The roller-ski facility in that email is the Ukonniemi cross-country and biathlon area in Imatra, specifically around Ukonniemi Stadium / Ukonniemi Arena in the Rauha–Ukonniemi sports resort zone on Lake Saimaa. It’s a compact “sports-institute-style” cluster a few kilometres from Imatra city centre, with the roller-ski track, first-snow track, biathlon stadium and most accommodation all within walking distance.
The roller-ski track is a modern, competition-style loop of about 3.3 km, built in 2015 and designed specifically for summer training in ski disciplines. Its profile imitates current FIS race courses (climbs, fast descents, varied terrain) and it runs in and around Ukonniemi Stadium, also forming the base for the First Snow Ski Track once they put stored snow on it in October. The stadium/arena and first-snow track starting point, parking and customer service are all at Ottelukatu 11, 55420 Imatra, which is basically “where the facility lives”.
