About this race
Event Details
- Date: 2026-09-26
- Location: 307 Agnes St, Port Byron, IL
- Race URL: FORCn DURO 2026
Race Overview
Can you Duro it? RIDE-TO and RIDE-AT 8 trail systems in one day? 60 miles of pavement & 40 miles of singletrack. 100 miles total. The FORC'n Duro is the ride of all MTB rides in the QC and probably one of the hardest days you'll have on a bike. Riders will be tested mentally and physically as they make their way from Dorrance Forest Preserve in Port Byron, IL to Westbrook Park in Dewitt, IA - while hitting tons of singletrack trails in between (Dorrance, Illiniwek, Sylvan Island, Sunderbruch, Scott Community College, Lost Grove Lake, Scott County Park and Westbrook Park): 100 miles in total.
Alternative Options
- Dirt Duro: Not ready for the full 100 miles? Do the DIRT Duro and ride all trails in one day. 40+ miles of single track is a pretty respectable day!!
- Flexible Riding: Not in for the long haul? Join us anyway and ride what you want/can.
- Riders Meeting: A riders meeting will be held in the shelter at 6:50am where we will go over route cue sheets and other last-minute information.
- Support: This ride is semi-supported. Bring tools, tubes, a pump, and any other gear you need to fix minor mechanical issues.
Rest and Refuel
- Refuel Station: A refuel station will be located at Healthy Habits a little past halfway.
- Convenience: There are plenty of stores along the route to refill and refuel.
Important Notes
- Self-Sufficiency: This year is more self-sufficient so bring the necessary tools and spares for a full day ride, and have a friend on call for bailing out if you have serious mechanical or other problems (ideally someone riding the Dirt Duro who is likely nearby).
- Route Changes: This year’s Route will include Scott Community College and a fun grass section around Lost Grove Lake on the way to Scott County Park. And exclude Stephens, Dog Park and Eldridge Rail Trail.
- Rain Date: Rain date will be Saturday October 3rd.
- Membership Requirement: MUST BE A FORC MEMBER TO PARTICIPATE.
