Oliver Naesen, who was seemingly on a decline, resurged at the
Tour of Flanders this spring, taking a step up along with the whole Decathlon AG2R La Mondiale formation. But in the end it turned out that something else was behind Naesen's struggle.
...
The cause had to be found somewhere else, in something very innocent: celery. "My blood has been drawn countless times, but nothing has ever been found. The breakthrough came when I reacted very strongly to celeriac one day. My throat closed. Dorien happened to not be at home. I thought I was going to have to call an ambulance."
Problem solved, although that is certainly easier said than done. "Celery is in f*cking everything. On Sunday after Roubaix we ate fries. I looked it up: the only 'meat' I could order in the chip shop was a Bicky Burger, everything else contains celery. So that's what I learned this week."
