the one thing you need is a lot of luck as there is so many things that can go wrong or right i got a good racer home a few year back and he was busted in 2 half's by a falcon i really dont know how he got home tbh even 6 hrs after i tought he was going to die a week after i put him in the stock loft he went he is sire grand sire and great grandsire of winners not only for us but other people too his children etc win from 60 mile and from the channel i reckon another 4 or 5 mile he would not of got home that i consider luck no great thinking or i knew he was going to be a excellent breeder have to say though he was a machine while racing
