I'm fairly new, but my method was to start road training after the birds have been loft flying for 45 min. or more twice a day. I use sun up and 2 hrs prior to sunset for my loft flying. I like to loft fly them in the morning, call them in with a few grains of feed, then basket them for a toss of 5 mi. if they come home with no problems I take them 10 mi. the next day, 20 mi. two or three times, 30 mi. same, at this point no loft flying first. 50 mi. 3 times, and 70 mi. a couple of times. I generally toss in groups of 7-10 birds with a couple single tosses. I started with 25 youngsters and lost none prior to the first race.
