The Vermont 100 Endurance Race stands out as one of the pioneering 100-mile runs in the U.S. and is included in the Grand Slam Series of Ultrarunning. Every year, around 300 competitors take on this challenging course, which requires them to navigate a hilly terrain with a total elevation gain of 17,000 feet within a 30-hour timeframe, with the elite few aiming for a sub-24-hour finish. Runners will traverse scenic country roads, lush forest trails, and witness stunning vistas of the southern Green Mountains, as they face the relentless ups and downs of the course. The combination of its breathtaking landscape and demanding elevation changes makes the Vermont 100 a memorable and tough challenge for ultrarunners.
