Rocky Mountain States Hillclimb Association, RMSHA, today released its 2025 Race Schedule featuring eight stops across Idaho, Wyoming, Colorado, and Utah, presented by onX Offroad.
Often referred to as "RIM-SHAW," RMSHA is the country’s largest and longest-running snowmobile hillclimb association. Its multi-venue, adrenaline pumping hillclimb snowmobile series showcases amateurs, pros, and junior racers as they test their skills against gravity as powerful snow machines propel them skyward.
“We’re excited to have onX Offroad return as our presenting sponsor for the 2025 season, said RMSHA President Cody Spencer. The app aids the RMSHA organizers in designing the course, spectator zones and ensuring safe but exciting races each weekend. Throughout the season, OnX Offroad is the preeminent snowmobile tool for racers and all riders with thousands of miles of snowmobile trails and backcountry snow safety tools, which makes them a great partner for our Association.”
