Sometimes punters see special runs from horses that nobody else notices.
You might be at the track with a friend who has just backed a 50/1 winner. You say to him "how did you back that" & they reply that it was a big run when finishing 8th etc.
Lets share this knowledge.
I have one.....Yogis Edition wait till it draws barrier 1,2 or 3. You get a good run.
