Here's a deep compilation for 1st and 2nd day scores at Decathlon competitions, which would cover whole competitions even dnf or disclaimer results. I would as always welcome any additions not in the lists. Yoshiaki Oikawa
This handy combined events points calculator allows you to calculate both of men's and women's decathlon, heptathlon and pentathlon scores. Also adjust for junior competitions.
The Decathlon's nice in that you get to know the other athletes. It's almost like everyone helps each other out. We're all out there trying to win, but at the same time there's a friendship there too. It's always fun going to meets and catching up with the other guys - Tom Pappas
