My Tips for some good betting is:
NumberSixValVerde - A good each way bet but with low odds it doesn't seem worth it!
Liberthine - Female horse, pregnant, amateur jockey who has won 3 from 5 runs round the fences at Aintree. Need I say more! Fantastic story - odds of around 25/1 (can get 33/1). My tip to win the Grand National!! (If there is any doubt it's over Stamina)
