After 49 days, endurance swimmer Lewis Pugh has completed his challenge to swim the full length of the English Channel – the first person to do so wearing just goggles and trunks. 

He's done it as part of a campaign to ensure 30 percent of our oceans are fully protected by 2030. 

Sky's Annie Green went behind the scenes to meet members of the crew to find out what life's been like at sea - and she caught up with Lewis as he finished his mammoth challenge. #TheLongSwim #SkyOceanRescue
