The saga on Toon Aerts's Letrozole case is set to end very soon. If not this week then the next, a decision is set to come from the UCI throughout the Christmas period regarding the Belgian rider.
Aerts, one of the most prominent cyclocross racers of the past years, has tested positive for the substance letrozole, which blocks the formation of estrogen, hence helping with the production of testosterone in the body.
