Horsey's **** me if I understand betting, but if this is correct I'm bloody chuffed to bits. We all put £60 on horses at work.
I had a few on We all picked 3 horses. Aaaargh, I hate betting, it's too complicated for someone as simple as me.
So if you picked 3 horses 20 quid on each one I presume and you backed the winner at 66/1 then you will collect about £1300 if you backed the horse to win.
