Multi-time Olympic gold medallist, Jamaica’s Usain Bolt on Saturday, participated in his first-ever mixed-gender relay, leading the 'Bolt  All-Stars' team in the inaugural Nitro Athletics event in Melbourne. The 30-year-old sprinter raced in the mixed 4x100 metre relay, alongside fellow Jamaican sprinter Asafa Powell and Americans Jenna Prandini and Jeneba Tarmoh. "I've never handed over a baton to a girl. For me that was exciting," said Bolt.
