I am training mine at the moment from 12 miles.They ve been there about 6-8 times now so they will be ready for next year.If they dont train, they go out around the loft.Sparrowhawks chasing them for a couple of hours lets them know what to expect in the coming years and they get wise to it.Some of mine havent thrown a flight , they were that late but they train just the same.They will be expected to compete to 280 miles at least this year coming, no probs.I timed a latebred from Ypres 456 miles in its 5th race of its life so they have either got it or they havent imo.Another 2 yr old latebred timed from 532 miles in its 5th ever race.The bottom line is, I think they need trained in year of birth, no matter if late or not.
