Event overview

Set in southern Finland’s Salpausselkä UNESCO Global Geopark, this trail experience winds through tranquil forests, past mirror-like lakes beneath the midnight sun, inviting you to reconnect with raw Nordic wilderness.

A land carved out of water, the incredible terrain was formed by the melt waters of the continental glacier some 12,000 years ago. The land of a thousand lakes and the midnight sun, its tranquil forests offer an amazing location for trail running and reconnecting with nature.

Choose distances from approachable 25km routes to epic 110km adventures, each fully marked with support and camaraderie along the way. It’s endurance running reimagined among stunning natural beauty.

Highlights

  • Breathtaking terrain shaped by ancient glacial waters, with forests and lakes at every turn
  • Five distance options from 25km to 110km, welcoming runners and walkers alike
  • Courses recognised with UTMB® Index status for selected distances

Truly an incredible experience. Finland is such a stunning country in particular Lahti where the race starts and finishes. The route was extraordinary through the forests leading to picturesque scenery of lakes was stunning! All the crew were lovely and so encouraging and you felt supported throughout. The community of runners was to be felt from before the start and continued after the race- a truly magical experience with lovely like-minded people, friendships were made. I would come back and race again and encourage anyone thinking about signing up for this race to DO IT! Finland and ULTRA X will not disappoint. Hayley D

I’d never really thought of going to Finland before I signed up, but I will definitely be going back. It feels like you’ve stepped straight into a fairytale! You don’t have to go far before you’re in beautiful forests that touch the sky and open up onto clear blue lakes. Everywhere you look has a breathtaking view. I can’t wait to explore more of Finland, definitely one to add to your bucket list. Holly B

A great weekend away exploring a new country! Lush runnable forest trails and a few especially beautiful spots on the course by the lakes. Wholesome vibes as with all Ultra X races and great to meet many first time ultra runners! Rahil Sachak- Patwa
