Arthur van Dongen worked with Tom Dumoulin for many years Rabobank Development and Sunweb and after Dumoulin announced his retirement earlier this year after mental and physical fatigue, van Dongen believes he knows why.
In van Dongen's opinion "Grand Tours may have been too demanding" for Dumoulin. His explanation for this opinion is "His heart was probably more in time trial and riding classics and short stage races. He wanted to ride the Amstel Gold Race, the Walloon Arrow and Liège-Bastogne-Liège, but that did not always fit into his program. If you want to excel in a Grand Tour, you have to live like a monk for a large part of the year."

Despite Dumoulin not being able to live up to the lofty expectations many had for him when he joined Jumbo-Visma, the 54-year-old sports director doesn't believe it was a complete failure. As van Dongen says "
In the 2020 Tour de France, where Primoz Roglic wore yellow for a long time and he himself eventually finished seventh in the standings, he was certainly important. And in the Vuelta won by Primoz that year, his contribution was very distinguished. I don't think Roglic would have become the overall winner without that contribution."
The mental struggles of being expected to perform at the highest level throughout the 3-week Grand Tours eventually proved too much for Dumoulin as he called time on his career earlier this year. van Dongen sums it up well when he says
“The common thread through his years at Jumbo-Visma was Tom's struggle when it came to his intrinsic motivation to be the leader in a grand tour and/or a well-known Dutchman."

- great analysis thanks! appreciate you posting this. I didn't realize CX had a different standard for deviation. this is even more egregious it seems.mij10-11-2026
- As he isn't currently with Red Bull, I guess if he want to race for one more year he needs to find a team. He's 37 so this will be his last year I would guess, unless he wants to race for almost nothing like Froome did.awp10-11-2026
- I think some are making much ado about nothing. Even though Jonas is getting older, before his crash in the Tour, he looked like a solid 2nd all the way home. No one can really climb with Tadej until this year, Eric Mas showed himself which I think was a one off year for him and Paul Seixas has been able to be pretty close to him. Whatever stage race Jonas enters as long as Tadej is not there he is a favorite to win.awp10-11-2026
- Giro or not Giro, he won't win the Tour!MajorPayne10-11-2026
- Very true.awp10-11-2026
- Ciccone had a very strong end of season. Consistently attacking and livening up races. Hope he makes that last leap in progress and starts notching some significant wins. Great rider to watch.Occam10-11-2026
- Me too!!!!!Occam10-11-2026
- they can sign any 100 of top riders today but Pogi will win over Remco any time at the TDF unless something goes wrongabstractengineer10-11-2026
- the time for a GC rider to retire is when they cannot win stages, or have a significant level drop like from winner/podium into top 5/10 consistently. Roglic is still competitive and Froome raced even though he became pack fodder.abstractengineer10-11-2026
- He should be in a different team. It was detrimental. For them it does not matter if he does not develop. He should have gone to a team where they need him to succeed.abstractengineer10-11-2026
