Tiirismaa Trail 8 km - at XX:XX - NEW ROUTE
The 8 km of Tiirismaa has been completely renovated, and now the route has been made easier in terms of climb. This is a route that is well suited for first-time trail runners. Young people under the age of 16 also compete on the same route, for many perhaps their very first trail event. The renovated route heading towards Tapanila runs partly in the same landscapes as the Tiirismaa Winter Trail, but mainly on different trails. The route heading towards Tapanila starts immediately with technical trails and the stunning shoreline scenery of Lake Vesijärvi. The approximately 3 km stretch of beach is completely exceptional in Finnish trail running – rarely do trails run so spectacularly right next to the water. From the beach, there is a long climb towards the highest point in Lahti. The 8 km is suitable for those who want their first trail experience or want to come and enjoy the atmosphere of the event, even with a group of friends. There is one (1) service point along the route.
The second most popular route on the Tiirismaa Trail has been the 12 km route over the years, which offers an intense challenge with a climb profile that is enough to challenge even the most experienced runner. The route heading towards Tiirismaa includes all the essential climbs and descents – tough trail running without any unnecessary sections. This route is especially suitable for those who want a challenge in a concise package or are taking their first steps towards longer and more demanding trail events. The schedule also allows for family participation: 8 km and 16 km routes will be run in the morning, and 12 km in the afternoon. There are two (2) service points along the route.
Tiirismaa Trail 16 km - at XX:XX - NEW
Our new 16 km route offers a lighter option between the 12 km and 21 km hill routes. The route heading towards the Tapanila terrain starts immediately with technical trails and the magnificent shoreline scenery of Lake Vesijärvi. The approximately 3 km stretch of the beach is completely exceptional in Finnish trail running – rarely do trails run so spectacularly right next to the water. From the beach, there is a long climb towards the highest point in Lahti, after which the route continues on fast-paced, winding and hilly small trails. The schedule also allows for family participation: in the morning we run 8 km and 16 km distances, in the afternoon 12 km – nothing more than negotiations at home. There are 2 service points along the route.
Tiirismaa Trail 21 km - at xx:xx
Tiirismaa Trail 21 km is a journey that can be called a journey with good reason. Finland's toughest half marathon trail. This route has not spared a single moment of ascent – the path takes the runner from almost every possible direction to the highest points of Tiirismaa and Messilä, time and again. Every kilometer feels like it, but the reward for the effort is the occasional breathtaking views of Lake Vesijärvi and the peaceful backcountry of Iso Tiilijärvi. In 2025, this legendary 21 km already collected 200 participants, and its reputation is growing for a reason: Tiirismaa Trail 21 km is not just a run, it is the closest thing to a mountain test you can get in Southern Finland's trail events. 2 service points and 1 drinking place along the route

Tiirismaa Trail 42 km - at XX:XX - NEW ROUTE
The new single-lap 42 km route of the Tiirismaa Trail trail marathon takes runners into the unique nature of Salpausselkä Geopark – a place where the ice age stopped about 12,000 years ago, leaving behind magnificent waterways, steep cliffs and rugged terrain. Despite its flatness, the beginning of the route will not leave anyone cold. The exceptional 3 km stretch of shoreline on the shores of Lake Vesijärvi offers variety, beautiful scenery and the most technical trails in the area. On the Tiirismaa side, you will experience an exceptionally demanding amount of climbing and technical trail running: the curly little trails require precise walking and rhythm control.

Tiirismaa Trail Ultra 63 km - 7:00 AM - NEW
The 63 km of Tiirismaa Trail is the toughest endurance challenge of the event. This ultra-distance combines one lap of the 42 km trail marathon and the most demanding 21 km section of Tiirismaa, and takes the whole thing to a whole new level. If 42 km is not enough, 63 km offers more of everything: more climbing, more technical trail and longer continuous exertion on the slopes of Tiirismaa. The route is exceptionally tough and the climbing meters accumulate mercilessly, making this trip one of the most challenging trail ultras in Southern Finland. The 12-hour time limit ensures that reaching the finish line requires both strong legs and a strong mind. This is not just a trip – this is a test where you really conquer the highest points of Southern Finland.
