Renowned for its incredible crowd support, Garmin Challenge Herning on 11 June is the must-do triathlon of the summer. The fast, flat course through iconic Danish countryside is created for speed and even a new personal best! And you are never alone as the crowd of thousands carries you through to the famous finish line party right in the heart of historic Herning.

SWIM – 1.9KM


The swim takes place in Fuglsang Sø, known for its clear and always calm water, with great spectator viewpoints. The long straights make for easy sighting and fast times.

The one-lap bike has plenty of long straights and no 180 degree turns and is fast and flat through the stunning landscapes and typical Danish villages that surround Herning.

Last but not least you will feel the Danish crowd’s love for triathlon from your very first steps on the four-lap run course – the only one in the world that goes through a library!

You’ll hear the finish line before you see it! And in true Challenge style, you can share this very special celebration with those who matter most.

Herning as a town was great and the support (particularly  on the run) was excellent. A good course for a PB (which I achieved) and an amazing GB experience.

I’m a bit of a slowbie so I finished later on in the day, but you wouldn’t have thought that, the finish chute was packed out and the support was amazing, it was one of the best finishes.

Brilliantly organised, brilliantly marshalled and refereed and fantastic atmosphere. Would highly recommend.
