Swat the black flies and tackle carriage roads, single track and a river crossing in this trail running race that's 100% New Hampshire. Solo and relay categories.

This hillclimb will be contested on exactly the same course as the historic Mt Washington Auto Road Bicycle Hillclimb – the toughest hillclimb in the world. This new addition is in response to the overwhelming popularity of the MWARBH and this year will benefit the Mt Washington Observatory and other non-profits. The intent of this second hillclimb is to satisfy the demand for bicycle racing on this hill and to raise money, but it will only be conducted in a way that will not hinder the Tin Mountain Conservation Center's ability to raise funds in the future through the annual Mt Washington Auto Road Bicycle Hillclimb held in August.  Auto Road will be open to the public from 12:30 pm until 6:00 pm.

Join us at Great Glen Trails Outdoor Center when the cannon fires to signal the start of the annual mountain bike race. For 24 hours, riders will take on the racecourse for this challenging and grueling event. Spectators are encouraged to come cheer on the racers and enjoy the festivities under the event tent.

You may have seen these bicycle racers on TV challenging mountains in Europe, but they call this event the "TOUGHEST HILLCLIMB RACE IN THE WORLD!" 7.6 miles up the Mt. Washington Auto Road. Come see for yourself why the top racers from around the world and local riders travel to Pinkham Notch to challenge the Mt. Washington Auto Road. Auto Road open to the public from 12:30 pm until 6:00 pm.
