About the Forssa Summer Night Marathon
Forssan Suvi-ilta has gathered competitive runners and recreational participants in midsummer since the early 1990s. The marathon is the event's full-distance road race, using the clear English identity Forssa Summer Night Marathon.
Course
The measured marathon uses two laps on roads through Forssa and neighboring Tammela. Its fast profile and afternoon start send runners through both circuits in Finland's long summer daylight.
Race-day weather
Midsummer in southern Finland is often mild with abundant daylight, but an afternoon start can feel warmer than an early race. Rain, breeze, or cool air are still possible, so conditions may shift across two laps.
