White Lake Ultras

About the Event

The White Lake Ultras is a festive, loop-based endurance event held on Saturday, May 2, 2026, at White Lake State Park in Tamworth, New Hampshire. Organized by Aravaipa Running, the event offers 6-hour, 12-hour, and 24-hour timed options. Runners navigate a scenic 2-mile circuit that winds through forested lakefront trails, featuring a unique blend of single-track paths, a short beach section, and paved sidewalks.

Event Format	Start Time	Course Details	Elevation Gain
24HR / 12HR / 6HR	Saturday, 7:00 AM	2-mile single-track & beach loop	~50 ft per loop

The geography of the course is characterized by the glacial Sandy terrain of the White Mountains region, providing "beach vibes" in a North Country setting. The loop is relatively flat, making it an ideal venue for runners looking to set personal distance records or for those new to ultra-endurance events. In early May, New Hampshire weather is typically crisp and unpredictable; average daytime temperatures hover around 16°C (60°F), but 24-hour participants should prepare for night temperatures that can dip toward 2°C (36°F). The event is strictly cupless to minimize environmental impact, requiring all athletes to carry their own hydration systems.

Logistically, the race headquarters is located on the lakefront beach, where a single, well-stocked aid station serves as the timing and fueling hub. Registration remains open until Monday, April 27, or until the event reaches capacity. While pacers are not permitted, the multi-duration format allows friends to register for different segments to run together. On-site camping is available for Friday and Saturday nights and can be reserved through the event store. Top performances at White Lake include Corin Kwasnik’s 2025 distance of 126 miles and Dwight Waugh’s 2024 mark of 125.4 miles, underscoring the high mileage potential of this serene, forested loop.
