DTS OUDERKERK 2027 – NEW COURSES, NEW CHALLENGES, MORE FUN!

A brand-new Middle Distance, spectacular cycling routes and beautiful new running courses. DTS Ouderkerk is taking things to the next level in 2027!

With its lovely sandy beach, spacious green surroundings and beautiful countryside roads, the Ouderkerkerplas is the perfect setting for an unforgettable triathlon experience!

And this year, we've got some exciting news! For the very first time, we're introducing the Middle Distance (1.9 km swim – 90 km bike – 21.1 km run). After swimming in the beautiful Ouderkerkerplas, you'll head out on a stunning 45 km cycling loop, taking you past picturesque places such as Vinkeveen, Waverveen and the famous Ronde Hoep. Complete this loop twice before taking on our fantastic new 21.1 km running course!

But there's more! Our Olympic Distance and Sprint athletes will also enjoy brand-new running courses, making DTS Ouderkerk 2027 an even more exciting experience for everyone.

Three distances. Beautiful Dutch scenery. New courses. And that unbeatable DTS atmosphere!



Get ready to swim, bike, run and enjoy every moment at DTS Ouderkerk 2027!

MIDDLE DISTANCE

Olympic & Sprint distance

swimming

We swim in the “large” lake and start from the water (water start). This lake is nice and deep, so there is little to no chance of blue-green algae at very high temperatures. The Sprint swims one lap of 750 meters and the Olympic Distance swimmers swim two laps.

CYCLING

If we are able to use the viaducts due to A9 roadworks, we have a long 10km cycling loop, with the Sprint completing 2 laps and the OD 4 laps. We usually only know this shortly before the race. Should we be unable to cycle under the motorway, we will do the 5km loop around the lake: 4 times for the Sprint and 8 times for the OD.

RUNNING

You run along the partially unpaved walking path around the lake. The course can be described as technical, with lots of twists and turns. But it is a fabulously beautiful run with an idyllic, super-long jetty at the end that you run across to cross the lake. For the Olympic distance, you complete two of these laps.
