Jenson Button vs the Brownlees at the GSK Human Performance Lab

McLaren Honda driver and triathlon devotee Jenson Button recently took on one of the toughest challenges of his career - a head to head test with Alistair and Jonathan Brownlee.
Button, who trains and regularly competes in triathlons to stay fit for F1, was put through his paces in the GSK Human Performance Lab in a series of triathlon and F1 tests to compare and contrast his physiological and cognitive performance with the Brownlee brothers.
Using GSK HPL cutting edge science, Jenson and the Brownlees went head to head in a series of swimming, cycling and cognition tests under strict laboratory conditions. The group also underwent skin and core temperature tests to assess how their bodies perform in the heat and humidity Jenson is likely to experience in the Singapore GP (35˚C and 70% relative humidity). The tests will help Jenson understand where he can improve in triathlon, and help the Brownlees acclimatise to the heat and humidity they are likely to experience in Rio 2016.
