I know that, but the world of cheating could go beyond that. Involve money you are susceptible to cheating and nothing is impossible if the prize is worth the risk
Simple
Your loft is 50 miles nearer the race point, I raise birds in your loft and put my rings on them, I take them to the club and register them for the race, I take my clock to your loft which may have a seperate pad for my use,
Far fetched maybe but possible especially if it was a big money race etc
