Whites 100

About the Event

Whites 100 returns to Shelburne, New Hampshire on September 11th for another year of endurance challenge tailored specifically for trail runners aiming to complete the massive WM 100 route. This event offers logistical support through access to five drop bags and transportation services throughout the course, ensuring participants can focus solely on their journey.
The setting in Shelburne is a blend of rural tranquility and challenging terrain. On race morning, when temperatures are typically mild with firm trail conditions underfoot, runners will find themselves amidst natural beauty that provides both solace and challenge as they traverse miles through varied landscapes. The trail conditions here mean the ground offers enough stability without being overly hard on feet after long hours of running.
Whites 100 is an established event in the local endurance community, drawing participants who are dedicated to testing their limits over a full day or more across rugged terrain. Participants contribute by purchasing a drop bag for $200, which covers transportation and logistical support throughout; this bin fee supports trail maintenance efforts locally unless reclaimed post-event at no cost less than the initial investment in gear provided.
The course of Whites 100 winds through trails that are known for their challenging yet rewarding scenery. Participants start along US-2 before delving into a series of rugged paths where drop bags and transportation points serve as crucial rest stops, providing much-needed respite from the rigors of continuous movement over such distances. The terrain varies widely but is generally firm enough to maintain traction without undue wear on shoes or joints.
Weather conditions in Shelburne during September often feature moderate UV exposure with a typical index around 5.0 (considered Moderate). This means runners should expect clear skies and comfortable temperatures, though they may need protection from the sun’s rays as part of their preparation. Humidity tends to be low at this time of year, making for generally pleasant running conditions but still requiring adequate hydration.

All runners must bring a Garmin InReach device to ensure they can utilize drop stations effectively throughout their journey.
The starting point for Whites 100 is located along US-2, where participants should gather with all required gear including the aforementioned communication devices as well as personal provisions suitable for multi-day endurance running on trails in Shelburne.
