Ok, these are all from when I was a good 10 years younger, and a lot fitter....
3 mile run - 19.50
20 metre shuttle - level 7 (ahem, i was rubbish at it!!)
100 burpies - we never did the press up side of it, so wouldn't count
2k on rower - 7.19 (I was the worst in my year by a good way

)
Press ups in 1 minute - 60+
If I were to do it today, I'd guess...
3 mile run - 22+
20 metre shuttle - level 4
100 burpies - dunno
2k on rower - 8.50 followed by mucho
Press ups in 1 minute - 35+
Will do the burpies and press ups one evening and find out though.
Nice idea for a league table
