Jessica Hull is confident she's a better runner now than the athlete who won Olympic 1500m silver in spectacular style in Paris last year.
As is the case pretty much every time she toes the starting line, four-time 1500m world champ Faith Kipyegon is the prohibitive favourite for Tuesday night's 1500m final at the world championships in Tokyo.
But if you were to make a case for anyone to cause a huge upset, it would most likely be Hull.
