Eli Ball is training to swim the English Channel... butterfly. Yes, you read that correctly. Butterfly. He is an exceptionally accomplished butterflying ocean swimmer, having completed a plethora of marathon ocean swims, including the 20km Rottnest Island swim, along the way setting the butterfly record.

Sharks are an ever present thought for ocean swimmers, and they are one of the topics in today's episode, which was recorded a few weeks before the incident. My sincerest condolences are with Simon's family and friends.
