"As a young boy I dreamed of racing my bike professionally. With the support and guidance of many, I was able to pursue those dreams,” Hunt said on his team's website.
Hunt began his professional career in 1996 when he signed for Miguel Indurain’s Banesto team and has since featured for BigMat - Auber '93, MBK-Oktos-Saint Quentin, Mr Bookmaker, Unibet.com, Credit Agricole and the Cervelo TestTeam.
"Through the difficult times and memorable moments, the experiences during my career have been far more fulfilling and memorable than I would have ever imagined," he added. "Those moments will stay with me forever, have matured me and have given me a lifetime of experiences. I know cycling will always remain a part of my life, whether I am a professional or city commuter, as it is my passion. "After reflecting on my career and considering my future and family, I have made the decision that this will be my last season of racing."
Meanwhile, Cofidis rider Jean-Eudes Demaret has also confirmed his retirement from racing .
"GP Fourmies, last race of my career. My head is ready to move on to something else, even if I still have one year left with Cofidis," the Frenchman tweeted.
He is the second Cofidis rider to sign off at the weekend after team-mate David Moncoutié raced the last stage of his career at the Vuelta a Espana.
Demaret, 28, has suffered from Crohn's disease, a chronic inflammation of the bowel.
