It's hard not to question the elite in the £1billion London Marathon

As the single biggest annual fundraising event on the planet burst through the billion pound mark, there was so much to admire about Sunday's London Marathon. Eliud Kipchoge is setting records while his country is in the midst of a major doping crisis By the time they finished, two had crossed the line faster than the record Eliud Kipchoge obliterated with his 2.01.39 in Berlin last September, and London now boasts the fastest second and third placed runners in history. Among those who have been exposed is Jemima Sumgong, the winner of the women's Olympic marathon in Rio, Asbel Kiprop, an Olympic 1500m champion, and Abraham Kiptum, the world record holder for the half-marathon who was withdrawn from this race on Friday after the IAAF provisionally suspended him for an athlete biological passport violation. Callum Hawkins came within seconds of the world record Steve Jones ran and finished 10th Kiptum came to London as one of the favourites but succeeded only in adding to the credibility issue that — in fairness to the Marathon Majors — they are trying to combat with the funding of extra drug tests for the finest athletes over 26 miles. Yet can we really believe everything we are seeing when Callum Hawkins comes within seconds of the world record Steve Jones ran in 1984 and finishes 10th, more than a mile and almost six minutes behind the winner?
