Rules:
In any race, bet a horse if it is the only previous winner over today's distance, provided that it is also one of the first three named in the Racing Post betting forecast.

System applies to UK races only.

Staking:
5pts to win on each selection.

Logic:
Horses are very susceptible to changes in distance. They may not perform at their best with even a slight increase or decrease in the distance they have to run. If there is only one horse that has previously won over today's distance it may well hold a big advantage over the others.

More than half of all winners are in the first three named in the Racing Post betting forecast, so this qualifying factor eliminates no-hopers whose distance win may have been a long time ago, or in a very low grade.

Results based on 5pt wins (100 bets):
