Conquer Wisconsin’s legendary red granite gravel routes amidst vibrant fall colors.

The Red Granite Grinder offers gravel cyclists the unforgettable experience of racing through Athens, WI on stunning red granite roads during peak fall foliage. Riders can choose from 50, 100, or 150 mile routes, navigating rolling farmland, forest canopies, and vibrant autumn landscapes. As part of the Ironbear 1000 series, the event is renowned for its scenic beauty, sustainability initiatives—like compostable materials and cupless aid stations—and a welcoming, celebratory atmosphere for riders of all ages and abilities.

Choose from three distances with varying terrain and technicality: 50 miles (86% gravel, 12% paved, 2% trail), 100 miles, and 150 miles. All courses feature rolling hills, well-maintained red granite gravel roads ('red gold'), rural paved sections, and some trail connectors. While specific elevation data is not provided, expect moderate elevation gain on undulating routes through Central Wisconsin.
