Course & Elevation
The Helsinki Half Marathon is a road race through central Helsinki, held on a Saturday in early or mid June, with a 5 km run on the same morning. It is Finland's second biggest half marathon, and the organisers started it in 2014 to create a fast, scenic course in the city centre. The start and finish area is in Meripuisto, a seafront park, with both at the same place on Ehrenströmintie, so the race is a loop back to the start. In 2026 the half marathon started at 8:30 and the 5 km at 8:45. The 2026 half marathon route passed Katajanokka, Suvilahti, Vallila, the north end of Töölönlahti and the south end of the Baana, with five hydration stations. The route for each year is announced closer to the event. The time limit is 3 hours 10 minutes for the half marathon and 1 hour 5 minutes for the 5 km. The title sponsor changes: the race was run as the BMW Helsinki Half Marathon in 2024 and 2025 and as the Björn Borg Helsinki Half Marathon in 2026.
