We have created a quiz that is dedicated to grey horses looking back through some of the best fillies, mares, colts, geldings and horses that have ever graced the sport ahead of the quirky Grey Horse Handicap at Newmarket this weekend.
There has always been the underlying thought that grey horses aren't as good as other horses but this is in fact a lie, with the colour of the horse having nothing to do with there pedigree's or how they are trained.
Over the years of the sport on both the flat and over jumps there has been some amazing grey horses that have gone on to win some of the biggest races in Britain and Ireland.
In this 12 question quiz we have given you the race the horse has won and the trainer he or she was or is still trained by to make it easier for you.
You have only two and a half minutes to complete this quiz and even with the clues you will have to have a real think with some older horses added in.
Good luck!
