Paralympian Steve Bate was told he had the degenerative eye condition retinitis pigmentosa, which meant he could go blind in four years and would have to give up his beloved rock-climbing. Left with highly restricted tunnel vision for the time being, Steve responded by climbing the El Capitan sheer face in Yosemite National Park. A meeting with cyclist Karen Dark in 2012 inspired him to try competitive cycling. This year at the Rio Olympics he won gold in the 4,000m pursuit with pilot Adam Duggleby for Team GB and set a new world record
