Seabrook Lucky Trail Marathon Weekend

Seabrook Lucky Trail Marathon Weekend runs from March 12 to 14, 2027, in Seabrook. Friday evening opens with a kids 1K at 5:15 p.m. and a 5K at 5:30 p.m. Saturday brings the marathon (26.2 miles) at 7:15 a.m. and a half marathon (13.1 miles) at 7:30 a.m. Sunday adds a second half marathon at 7:15 a.m., a quarter marathon of about 6.5 miles at 7:30 a.m. and another 5K at 7:30 a.m.

Everything is run on trail, so expect softer footing and slower splits than a road equivalent. The weekend format is the draw: you can pick one distance, or double up on the Saturday and Sunday halves for back-to-back long efforts. If you are aiming at the marathon, train on unpaved ground and build a weekly long run out past 18 miles rather than chasing pace on the track.
