Alistair and Jonny Brownlee have just faced their greatest challenge ever – forget going 70.3, forget Olympics, forget SPOTY – the real question is ‘who is the fastest down a waterslide?’


Joined by professional triathlete and rising star Lucy Charles and Olympic open-water swimmer Jack Burnell, the group were put through their paces with a number of challenges at Alton Towers Water Park.

The athletes took an initial timed run down the slide, before being given the chance to spend £50 each to upgrade their HUUB products to increase their overall speed.
