If you want to give an extra shoot for your training, and try the effects of altitude training, you have the possibility to do this on NextLevelCamp.
Remember around the altitude training, that it should be done at least over one months period, to get out some positive benefits…and if you want to do this, it is important that you send an email well in advance for us, to hear if the tent is free
Craig Alexander was using altitude tent last year in US, with some great effect and benefits, and got some good help and advise from Frank , check here:
