RACE INFORMATION
Curious about what to expect during DTS AMSTERDAMSE BOS 2025? You will receive the extended version of the participant information in the week before the event. Read some practical information below!
ADDRESS
This year, 2025, we are moving, due to renovation work on the Bosbaan, to the middle of the Amsterdamse Bos. That is why the name changes to DTS AMSTERDAMSE BOS.
The event site is only 1 KM from the original Bosbaan site. Parking is available on the Duizendmeterweg at the Kleine Speelweide and there are a number of other parking lots along the Bosbaanweg. Our event crew and traffic controllers will give you directions on where to park.
The event site is located on the Grote Speelweide, in the middle of the beautiful Amsterdamse Bos. There is a new swimming location, a new cycling trail and also a completely new running trail.
STARTING CERTIFICATE
You can collect your starting ticket on the day of the competition at the registration desk on the event site near the Finish.
You will receive a package from us with all the necessary supplies such as the BIB number, sticker sheet, swim cap, timing chip and, if you ordered and paid for it yourself, your finisher shirt, lock lace laces and/or start number strap.
THE DISTANCE
Saturday September 27, 2025
NEW LOCATION!
SPRINT & OD
Thanks to the new cycling course with a lap of 8 KM, we can organize an Olympic Distance at this location again, in addition to the Sprint!
The Sprint distance is a great experience and a very cool race for both the novice and the more trained triathlete!
The fast and beautiful course, right through the Amsterdam Forest, also provides a challenging Olympic Distance race
- Sprint: 750 m swim, 24 km bike, 5 km run
- Olympic: 1500 m swimming, 40 km cycling, 10 km running
WETSUIT RENTAL
Don't have a wetsuit? No problem!
Participants in DTS competitions can rent these. Order and pay during your registration.
- Wetsuit Rental Price = €55. Wetsuit will be sent to your home address by Dare2Tri (not by us) approximately 10-14 days before the race. There is a return label with which you can return the wetsuit yourself after the race for free. Wetsuits cannot be returned to DTS.
From the 2025 season onwards, we will no longer have a permanent bicycle rental partner and can therefore no longer offer rental bicycles.
