I watched Jade Jones: Fighting for Gold on the BBC iPlayer last night. I have been a rabid Welsh fan of hers since she won her first Olympic title in 2012. My transition from someone who had never seen taekwondo before to a conspiracy theorist who thought, before she prevailed, that the judges weren't giving her a fair crack of the whip as I watched it on the telly was a miracle to behold.
I am writing this later than usual as I have been on the road all day. A by-product though is that I heard Jessica Ennis-Hill on Desert Island Discs.
I was very struck that for both if these extraordinary athletes, their maternal grandfather was a high influence and driving force.
