This week on Catch Our Drift we are focussing on the ocean and sport. Oliver and Helen are interviewing some of the world’s greats about their relationship with the ocean. Formula One champion Nico Rosberg tells us about his new sustainable racing venture, Extreme E, and his own drive to improve the planet. We talk to Miranda Merron from the middle of the Atlantic as she races in the solo round the world yacht race, the Vendée Globe and World Freediving Champion Alenka Artnik tells us about how it feels to be diving alone on just a single breath of air at tremendous depth.
