2026 New Hampshire Marathon, Half Marathon and 10K

The New Hampshire Marathon is a fall race series held in Bristol, New Hampshire, offering a marathon, half marathon, 10K, and a free Kids Race. The marathon and 10K begin on Lake Street, outside Newfound Memorial Middle School. Half marathon participants start at Sculptured Rocks in Groton. This event, established in 1993, attracts over 500 participants across all its races. The marathon route encircles Newfound Lake during the peak fall foliage season. Runners will encounter lake roads, classic New Hampshire small towns, and autumn colors, deviating from a typical urban course. Participants come from over 45 states and 10 countries, indicating a broad reach beyond the local region. Since 1995, the race has contributed over $300,000 to local youth charities. The finish line is located in Kelley Park, featuring a performance by Carroll Brown, The Solitary Man, for incoming runners.
