Sporza reports that two-time world cyclocross champion Bart Wellens (Telenet-Fidea) announced his retirement on Tuesday. He told Sporza that he made the decision after an underwhelming 2014-15 season that was hampered by back pain.
Wellens is also implicated in the ongoing investigation into Belgian doctor Chris Mertens, who is accused of providing ozone therapy to top athletes.
The 34-year-old Belgian won the rainbow jersey in 2003 at Monopoli, Italy and a year later in Pont-Château, France. He also won the cyclocross World Cup in 2003 and the Superprestige series in 2004.
