Centre Jamie Roberts and defence coach Andy Farrell have insisted that the Lions will have no trouble coping with the searing Hong Kong heat in their tour opener against the Barbarians on Saturday.
There will be two drinks opportunities in each half to counter the threat of players over-heating because of night time temperatures expected to be in the late 20s Celsius.
But Roberts, well aware of the potential dangers given his medical knowledge, made light of the draining conditions.
“Training has been tough and we have trained at an intensity to make it tough,” said Roberts.
“It’s the same for both sides but lots of players won’t be used to these conditions. It’s a bit like Cardiff or Barry Island in the summer!
“Look, it will be demanding and we do need drinks breaks from a health and safety perspective as well as for the sake of the quality of the rugby.”
Farrell meanwhile is adamant that the physical shape of the Lions squad will stand them in good stead.
“The boys fill in wellness charts every morning and have their urine tested before and after each training session,” said the former rugby league man.
“The first day we trained here it was about 85% humidity and some of the boys lost three to four kilos.
“But the next day we had re-hydration breaks and fans at the side of the pitch and some only lost a kilo.
“We think we have it all covered.
“The lads have ice vests if they want to use them which they can put on at half-time to bring their temperature down.
“But one thing that shines out to me is the great physical these guys are in.
“We have been able to train them to a level above match intensity and in the game they will be thinking about rugby not heat and exhaution.
“Hopefully we will be able to play at an intensity the Barbarians will struggle to cope with.”
Roberts meanwhile admitted he cannot wait for kick-off on Saturday.
“We have trained for three weeks and just want to play rugby now,” he said.
“We have prepared well but it’s important we now set a standard for the guys to raise the bar afterwards. That’s what we did in 2009 when we never allowed our standards to drop below the level of the previous game.”
The Lions have no fresh injury worries following Sam Warburton’s withdrawal from the Barbarians match with a knee injury.
