Hi guys, just been rewatching the UCI junior world champs from Aigle and noticed that in the first semi final sprint round between Hoffman and Cornish, Hoffman leaves the sprinters lane in turn 3 of the final lap. (See attached photo)

i was of the impression that leaving the sprinters lane,m after the sprint is initiated or in final 200m is a DQ. Have I got this wrong? Or does it need to be an “intentional” move rather than momentum taking you up track?
