When did the birds last fly the 350mls that went previously? What are your plans for there next race? When i have birds in distance mind, there first race is 100 miles, then 200, then about 380, then either into 500 or 600 miles. the ones that done 150 mls if fit and healthy should easily do the 350mls, especially because you have the old english distance blood, id want to be pushing my birds to the distances There made for! But then again all across the country latly has been funny racing!
