Hidden Handup! We are super stoked to have Handup Gloves on board as a sponsor of The Grindstone. Thanks to their support, we will be running a “Hidden Handup” feature during the ride. On each course, there will be a pair of gloves stashed away somewhere. The first rider to find them gets to keep themselves an awesome new pair of Handups! It’s finders keepers, gravel grinder style!
