 We've been looking at altitude training. Now, for altitude training it's a couple of things. People struggle when they go to altitude. If you go up to, say, Mt Cook, for instance, or go to somewhere like Colorado, you'll find that you breathe quite heavily for the first wee while and you maybe get a little bit dizzy. So that's the effect of altitude on the body. And if you have to exercise, for instance, in altitude, it becomes quite hard for some people. So we try and acclimatise them to altitude so we can do that by getting them to breathe a low oxygen air before they go there, or perhaps go to altitude before they go there and train at altitude. So that's one area. And the other way we look at it and it's quite new is using the same sort of principle but having persons stay at low level and get them to train at altitude. So they're breathing low oxygen air through tubes and we're getting them to train so that when they perform, they perform better. You can get that stress if you've got a lot of money by going overseas to very high altitudes but a lot of New Zealand athletes don't have that money so we have to figure out ways in which we can help them get the same stress at a lower cost. It's one of the things that you can experience yourself. So when I went to St Merritt's, I was following the Netherlands triathlon team with John Hallamins and when I got up there, you can definitely feel how it would affect you even though I wasn't doing much of the exercise.
