Danmarks koldeste Triathlon

Dive into the ultimate test of endurance and cold tolerance with Denmark's Coldest Triathlon. On January 16, 2027, participants will embark on an epic journey that combines swimming, cycling, and running through some of the coldest conditions imaginable.
The event features a unique distance of 4:18:4 triathlon – 400 meters of open water swim, followed by 18 kilometers of intense cycling, culminating in a challenging 4-kilometer run. This course is designed to push athletes beyond their limits while offering an exhilarating challenge that combines elements of both the Ironman and winter endurance sports.
To ensure this event lives up to its name as Denmark's coldest triathlon, competitors must adhere strictly to minimalist attire throughout all three disciplines. Swimmers are allowed only shorts or swimsuits with no neoprene materials permitted for women’s options including traditional swimwear or short-shorts paired with a sports bra. Cyclists continue in the same outfit worn during swimming but must also wear gloves and a cycling helmet, along with socks that do not rise above the ankles.
This event promises an unforgettable experience where participants will face extreme cold while testing their physical limits against nature’s harshest elements.
For those seeking to challenge themselves beyond conventional triathlon norms, this unique blend of endurance sports offers a rare opportunity to push boundaries and celebrate winter in Denmark like never before.
