Sep Vanmarcke retires from pro cycling with cardiac issues - "It is very sad and painful to announce the end of my career in this way"
Cycling
Sep Vanmarcke was one of the most prominent and popular classics riders of the past decade, but he will now be ending his career with immediate effect as recent tests reveal scar tissue in his heart which could lead to further complications.
"Following an abnormally high heart rate detected while on the bike, Vanmarcke underwent testing including a cardiac MRI which confirmed the presence of scar tissue," the team has revealed in a press release this morning. The high risk of further cardiac complications posed by the scar tissue means that Vanmarcke will no longer be able to continue racing as a professional cyclist."

The sudden update comes as a shock. After undergoing exams recently the conclusion has been that the Belgian should not continue cycling at the highest level, in order to prevent possible complications such as what was the case with Sonny Colbrelli last year. Hence Vanmarcke hangs up the wheels today, after 16 years in the peloton.
“When I pinned a number for the first time back in 2003, I never dared to dream about having a professional career. I ended up living that dream for 14 years, with highs and lows. I wasn’t the super talent, but with dedication and hard work I was able to compete with the best riders in the biggest races for years," Vanmarcke said. "I got to know many people and cultures all over the world and have been to places I never heard of before.

“I would have liked to have raced at the highest level for a few more years and achieve more great performances together with IPT in the biggest races. It is very sad and painful to announce the end of my career in this way. At the same time, I am grateful that the problems with my heart were discovered in time. I’m going to take the time now to be with my family, to accept the situation and think about what I want to do in the future. My whole life has been all about cycling. Cycling will always be my passion.”
Vanmarcke became a professional rider in 2008 with the Davitamon Lotto Jong Vlaanderen team, and has over the years bounced back and forth between Pro Continental and World Tour level. Over the year's he's represented Garmin - Cérvelo (and later on rejoin the team which is now known as EF Education), Belkin (now known as Jumbo-Visma) and since 2021, Israel - Premier Tech where he has raced for the final time.

Vanmarcke was throughout many years one of the best classics riders in the peloton, however always with bad luck chasing him notoriously. Crashes and mechanicals often times came in the way of his results, however nonetheless he was still able to achieve success in the cobbles, rivaling the likes of Fabian Cancellara and Peter Sagan at his best.
He has won Omloop het Nieuwsblad in 2012 which ended up being the biggest win of his career. However he's had multiple podiums accumulated in races such as Paris-Roubaix, Tour des Flanders, Gent-Wevelgem, Kuurne - Bruxelles - Kuurne and Dwars door Vlaanderen. He's also won the Bretagne Classic in 2019, and his most recent triumph was at the 2022 Maryland Cycling Classic. Vanmarcke rode his final cobbled classics campaign this spring, finishing on the podium of Gent-Wevelgem proving his current form, and his last race was at the Belgian national championships.

- Eccelente! That's 7 riders in total in Red Bull who come from the devo team, 8 if you include Lipo
Rafionain-Glas09-11-2026 - again, nothing is going to be resolved. it is a discussion board. I simply said I didn't see how MS impeded LBs sprint. the UCI doesn't care about my thoughts, and I am really not that emotionally invested in it.mij09-11-2026
- provoke change, lol. this is a discussion board. nothing is going to change by what I say here. just commenting that it didn't look like MS impeded Brand. beyond that not trying to go too deep.mij09-11-2026

- so what i understand is: i left a comment calling out the endless author CVs for being an unnecessary flex of expertise, and you responded by lecturing me (and others) on discrimination and value systems. hats off to you. you definitely lost me!Ketterechts09-11-2026
- I just love the flood of Americans into the top ranks of world cycling. In addition to being studs on the bike, they all seem to be excellent emissaries for our country.Occam09-11-2026
- ANATOMY OF A G.O.A.T. EDDY MERCKX about TADEJ POGAČAR: Merckx: “He has revived a style of cycling that we had almost forgotten. He is now better than me.” Key statements by Merckx about Pogačar in 2026: - Acknowledging his superiority: This time, Merckx openly admitted, without any subsequent backtracking or reservations, that Pogačar had surpassed him and was now above him. This contrasts with 2024, when he quickly softened his remarks about Pogačar being faster. - The possibility of a historic triple (Giro, Tour and Vuelta): During the July Tour de France (where Pogi claimed his fifth title), Merckx stated that Pogi was the only cyclist in history capable of winning all three Grand Tours (the Giro d'Italia, Tour de France and Vuelta a España) in a single season, provided the conditions were right and he had sufficient team support. - Lack of serious competition: Merckx emphasised that Pogačar has no real rivals in the mountains since 2024, thanks to his extraordinary climbing ability and the fact that he continues to improve despite still being under 28 (he turned 28 in autumn 2026). - Praise for his racing style: Merckx highlighted how Pogačar is bringing back the aggressive, uncompromising spirit of cycling's golden era, when races were not merely about calculated stages and tactical conservatism, but about attacking from long distances. PS: This is not "boring" ... this is called making real history, not only statistical history. Capish?PogiSloFans09-11-2026
- It’s off-season mate, I’m bored and fed up with the mediocrity of people unwilling to provoke change when they admit things aren’t right. What have you done lately to make anyone realise you won’t put up with things? What conversation, are you dictating to me which part of the incident I have to be interested in or telling me other parts are taboo? That’s what I guess the UCI would really like, let them moan, let it blow over for them pass on to the next thing, let’s keep the status quo, let’s try our best not reviewing or revealing anything about decision-making just like every time before, they’re used to it by now so we can take the risk they’ll never give us grief.Jumpyjohn09-11-2026
- As far as CUTD headlines go this is far from the worst. It helps if you look at it twice and realise it’s a list of descriptions from distinct events. You can’t deny the reality of being a rival if you consider the picture immediately below, frontrunner is unfortunate but I’m guessing this time it’s more a linguistic failure than a clickbaiting opportunity. Just a reminder that this is not an anglo website, for those who find it too tedious to interpret text to get the gist of things which are rarely of great importance (as opposed to eg purposely biaised DOJ extradition translations in order to achieve hidden agendas), there are plenty of anglo cycling websites google can suggest.Jumpyjohn09-11-2026
- Ah, finally someone willing to be a bit proactive.Jumpyjohn09-11-2026
