The Belgian made the announcement on social media, explaining why he would be walking instead of running at a weekend charity event.
"Just literally out of the running. I am recovering from appendicitis, so unfortunately no Wings For Life World Run for me," Van Aert said. "Looking ahead to the preparations for the Tour and the Games."
The Wings For Life World Run raises money for research into spinal cord injuries, a charity Van Aert supports.
Van Aert didn't explain whether he needed surgery to treat his appendicitis or whether he expects it to disrupt his preparations ahead of key races still to come in his season.
Appendicitis can take as little as a few weeks to recover from, while if open surgery is needed to remove the appendix then strenuous physical activity may have to be avoided for up to a month and a half, according to public health bodies.
Even letterlijk uit de running. Ik ben herstellende van een blindedarmontsteking, dus helaas geen @wflworldrun voor mij. Blik vooruit op de voorbereidingen op de Tour en de Spelen. 💪🏼 pic.twitter.com/NcyXlHwsQHMay 8, 2021
If an ideal time to have appendicitis exists, this would probably be it for Wout van Aert. The Jumbo-Visma rider capped off a successful spring Classics campaign with victory at the Amstel Gold Race three weeks ago, having also won Gent-Wevelgem and making the podium at Milan - San Remo. The 26-year-old is not scheduled to race again until the Critérium du Dauphiné on May 30.
The French stage race will provide preparatory kilometres before the Tour de France, where Van Aert will once again be one of Primož Roglič's key domestiques in the battle for the yellow jersey, while the Belgian will likely also get his chance in the sprints.
After that, Van Aert will be targeting the Tokyo Olympic Games individual time trial event alongside Deceuninck - Quick-Step's Remco Evenepoel for Belgium.

Hi. I'm Cycling Weekly's Weekend Editor. I like writing offbeat features and eating too much bread when working out on the road at bike races.
Before joining Cycling Weekly I worked at The Tab and I've also written for Vice, Time Out, and worked freelance for The Telegraph (I know, but I needed the money at the time so let me live).
I also worked for ITV Cycling between 2011-2018 on their Tour de France and Vuelta a España coverage. Sometimes I'd be helping the producers make the programme and other times I'd be getting the lunches. Just in case you were wondering - Phil Liggett and Paul Sherwen had the same ham sandwich every day, it was great.

Ask a cycling coach: ‘Does maximal heart rate really matter in terms of riding performance?’
Is a higher or lower maximum heart rate better? Or is there even any point in comparing?
