Back again for 2025 is the Greystone Gravel Grinder, in support of the Huntsville Mountain Bike Association (HMBA).
We are partnering with Greystone Project Management, The Bikes Shop Huntsville, Muskoka Bicycle Proshop, Threshold Coffee and the Huntsville Mountain Bike Association (HMBA) to deliver this annual early-season fundraising event for the HMBA. The funds raised from this event have already been converted into an impressive amount of trail development.
