Course & Elevation
The Björn Borg Helsinki Marathon is a single-loop road marathon in central Helsinki, held on a Saturday in late August. It is organised by Helsinki Marathon Oy, a company set up in 2017 by the event organiser Runner's High together with the organisers of the Helsinki Half Marathon, and the first race was held on 25 August 2018. The event area, start and finish are in Meripuisto, a seafront park off Merikatu in the south of the city. The marathon route combines city streets, waterfront stretches and fast running lanes in the east and north of the city before returning to Meripuisto. A half marathon is also run as a single loop from and to Meripuisto, while the 10 km starts at Kaisaniemenranta and finishes in Meripuisto, and a marathon relay of four runners covers 4 x 10.55 km. In 2026 the half marathon started at 08:10 and the marathon at 08:45. The race was created after the older Helsinki City Marathon, which had been run in August, was moved to May from 2018; the two events are separate. In 2026 Matti Jonkka won the men's marathon in 2:29:34 and Maria Elisa Legelli the women's in 2:48:54.
