They are pretty hard on a bike. Especially in the heat that he did it this year (I did some of them in the Alps the same week as the Tour this year. It was bloody hot!!)
I'm a big cycling fan. But like a lot of cycling fans, I just can't warm to Froome. Have a lot of respect for his achievements, especially the considering the stuff he put up with in the Tour this year, but he's just so boring. And he looks horrible on a bike. No style there at all. If Geraint Thomas won the Tour, he would win SPOTY by an absolute mile because he is much more likeable.
Bizarrely, I don't like Froome because he is boring despite me loving cycling, but I do like Andy Murray despite him being boring and me not really caring for tennis either. I don't quite understand that...
On Sinfield, I have a lot of respect for him. Think he has great leadership qualities, and love the way he keeps calm under pressure. Think the nomination was just reward for a brilliant career spent at the top end of his sport. And he's a good solid Oldham lad. Theres a lot to like there.
