The pair, both world class climbers, will attempt to beat the previous record set by Yuji Hirayama and Hans Florine. The record time, an astonishing 2:37, was set back in 2008.

On their first 'training run', just hours after meeting for the first time, Honnold and Steck climbed the route in 4:40 and the following day they climbed it in 4:20.

"We met each other for the first time at the El Cap Meadows. Alex is full of beans. If I would not know what he has already climbed in his life, I would think he is a normal, motivated climber. Alex is 24 years old and has climbed the most wildest things." commented Ueli on his blog.

The video below shows Honnold and Steck doing the King Swing pendulum. The climbers to the left are on the Jardine Traverse, which avoids the King Swing and is a popular variation.
