After swimming across the English Channel, Catalina Channel, Molokai Channel and the Tsugaru Channel, Chembur resident Prabhat Koli, 19, on August 4 became the youngest swimmer to conquer the North Channel, which runs between Northern Ireland and Scotland.

Describing what he considers his toughest swim yet, Koli said: "The North Channel has been ticked off the list. This was surely the hardest swim I've ever done. The water was about 12°C - 15°C with loads of jellyfish that I somehow managed to dodge, but still received many stings. I felt really happy. While finishing the race, I was almost in tears."
