Riders have the option to select from 20K, 40K, 60K, or 80K routes that highlight the stunning gravel roads and paths of Lambton County. All routes kick off and wrap up at the Legacy Recreation Centre situated in Thedford, Ontario. This event embraces a non-competitive spirit, encouraging riders to fully enjoy the experience. Participants are welcome to pause at designated fuel stations, regroup, and connect with friends and fellow cyclists. Each distance comes with an array of benefits: all participants will receive event jerseys, a swag bag, bike assistance throughout the ride, well-marked routes, complimentary food and drinks at the finish line, and the option to purchase beer. To participate, riders must be at least 15 years of age. Registration is now open for the 3rd annual BIG Gravel Grind—don’t miss your chance to be part of this exciting ride! New for 2026, we're excited to offer four route options: 20K, 40K, 60K, and 80K to suit every rider.
