper climbs and technical stretches and the course route can vary year to year. The course will close at the three hour mark and volunteers will be removed at that time or when the last runner passes.

This is a cup free race; runners should carry fluids or bring a vessel to refill at aid stations. Registered entrants receive a B&B mug and limited collapsible silicone cups will be available for purchase at packet pickup. Post race provisions include a potluck with bacon and craft beer, and the event makes a guaranteed donation to Friends of Off Road Cycling.

Registration is online only, closes May 8 at 11:59 PM CT, and there are no refunds or bib transfers. A waitlist and a one year rollover deferral option exist; the deferral deadline is April 23. Packet pickup is Thursday evening at Stompbox Brewing, Friday evening at Sunderbruch Park, and Saturday morning. A free kids race for age 10 and under is held Friday at the park during packet pickup.
