MAY 2021

Welcome to EX20

Cold water + technical trail = Xperience Swimrun!

A spectacular course over 23km with technical and hard trail combined with over 20% cold swim. A prefect challenge if you are not afraid of a tough Swimrun early in the season. 


It is our ambition to develop and reinvent the sport and we have already launched several world firsts.

First - SPRING & FALL Edition of EX

We offer you a chance to measure your development during a swimrun season with a FALL and SPRING edition along the same course. Five months seperate the two races. Start and finish your season with EX!

World first - ARK Supersprint Invitational

 As the first race in the world we have launched a Supersprint in Swimrun. An extremely fast and intense race with head-to-head elimination heats in order to crown the world's first Supersprint champions.

World first - Swimrun pursuit!

To maximize the experience EX20 will host the world's first ever Swimrun pursuit. All teams will be seeded and start with regular intervalls. The expected fastest teams will start last and can begin the pursuit of the teams ahead. Game on!

First - Falcon Mountain Base Jump by Dewalt

Before the final swim section we challenge all participants to jump 6m from Falcon Mountain. If you do not want to jump you can choose "chicken line", 75m longer with 0m jump. Dewalt will sponsor a launch ramp and awesome prizes.

First - Sleeve is the new bib

Instead of traditional bibs we will offer all participants total freedom and moverability with our brand new sleeves. Transitions will be faster than ever!


ARK Supersprint Invitational

An extremely short course where the tempo will be brutal. The race will consist of several head-to-head elimination heats to crown the world's first ever Supersprint Champions. 


A selected few have been offered the chance to participate in the inaugural Supersprint. On the starting line we already have legends like Annika Ericsson, Fredrik Axegård, Simon Börjesson, Marika Wagner and many many more.
