the thing is you could probably send all your young birds untrained the drag would bring them back home if they stay with the main batch as most do i know of a few fanciers that actually do this , but not something I would do , 60 miles is short for a first race with ybs your not training for fitness there young and healthy . So yes by all means basket train them so the experience is not as stressful , but a few tosses up to 30 mile will put them in good order for there racing career ahead , once my birds go to there first race I rarely return them to a basket for training as Geo said there better off at home not running the bop gauntlet getting home and where you can train with as many fanciers at same time , I believe there's safety in numbers
