seen no one saying much on this danny its a hard one m8 theres no set rule fast pigeons and distance pigeons are man made by breeding fast pigeons to fast pigeons and long distance to long distance birds but some strains or families can do both this is why some sprint famlies can win a long race sometimes and distance birds can win short races how you train and treat your birds is much to do with it so better to choose horses for courses depending on what you want to win or a family that are all rounders hope this helps a bit m8
