THE LUNG CAPACITIES of the Irish squad were pushed to the limit at Newlands last weekend, but the forthcoming Test at altitude in Johannesburg will be on another level, literally.
Located 1,800 metres above sea level, Ellis Park is officially the highest international rugby ground in the world.
It will be a new experience for the majority of Joe Schmidt’s men although Mike Ross could offer a bit of insight into the testing low-oxygen conditions that playing on the Highveld demands.
“I’ve done some research on it,” said the Leinster tighthead.
“I’ve trained at altitude when I was in a tent and it was one of the most horrific things I’ve ever done.
“Leinster got an altitude tent for pre-season about two seasons ago, they dropped the oxygen down to about 13% and then you had to do about 10 minutes of very intense exercise and, honestly, your vision was going black around the edges coming out of it.”
“Johannesburg is about 1,500 hundred metres [above sea level] there so hopefully, with a week in, we’ll adjust to it.
“[The training] was on a bike or a rower. So, it was only 10 minutes but I don’t think Johannesburg is as bad as the tent.”
When Lwazi Mvovo scythed through the Irish midfield to make it 13-10 following CJ Stander’s red card it looked like it would be a long night for the visitors.
A rallying call from Rory Best, however, set the tone for an incredible Irish effort for the next hour of play.
“So, we just hung in there and Paddy kicked really. The backs played phenomenally well and Conor Murray got a great try. We didn’t go into our shells, we kept chasing it and I think that was the difference.”
Defending for almost an hour with 14 men may prove the perfect preparation for the crunch second Test with the Boks this weekend.
