It's official now.. I managed to come under 5:00 hours - 4:59:27.
I am a bit relieved to know that I managed to scrape under 5:00 by a whisker. I wanted to do under 4:30 but managed to come under 5:00. I am still going to keep my goal of coming under 4:30 and hopefully will achieve that in 2008.
Please take look here.. gives quite a lot of interesting statistics.
