How hard do you have to train to do all 12 disciplines in one sitting! Did you watch the first one at the Olympics in London?
Training can be up to 5h a day but I don't do all events each time. The 1st olympics I remember is '88
So do you have any other inspirations other than Daley? Didn't Bruce Jenner win gold in 1976 for the Decathlon? 
roman sebrle is a legend, 1st man to score over 9000points and has 49 decathlons over 8000 points
He is a legend, such a shame how London 2012 ended for him. But his legacy will go on. 
shame he didn't get to 50 over 8000, unlikely that anyone will break that record
So close, I will be intrigued to see if any one can knock Kevin Mayer of his pedestal but we shall see.
think he has got a few more years at the top and could extend his WR further
That would be amazing, Do you have any dreams of competing to that level ?
that would be the dream, but I'm too old now and no where near good enough
