Kenyan marathon runner Wilson Kipsang has received a four-year ban for violating anti-doping rules. 

The 38 year-old has been suspended from the sport by the World Athletics’ disciplinary tribunal for ‘whereabouts failures and tampering by providing false evidence and witness testimony,’ the Athletics Integrity Unit has revealed. 

He is the former marathon world record holder and an Olympic 2012 bronze medalist. He has also won the London Marathon twice, the New York Marathon in 2014 and the Tokyo Marathon three years ago.

Kipsang failed to provide whereabouts information on four occasions and was accused of missing tests. 

All of his results since April 12 last year have been scrapped.

He has the right to appeal against the decision.
