With a pleasant sandy beach, a large grassy area, and the beautiful, quiet roads in the surrounding area, the Ouderkerkerplas is an ideal location for a beautiful triathlon. You swim in the 'large' lake and cycle and run around it. Currently, extensive work is being carried out on the A9, which may affect our cycling course. Therefore, there are two cycling course options, and we will only know shortly before the race whether or not we can cycle under the A9.

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.

misuse

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.

To walk

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.

Don't have a wetsuit? No problem!

Participants in DTS competitions can rent these. Order and pay during your registration.

Wetsuit Rental Price = €55. The wetsuit will be sent to your home address by Dare2Tri (not by us) approximately 10-14 days before the race. A return label is included so you can return the wetsuit yourself free of charge after the race. Wetsuits cannot be dropped off at DTS.

On Thursday before DTS OUDERKERK, we will carry out an initial measurement of the water temperature.

As soon as this is known, we will post it on our Facebook and Instagram. The rules for wearing a wetsuit:

• Temperature below 16 degrees: wetsuit mandatory
• Temperature between 16 and 23 degrees: wetsuit not mandatory, but permitted. Between 16 and 20 degrees, it is recommended to wear a wetsuit.
• Temperature above 23 degrees: wetsuit prohibited

It is possible to rent a wetsuit when registering. Already registered but still need a wetsuit? No problem! Up to 14 days before the start of the event, you can log in to your Mylaps environment and rent a wetsuit.
