Just days after Nairo Quintana had results showing a presence of tramadol during the Tour de France, another high profile rider has tested positive, this time on the mountain biking bubble where Mathias Flückiger is now under pressure.
Flückiger was the World Cup winner in the XCO discipline last year, aswell as being a three-time Swiss national champion, former under-23 World champion and winner of several other high-level races. A test taken at this year's national championships - where he took the title - came back positive for the substance Zeranol, an anabolic steroid that promotes body growth.

The news come as a surprise, and in the day the European championships will be taking place. Flückiger will miss the race, and likely the World championships next week aswell which will take place in Les Gets.
It is likely that he will now be requesting a B sample and preparing his defense, with big consequences set to be put in place if he is not able to prove his innocence.

- There was once a time when Lance was supremely popular and he used his artificial "It's Not About the Bike: My Journey Back to Life" persona to lead his mob in going after Greg. There was no one Lance did not abuse in protecting his phony hero image. Lance promoted himself as a divine megastar and he let down millions of cancer victims and gullible devotees who clung far too long to the charade. Lance is the epitome of a corrupt person and because of his power, many around him, including business enterprises, succumbed to the evil. All who got in Armstrong's way were mercilessly attacked by him and his minions. This remarkably continues today with a new generation. LeMond was a number one enemy and paid a huge price.

leedorney02-11-2026 - Watch the interview on youtube. I don't speak French. I do speak English and Spanish and you can hear it in his voice. Years ago LeMond had real personal problems I imagine in no small part because of Armstrong. then Armstrong goes round "full blast" re: LeMond having drinking and drug problems. The same way Andreu was expelled from mainstream cycling so was LeMond. On the positive side the clips of the ride and chatting with old teammates and was good. To seemed like a fun day and experience and good reason brush up his French.atom02-11-2026

Das ist ein ziemlicher Hammer, am Abend vor dem EM-Rennen und eine Woche vor der Bike-WM: Mathias Flückiger (33), der Olympiazweite und Gesamtweltcupsieger von 2021, wurde positiv auf die anabole Substanz Zeranol getestet.
