The 25-year-old was one of few swimmers to impress at the London 2012 Olympics last summer as he finished fifth in the 10km open water event in Hyde Park's Serpentine.
But ultimately he didn't contribute to Britain's medal tally which fell short of the target of five to seven with just three secured, Michael Jamieson's silver and Rebecca Adlington’s double bronze.
That led to a review into the London 2012 performance with one of the recommendations coming from it suggesting that Britain's open water swimmers need to race more.
With that in mind a six-strong British team, headed up by British 1500m champion Fogg, has been sent to South America for the opening two legs of the FINA Open World Cup Series.
Tom Allen, Tom Sunter, Jack Burnell, Lucy Charles and Rachel Williamson complete the squad that will compete in Santos, Brazil on Sunday and then Viedma, Argentina six days later.
And Berni Dietzig, interim head of open water for British Swimming, believes racing twice in the space of a week will be a true test of Fogg's potential in particular.
"Findings in the performance debrief following the London Olympics recommended that our open water swimmers need to race more and get more experience of racing in a range of conditions," he said.
"This is the first opportunity in 2013 to take on some top competitors and these two races are usually well attended so they will be competitive.
"The two races will have different conditions; one is in the sea and the other in a river so the team will experience all kinds of currents, swells and flows.
"Usually they will have a week to ten days recovery time after a 10km race and they won't get that this time so it will be a big challenge for them."
