Rose Mountain Rumble 2026

The Rose Mountain Rumble, held in late August, is a gravel cycling event in Lyndeborough, New Hampshire. Starting at the Piscataquog Land Conservancy Center Hall, it provides four route lengths: 40.2 km, 72.4 km, 106.2 km, and 128.7 km. These options allow participants to select a shorter gravel ride or a longer day on their bikes. The Piscataquog Land Conservancy organizes the event, with proceeds benefiting local conservation efforts in Lyndeborough and surrounding communities. The name references Rose Mountain, grounding the ride in a specific local identity. The event is designed for cyclists seeking rural New Hampshire roads combined with a conservation mission.
