Highlights, Day 2

Gabby Logan introduces highlights from the second day of the World Championships in Beijing, China.

Day two saw the finish of the women's heptathlon, with two Britons hoping for gold. Jessica Ennis-Hill has competed sparingly since her brilliant gold medal at the London Olympics having had her baby son Reggie. She and compatriot Katarina Johnson-Thompson completed the gruelling multi-discipline event with a punishing 800m.

The men's 100m took place with the legendary Usain Bolt looking to retain the gold medal he won in Moscow in 2013. He returns to the Bird's Nest stadium seven years after winning three golds there at the 2008 Olympics.

Eight-time World Championship gold medallist Michael Johnson joins Gabby to analyse the day's events.
