On paper, the dynamics of the World Championships heptathlon might look like what you would expect. The Olympic gold and silver medallists repeating their competition from Tokyo. A bronze medal on offer to a range of other athletes ready to step up.
If we dig a little deeper, it was not as straightforward as it seemed. It was a Benelux battle, and the young pair of Hall and Sułek did challenge for bronze. But the destinations of the medals were not decided until the last two and half minutes of the competition.
