Hi Steve M,
Nope, it's not my site and i'm not the one presenting. The guy presenting is Steve Levar who used to be a racing commentator in Singapore Turf Club. I've been trying to get more information on Singapore races and stumbled upon his video at his website
www.racingguide.com.sg so i thought i'll just share it with everyone here since it's very professionally done.
Well there's generally two surfaces in Singapore racing. Turf and the Polytrack. For turf races, it's further divided to long course and short course. The general rule of thumb is that their long course favors runners with strong finishing while the front runners have the advantage over the short course.
For the polytrack, i'm still studying this surface but i don't see any bias at the moment.
