I've actually never heard of trying to adapt from high altitude to low altitude. Of course I've heard a lot about going from low to high. I live in Denver(1 mile above sea level) and therefore have a good deal of experience with altitude. I'd be interested to hear about any info. you may find about this.

Your body will need about at least 10-15 days to get used in a lower level than it was before.

Hello Everybody, than you very much for your valuable answers. I also consulted a study from the Spanish TRiathlon Federation and the general consensus is the following: You do need to adapt to a lower elevation this is mostly because of changes in blood pressure when racing at different altitude and musuclar adaptation to the intensisty that can be carried after training at a higher altitude. So Athletes should travel 15 days before the event or only 3 days before the event. The worst time to travel is betwwen 4 and 10 days before the event, as some adaptation to altitude is lost and there is no adaptation to low elevation or sea level. It was also advised if it isn't posssible to travel 15 days in advance to try and have some workouts in the previous days to the race at a lower altitude. So we have been training at 800 m above sea level for some key interval workouts. I will let you know how it all went. We will travel 3 days in advance to a triathlon world championship.
