YEs, dummy. They are going down to the Southern Hemisphere in the Winter because of.....altitude? They are going there because it's warm and dry, unlike their home bases in England.
Err, yes. Potch, which is not generally considered high enough to give the true benefits of altitude training, has long been popular with sprinters and middle distance athletes from all over the world because of the guaranteed weather, facilities and cheap cost of accommodation and food.
how many testers are chasing athletes down in South Africa, Kenya, Ethiopia, and other Brit training favorites?
