The Taeru triathlon camp will immerse you in all things triathlon. You will stay in the brand-new, inspiring Taeru sports hotel. The facilities include a 25-meter swimming pool, sports hall, bike storage, professional kitchen, and relaxation areas.

Taeru is located in the center of the Ardennes which ensures beautiful – and challenging – bike trainings. Run sessions will be organised on and offroad. For intervals, we have the option to go to a nearby 400 meter track.

The training camp includes breakfast and dinner. On the non-bike day, you will also be served lunch.

Triathlon clinics

In addition to the training sessions, the tasty meals, and a lot of fun, the Taeru triathlon camp also includes three clinics. These clinics are geared to sharing knowledge, and to increase your skill level.

On Tuesday night, we’ll have a Q&A session on ‘all things triathlon’. You can ask any question, which we will try to answer as well as possible – including practical examples.

On Wednesday, we will organize two clinics. In the morning, you can participate in an endurance run during which your lactate will be measured. The value of these readings will be discussed during a Q&A session after dinner.

After lunch, you can shave precious seconds off your transitions in a clinic in which we will have you finetune your swim-to-bike and bike-to-run transition.
