Cape Town - Attention in the Southern hemisphere may be on the Rugby Championship right now, but Northern hemisphere giants England and Wales have been hard at work as they prepare for this year's Rugby World Cup in September and October.
The Allblacks.com website reports that Wales have been at a camp in Doha, Qatar where they have trained in heat exceeding 40 degrees Celcius.
Welsh wing George North was quoted by the website as calling the conditions "savage".
The players are also going altitude training, sleeping in chambers that can replicate an environment that is 4500m above sea level.
England, meanwhile, have been in Denver in the United States where they were also being exposed to some high temperatures.
“Some of the training sessions have been really gruesome,” England backline and defence coach Andy Farrell said.
“We wanted to see who came out fighting in those sessions and to a man all 45 have been exceptional.”
Both nations will be in action on August 15 when Wales host Ireland in Cardiff and England host France in London.
