The course is a serious affair (45 miles of rolling terrain) but the Grinduro isn’t meant to be a sufferfest. We’ve linked together some of our favorite roads and trails on the Isle of Arran. With spectacular scenery and a friendly pace, you’ll be in no big rush to find the finish line. The course features a mix of surfaces (smooth pavement, gravel and hard-packed dirt) with punchy climbs, flat out fire road and flowing natural singletrack descents. Riders will finally descend a cliff top to the shoreline with stunning coastal views.
