1st time in the height tent: A large personal record in the Amsterdam Marathon. 2nd internship in the height tent: A 7th place in the Boston Marathon.

The high altitude tent has already made a very good impression during training sessions. Unfortunately, because of the Corona, there are no races to prove my form.

Sports performance has improved. Improved 10 seconds on the 5000m. However, I see the height tent as one of the factors that helped.

Good contact, pleasant delivery times and good explanation. I used the altitude tent prior to an altitude internship in Kenya. This made acclimatization much easier.

Everything must be right on the 800 meters! I use the height tent to work on my endurance and postpone acidification.

I have experienced your service as very pleasant. The information was also complete. For my idea I have benefited greatly from the height tent, but especially 3-4 weeks after I came out of the tent. My condition really had a boost afterwards.

The effect of the height tent was clearly noticeable. After a few weeks there was a considerable improvement in the condition and this continued to work when I was actually at a great height. I did not suffer from altitude sickness during the Mount Everest Marathon. That too may be due to it

My nights were excellent. Sometimes a feeling of thirst, which makes sense given the height. It is recommended to have water in the height tent. Regulatory control of oxygen content with the saturation meter supplied by Altitude Dream. The effect was that my body for a long time (approximately

Sleeping in the height tent has improved my endurance and fitness! We also learned a lot at Altitude Dream, such as how many weeks of sleep in the height tent the effect is optimal.

The biggest effect for me was the compulsory rest in the height tent. No food either, so I clearly lost extra weight. Another effect there was even more motivation for the training and I had even more focus. Unfortunately I was unlucky with the results. First time oh so bad weather on the marathon and I ran

I thought it was super that it was possible to extend the initial rental period. Thanks!

Pick up and drop off on a Sunday, can it get any crazier? Really great. In addition, after first contact, the altitude tent in the house a few days later. Effect: I think it is very good, but unfortunately it is not really reflected in my result. Due to the heat not being able to perform optimally during the Slachtemarathon.

I call myself an ambitious recreational marathon runner who likes to make many kmers. The decision to rent a height tent came after a strong training 5 days after vacation in Switzerland, so rather "based on feeling". In absolute numbers, I ran the Berlin Marathon after the height tent period,

I have experienced the service as very good. Both the handling of e-mails and the collection and delivery of the height tent. The level I now have after sleeping in the height tent is very good and that is the reason that I purchased the system after the rental period.

I slept a maximum of 5.5 hours per night in the height tent because of my work. Restricted sleep nevertheless produced a good result. When walking at 4600 m total no problems with the height. The service was also very good. Everything as agreed and at the agreed time.

I notice a much faster recovery than last time and less fatigue. My condition is still very good!

I just came back from Nepal yesterday after successfully completing the Everest marathon. During the trek to the Everest Basecamp, my oxygen level in my blood was regularly measured. I from the low Netherlands generally had the highest value and that seems to me too

I received very good and positive explanation during the placement of the height tent. Thank you for this! The first experience with sleeping in the height tent, was very good! I have been able to develop a very strong basis, unfortunately some competition conditions that were a bit disappointing.

The altitude tent allowed me to do altitude training for about 5 weeks. With this, I am preparing for the European Championships indoor athletics in Poland. I was very satisfied with the service. Everything was carefully installed at my home, and I received extensive information on how to proceed with the

Great service! Pleasant personal contact and lots of information. The immediate effect is always difficult to measure when everything is the first time. The goal in my very first Marathon was to also directly qualify myself for the Boston Marathon to run within 3h35. And YES I succeeded!!! 3:34:05 was

I truly believe my 1st marathon turned out so well because of that increase in red blood cells. My last 10km were my fastest, where the majority are with decay. Service was also very good! If I had any questions I could always email or call them, even on Sunday and always a quick reply.
