Karl Dossche TriathlonAntwerp5/525-9-2016Before and during the "altitude training" I had my haematocrit determined, which eventually went from 39 (before) to 43 (after), so probably a pretty positive effect. Unfortunately, I did not take any extra iron during this period, perhaps the effect would have been even greater. The installation of the high tent went very well, I did not have any problems during the rental period. The return of the tent was also done according to the agreement. Sleeping in the tent was not too bad, maybe I was lucky that it was not too hot outside. The most important thing of all is that I was able to qualify for the Ironman in Hawaii, which was the ultimate goal. So I will probably rent a high tent again, I think mid August to end of September, I will keep you posted.
