No less than six of the top nine in the London 1500, including the gold and silver medallists, have served bans before or since. Briton Lisa Dobriskey finished 10th in the final and famously said afterwards: "I'll probably get into trouble for saying this but I don't believe I'm competing on a level playing field." American Shannon Rowbury finished sixth in London and went through the same emotional mix of anger and frustration as Dobriskey. Rowbury will at least get another chance to make up for her disappointment in Rio, having qualified for her third Olympics. Fifth-placed Ethiopia-born Swede and 2013 world champion Abeba Aregawi tested positive for meldonium in January this year, although had her ban was lifted in July due to a lack of clarity over the drug's properties.
