He's been quite specific about his sensations, and while he could "also" have covid, it doesn't sound like that is the reason why he has been underperforming.
That honestly sounds like reaching. Johannessen (barely) won Avenir the day before turning 22 as a 4th year U23. He is older than Evenepoel, in case people forgot. While i think he has more climbing potential than Foss, i haven't seen anything to suggest he will be better than Uijtdebroeks (who was a 1st year U23 when he won Avenir). At least as a GT GC rider.
Comparing him to Foss and Blackmore makes sense, given their age when they won Avenir.
On the surface, THJ might not seem like an extraordinary rider—unless you're familiar with his career so far. But here's what I know about his situation:
1. THJ had only been racing for three years before winning L'Avenir, and during that time, he was mostly just mountain biking on weekends with minimal training, according to the data.
2. Over the last three years, he faced significant challenges: a severe knee injury kept him out during two winters, and in the third year, he was sidelined by COVID and other illnesses.
3. This year, he showed incredible form, dominating riders like Lenny Martinez, Woods, and Gaudu at a race in "Var" (I can’t recall the exact name). Unfortunately, a tactical mistake cost him in the final, and then he injured himself, missing the rest of the season until the Ardennes, where he was decent. However, he suffered another knee injury before the Tour and didn’t ride at all during Uno-X's altitude camp. Despite this, after just three weeks of training, he was competitive in Slovenia and performed strongly in the Tour.
4. His brother, also a huge talent, hasn’t been performing due to heart surgery after 2021.
5. During this year’s Tour, THJ was as good as, if not better than, riders like Hindley, Mas, and De Plus on stage 15. He might have even been better than Carapaz, but Simon Yates created a gap before the penultimate climb. THJ closed a one-minute gap to grand tour winners and matched their strength on Plateau de Beille. It was incredible.
6. You could see similar performances last year, particularly on stage 17 up Col de la Loze, and again on stage 20. Despite spending so much energy trying to get into the breakaway, he still managed to keep pace with the GC contenders, finishing 9th in the GC group.
7. He has an insane sprint for GC guy- Pogacar level.
8. He can't time trial. Only drawback so far.
He is a mix of Alaphilippe and Adam yates. Magical beast.
