Looking at the splits, what the hell did you do to number ten to smash the field by so much? Is this one you actually middled for a change - or just fit and strong? (note, for some strange reason I was good on 9 - I didn't speed up consciously or do anything different there).
He probably ran up the hill, like the nutter he is.
I got a stick through my ankle right before #9 so I didn't have a lot of hope, but my 2:00 doesn't look so bad, considering :-)
