Swiss Olympian Swann Oberson shows a deep scratch wound she received at a FINA 10KM Marathon Swimming World Cup race.

“I didn’t feel it during the race, but afterwards, I felt something warm on my shoulder. A swimmer didn’t cut her nails and I had to see the doctor after the race.”

German Olympic medalist Thomas Lurz put in a good 1 hour and 53 minute swim in the FINA 10KM Marathon Swimming World Cup race in Cancun.

Under the bright, cloudless skies in the tropical paradise, but despite a heavy dose of sunscreen, he still got a bit of a sunburn.

But the Australians typically have the best sunscreen, applied frequently as Penny Palfrey shows before her latest channel swim in Hawaii.

She applies a layer before she leaves her hotel room, and then layer after layer of sunscreen as she prepares for her swims – the latest in the Caribbean Sea from Little Cayman Island to Grand Cayman Island between June 9th – 11th.
