The 27-year-old shot into the national spotlight last summer when she secured double lightweight sculls gold at London 2012 alongside Kat Copeland.
But while Copeland has since reiterated her desire to carry on and compete at the next Games in Rio in 2016, Hosking had kept quiet on her future.
And she insists it is unlikely we will see her in a boat again as she pursue a law degree.
“I have taken some time out from rowing and have been doing some charity cycling events,” said Hosking, who graduated in 2007 from Durham University with a chemistry and physics degree.
“The team have already competed in a World Cup at Sydney and I sort of watched that because I still have a lot of friends in the team and it was great to see them go out and compete again.
“I am going to finalise my final decision [in regards to the future] in the next few months but I am erring on the side of retirement.
“I have got a place to start studying law in September so I am going to do that. It is going to be a nice challenge and I am really excited about the opportunities that will bring.”
The National Lottery Anniversary Run will take place on Sunday July 21. Places are available via
