Get ready to take flight at the Aviation Museum of New Hampshire's Run the Rail Trail 4 Miler on Saturday, May 2, 2026, in Londonderry, NH. This annual 4-mile run/walk event, now in its fifth year, offers a unique opportunity to experience a scenic course that starts and finishes at the Aviation Museum's historic 1937 terminal building, located adjacent to the Manchester-Boston Regional Airport runway.

The course is entirely on paved roads, winding through the lightly-trafficked streets and historic village area of North Londonderry. A highlight of the route is a 1.2-mile stretch along the recently opened Londonderry Rail Trail, which guides participants through the tranquil Little Cohas Brook Reservoir area. Runners should be prepared for a significant elevation rise in the first mile, followed by an equally steep descent. Two water stops are available along the route to keep you hydrated. Typical race day conditions in early May feature comfortable highs around 66F and lows around 41F, with only a 15% chance of precipitation, offering ideal weather for a spring race.

More than just a race, the Aviation Museum of New Hampshire's Run the Rail Trail 4 Miler is a fundraiser dedicated to supporting the museum's youth education programs, which include summer camps and student plane-building projects. Runners and walkers of all ages are welcome to join this event, though strollers and pets are not recommended due to the course's elevation changes. Join this growing race, which saw a record 166 participants in 2025, for a memorable experience that combines a rewarding run with a meaningful cause.
