I didn’t back out. I’ve done it. The Run4Fun.
My target time was 46m00s. My result:
I also tracked the route with the RunKeeper iPhone app. It shows pretty much what I felt during the race ie. that I ran at a consistent pace up until about the 8th kilometer, when I started feeling tired and slowed down significantly. Hence there is probably still room for improvement, by running at a pace that I can maintain for the full distance.
Actually I’m pretty tired now. Off for a lie down!
