Callum Hedge continues to lead the New Zealand Formula 1600 Championship heading to its penultimate weekend at Taupo Motorsport Park this weekend (February 2-4). The 14-year-old hasn’t had it easy with fellow Aucklander Josh Bethune showing on track that he is his closest rival when the two traded first and second places at the last round at Teretonga Park, Invercargill, in their respective Mygales.
