Well...I did my first race of the eyar...Charge Pond 3/21.
I don't know my exact placing, results aren't posted yet. But I wasn't dropped. I was in the front group the whole way, but the last lap things splintered and I was a few splinters behind the leaders...who knows ...maybe 20 or 30 seconds back.
What I do know;
22 mph avg speed
161 bpm avg hr...that is close to my 1 hour max effort
GPS, speed, and HR data: http://trail.motionbased.com/trail/activity/7848024
Check that HR graph ... incomplete recovery ...upward sloping troughs starting around lap 15. I am sure I couldn't have held the pace much longer.
Some video I made (my son was snapping pics, as well as doing the lap cards for the race official): http://www.youtube.com/watch?v=A8X2ApH_800
