You’d think that Adam and Simon Yates would know each other pretty well — but we thought we’d put that to the test in a quiz designed to stoke up some sibling rivalry.

Does Adam know what Simon would rescue first in a fire? What’s Simon’s greatest achievement in cycling so far? And what’s the stupidest thing Adam has ever done in a race?

Both Orica-GreenEdge riders have had astonishing starts to their careers, and are now being talked of as future Grand Tour contenders. They were both selected for this year’s Tour de France — Simon’s second appearance in the race, and Adam’s first — and they made it to Paris after some excellent performances on the climbs.

Simon is a product of British Cycling’s Olympic Academy Programme, with impressive results on the track as well as the road. He won the Madison with Daniel McLay at the Junior World Championships in 2010, before winning the points race with the seniors in 2013. This year’s highlight was fifth place overall in the Criterium du Dauphiné, which also won him the young rider’s jersey.

Twin brother Adam developed via the Dave Rayner Fund, which allowed him to begin his career on the road in France with CC Etupes. Until this year his top result was the overall win at the 2014 Tour of Turkey, but this month he won his first WorldTour race at Clásica de San Sebástian.

All impressive stuff… but for some reason his brother thinks he should have worked in IT. Why? Watch the video above to find out.
