Embark on a memorable trail running adventure at the Sunderbruch B&B Trail Races, set for May 16, 2026, in scenic Sunderbruch Park, Davenport, Iowa. Offering both an approximate 5K and a more challenging 10K distance, this grassroots event, organized by the Quad Cities Trail & Ultra Runners (QC-TUR) and Sun Trail Running, promises a day of fun, camaraderie, and picturesque singletrack. Typical race day conditions feature comfortable highs around 73°F and lows near 51°F, with a modest 19% chance of precipitation, though a backup course of grass and paved paths is ready if trails are too wet.

The courses predominantly weave through the beautiful wooded scenery of Sunderbruch Park, renowned as the "crown jewel of off-road riding in Davenport," with 90-95% dirt singletrack trails. The ~5K route is generally flatter with gentle rolling inclines, traversing green and some blue mountain bike trails, making it ideal for newer trail runners or those seeking a quicker pace. For a more exhilarating experience, the ~10K course, which evolves annually, incorporates quick, sharp descents, challenging climbs, and technical sections, including rooted terrain and creek crossings. Both distances begin with a short parade loop in the parking lot to help spread out runners before diving into the main trails, and both are designed to be enjoyable for both seasoned trail veterans and rookies alike.

Beyond the trails, the Sunderbruch B&B Trail Races are celebrated for their welcoming atmosphere and unique post-race festivities, truly embodying the "B&B" in its name with an awesome potluck featuring free bacon and craft beer. This cup-free race encourages sustainability, providing on-course aid and requiring runners to bring their own hydration vessel, with a custom race mug included in registration. Runners consistently praise the event for its friendly vibe and the beauty of the 10K course as a "doable challenge." The event also proudly supports the Friends of Off Road Cycling (FORC), contributing to the ongoing maintenance of these exceptional trails. The start/finish area and parking are conveniently located on the north side of Sunderbruch Park, off Telegraph Road.
