Spring marathon season is nearly here, and 2026 is shaping up to be one of the most competitive years in recent memory. From the cobblestones of Boston to the flat speed of London, here’s your guide to the major races coming up this spring.
Boston Marathon – April 21, 2026
The world’s oldest annual marathon returns for its 130th running. Boston remains the only major that requires qualification times, making every finisher’s bib a badge of honor.
Course: Point-to-point from Hopkinton to Boston, 26.2 miles with significant elevation changes including the infamous Heartbreak Hill at mile 20.
What to Watch: The men’s field is stacked with defending champion Evans Chebet returning alongside Eliud Kipchoge, who’s targeting his first Boston title. On the women’s side, Hellen Obiri aims to defend her crown against a deep field of challengers.
Weather Factor: Boston’s unpredictable April weather can make or break performances. Runners have faced everything from snow to extreme heat on Patriots’ Day.
London Marathon – April 27, 2026
Six days after Boston, the world’s fastest runners descend on London for what’s consistently the deepest field of the spring marathon season.
Course: Flat and fast, starting in Greenwich and finishing on The Mall near Buckingham Palace. Known for producing world records and blazing fast times.

Rotterdam Marathon – April 13, 2026
Rotterdam has earned its reputation as one of the fastest marathon courses in the world, second only to perhaps Valencia in terms of pure speed potential.
