David Millar says he wants to "enjoy sport again" after ending his career as a professional cyclist.
The Scot revealed cycling had become a "job" and a "burden" at times.
"I'd like to get back into sport being something I go out and have fun doing rather than worrying about numbers and science," he told BBC Radio 5 live.
Millar, 37, won stages in road cycling's three most prestigious stage races - the Tour de France, Vuelta a Espana and Giro d'Italia.
The former British road race champion served a two-year doping ban from 2004 for taking EPO, which resulted in him being stripped of the world time trial title he won in 2003.
Millar added that he wanted to stay in cycling, possibly in the commercial sector, but said: "I need a break from the whole racing scene.
"It's been my whole adult life, even my kid life since being a teenager."
