NFS - The thing about Tough Guy is that although it is dressed up in a 'race' it is basically a very personal challenge and everyone has different demons to overcome. If you completed every obstacle then you hopefully felt very proud on picking up your medal. Apart from the first fifty or so when the marshalls are being more vigilant, the emphasis shifts to safety and participants are encouraged to do as much as they can but noone is forced to do anything they don't want to.
My mates and I watched as several people walked round all of the water obstacles and commented that they may as well have stayed at home and run a couple of laps of Richmond Park. To my mind, if you haven't got your hair wet (and your head frozen) then it isn't very tough.
I guess what I am trying to say is that time and position are meaningless at Tough Guy, unless you are in the top ten or so, it's how you feel inside about the achievement that is important.
