Rob Holden, who conquered Mount Washington and Mont Ventoux within the cycle hire scheme parameters of New York and London, made his Hour attempt a week before Sir Bradley Wiggins

In October 2013, Rob Holden hired a Boris bike, took it to France, scaled Mont Ventoux and returned it to a South London docking station within 24 hours.

Not content with that, last summer he and his team – logistics man Matt Winstone and Ian Laurie behind the camera – then flew to New York, took a Citibike 400 miles to New Hampshire’s Mount Washington, went up that, brought it back and flew back to London, all in a day and a half.

Their latest stunt, though, might just have been the toughest of all.

On May 29, at the Herne Hill Velodrome, no-one would have been thinking about Sir Bradley Wiggins’s attempt at the Hour Record. This was Rob’s shot at glory on a 23kg Santander Cycle – a machine more than three times heavier than Wiggins’s Pinarello Bolide HR.

Spoiler alert – he didn’t make it. He did, though, set down an immensely creditable mark of 31.29km.

The attempt, like Ventoux, was to raise money for Macmillan Cancer Support – the ride up Mount Washington had also been in aid of Livestrong.
