THE Chinese walk results below unusually had four races in four days and therefore gave slightly different results than had it been a single competition.
Are athletes now less capable of doing more than one event than in the past?
Certainly, in London 2017, athletes struggled to double successfully. The 100/200m and 5000/10,000m double has been achieved regularly in recent championships through Usain Bolt, Mo Farah, Tirunesh Dibaba etc, but this time there were no double champions.
Wayde van Niekerk won medals at 200m and 400m and Farah added a 5000m silver to 10,000m gold but unusually double golds were absent.
One pair of events that regularly used to see doubles was the 800/1500m. It was of course successfully achieved by the likes of Peter Snell, Kelly Holmes, Seb Coe and Steve Ovett.
Caster Semenya did gain two medals in London, but men certainly now seem to consider themselves either 800m or 1500m specialists and doubles are rare in the events in championships. Though most 1500m runners run 800m more than the two-lap men go longer in smaller meets.
