Race the Cog
Mount Washington, United States • 13 Sep 2026
Race The Cog : Bretton Woods, NH
Race The Cog is a mountain running event organized by Aravaipa Running that was postponed from June 27, 2026 to September 13, 2026. The course follows the Mount Washington Cog Railway alignment from the Marshfield base station to the summit of Mount Washington.
The Summit Climb covers about 2.75 miles with approximately 3,500 feet of total climbing and more than 1,000 feet of climbing per mile. The route begins on dirt and gravel, becomes steeper and rockier near Jacobs Ladder, and continues through large boulder fields to the summit alongside the Cog Railway. Weather on course can vary widely between the base and summit, including strong winds and mixed temperatures. Summit finishers receive a bracelet that serves as their ticket for a train ride down from the summit; trains run hourly and have a one hour layover at the summit. No participant bags are transported to the summit.
The Devil's Shingle Roundtripper option tags the summit at mile 2.75 and returns by foot for a 5.5 mile roundtrip that finishes at the start. Aid stations are located at Waumbek Station (0.9 miles) and the summit (2.75 miles) and offer water, electrolytes, soda, snacks, and fresh fruit. The event is cupless so participants must bring their own hydration system.
Prize money includes a $1,000 award from Delta Dental for anyone who beats the elite wave train. The event is part of the Delta Dental Mountain Challenge series. Post race food and music are provided at the base station. Visit the organization's website for the most recent information.
