38. Terwamarathon Oulu

The Terwamaraton, also known as Terwahölkkä ja -maraton, takes place on Saturday, May 23, 2026, in Oulu, Finland, featuring beautiful routes along picturesque waterfront promenades ([terwamaraton.fi](https://www.terwamaraton.fi/?utm_source=openai)). The race was first established in 1989 as the Oulu Marathon and has been held under its current name since 2002 – back then with only about 300 participants, today the number of participants has grown to around 2,000 ([ahotu.com](https://www.ahotu.com/event/terwa-marathon?utm_source=openai)). Typically, about 500 runners tackle the full marathon distance (42.2 km), while around 1,500 participate in the shorter distances such as half marathon, 10 km, and children's run ([ahotu.com](https://www.ahotu.com/event/terwa-marathon?utm_source=openai)).

The course is known for its flat and fast profile: marathon runners complete two laps of 21.1 km each. The elevation difference of the loop is only about 16 meters, creating ideal conditions for personal best times or marathon debuts ([ahotu.com](https://www.ahotu.com/event/terwa-marathon?utm_source=openai)). The start and finish are located near the Oulun Stadion, and the route runs on paved foot and bike paths along the water – very scenic and also easy to manage ([ahotu.com](https://www.ahotu.com/event/terwa-marathon?utm_source=openai)). The measurement is conducted by an AIMS-certified course measurer, ensuring official and precise timing.
