Mo Farah's stablemate Galen Rupp put aside 2015 doping allegations to record an impressive marathon debut time of 2:11:12 at the US Olympic Marathon Trials in Los Angeles last weekend. Rupp broke the tape ahead of veteran marathoner Meb Keflezighi (2:12:20) to secure a place on the Olympic team for Rio in August.
Rupp, who was at the centre of doping claims around Alberto Salazar last summer, might now target both the marathon and 10,000m at the Olympic Games. Optimism is high in the Rupp camp after a confident debut at 26.2 miles against a high quality field and in hot conditions.
The Olympic marathon is eight days after the 10,000m in Brazil so it's possible for Rupp to consider a double bid. Salazar himself believes that Rupp is: 'a 2:05 guy some day'. The drugs controversy, Galen Rupp's relationship with Farah and the tantalising prospect of a serious American contender all mean that this year's Olympic marathon is developing into a dramatic encounter.
At this stage it seems unlikely that Galen Rupp can even threaten a podium position in the Olympic marathon but his pedigree (and turn of foot) at shorter distances means that he might be a surprise contender in what is typically a slowly run race.
