Romain Mesnil, silver medalist at the 2007 Athletics World Championships in Osaka, used to be sponsored by US sports brand Nike but his contract expired last year and was not renewed.
"It was probably for budgetary and strategic reasons. It's the crisis," Mesnil said.
"In times of crisis you have to come up with a novel approac."
In the video, Mesnil is seen running naked, with his pole, as if preparing for a vault, through some of the capital's most famous streets including tourist spots such as Montmartre and the Pont des Arts across the River Seine.
Somewhat disappointingly, a black censor bar has been added to cover his private parts - this makes it hard to verify that he was, in fact, truly naked.
Mesnil added: "I was very concentrated on what I was doing. It was funny.
"There were tourists who were looking at me taking pictures, but I was really into it, a bit like when you're about to jump with a pole, you don't ask yourself any questions, you're really concentrated."
However, the footage has certainly whipped up interest with some 400,000 views by Wednesday morning.
