Think you're quick uphill? The folks at informal competition site Strava are inviting you to prove it by zooming up Box Hill as fast as you can  – or, if sheer volume of suffering floats your boat, as many times as you can.

Strava's Box Hill Beat the Best Challenge runs from July 21 to August 4 and will reward the three fastest men and women up the iconic Surrey climb, plus the three men and three women who make the most attempts at the ascent.

With an average grade of 5 percent, Box Hill is 1.6 miles long and gains 411ft. The Olympic men's road race will climb it nine times, the women's twice.

To get on the Box Hill Challenge, get yourself over to Strava.
