Tom Dumoulin promised to make one last push for glory as he announced he will retire from cycling at the end of the season.
Jumbo-Visma rider Dumoulin won the Giro d'Italia in 2017 and followed up with success at the individual event of the World Time Trial Championships in the same year.
The Dutchman is also a four-time national time trial champion, while he has claimed three stages at the Tour de France, two at the Vuelta a Espana and four at the Giro.
Dumoulin, alongside his Giro success, finished second at the 2018 Tour de France and has two time trial Olympic silver medals to his name.
The 31-year-old featured at this season's Giro but has confirmed this campaign will be his last as he looks for a new challenge.
"I decided that 2022 will be my last year as a professional cyclist," Dumoulin wrote on Instagram.
"In 2020 I had a very difficult year and at the end of that year I got overtrained and burned out. At the end of 2020, beginning of 2021, I was only a shadow of myself and thus decided at the time to take [a] break away from cycling to think about my future.
"But despite how good it occasionally still was: many times, and especially this year, it has been a frustrating path, at which my body felt tired and still does feel tired. As soon as the load in training or races gets higher, I suffer fatigue, aches, and injuries instead of improving.
"The effort in training did often not lead to the desired performances. For a while now there has been a disbalance between my 100 per cent dedication, everything that I do and sacrifice for my sport, and what I subsequently get out of it in return.
"With a lot of patience and a very cautious approach, I'm convinced that I could get back to my full potential on the bike. But that would be a long and patient road, with no guarantees on success. I choose not to take that road, but to quit my active cycling instead and to take a new and unknown path.
"I especially look forward to the World Championships in Australia where I hope to get the best out of myself in the time trial one last time."
