Lost in the Rocks and Trees claims to be Ontario's Toughest Mountain Bike Race and takes place on July 14th in Mattawa. There are 30, 62 and 110KM courses and discounts if you sign up before the deadline. There is an Opus Fhast Carbon Fibre Hardtail 29′r Frame for a giveaway, a BBQ and all proceeds go to support trail development and other riding initiatives. Fantastic!
