I may have heard it wrong, but didn't he say something about pulling his kids around on his 4 wheel trailer in the snow?
Thing is, with the best will in the world, riding your bike around for 200 miles a day, day after day, come what may, could easily wear a bit thin and start to feel a bit meaningless if you love your kids, begin to miss them and fancy spending time with them. He also does a lot for work for a local charity to help orphaned children.
As they say over there - go figure.
