My guest this week is Gus Barton (@ocean_ready_) - an ocean rowing fitness specialist and bona fide endurance athlete in his own right!  Gus has coached ocean rowers to go on and break 8 world records and complete 23 ocean crossings AND was himself part of a 4 man crew to break the transatlantic rowing record in 2015/16.  Gus is a great guy and shares some fascinating insights into what these challenges are like and the importance of mental resilience in long, multi-day endurance challenges, particularly when weather and other variables take control out of your hands!
