Set your sights on the challenging yet stunning Mines of Spain Trail Races, taking place on August 8, 2026, in Dubuque, Iowa. Starting and finishing near the E.B. Lyons Nature Center, this event immerses runners in the heart of eastern Iowa's unique driftless region. Participants can choose from a Half Marathon, 7-mile, or 4-mile distance, each promising an unforgettable trail experience. Typical race day conditions in early August bring highs around 83°F and lows around 64°F, with a 15% chance of precipitation.

The courses traverse a diverse landscape, featuring mixed terrain including challenging single and double track, sweeping prairie grass trails, rocky technical sections, and dense hardwood forests. Prepare for significant elevation changes, particularly in the half marathon which boasts approximately 666 meters (over 2,000 feet) of gain and loss, as you climb bluffs for breathtaking views of the Mississippi River valley. While demanding, runners consistently praise the inspiring scenery and well-maintained trails. Aid stations provide water, Tailwind Nutrition, and snacks, though runners are encouraged to bring their own hydration as it's a cup-free event.

Beyond the physical challenge, the Mines of Spain Trail Races offer a rewarding atmosphere, celebrated for its grassroots feel and commitment to sustainability with a zero-waste approach. Profits from the race directly support the Friends of the Mines of Spain, aiding in trail maintenance and preservation. Conclude your effort with a renowned post-race celebration, featuring delicious brick oven pizza and local craft beer, making this a truly memorable event for all trail enthusiasts.
