Gabby Logan presents live coverage on day eight as the opening events of the decathlon dominate the morning session. The retirement of all-conquering American Ashton Eaton has handed a golden opportunity to the likes of Canada's Damian Warner and Kevin Mayer of France. They get underway in the 100m, followed by the long jump and shot put.

Two former global medallists are in action for Great Britain, with Tiffany Porter competing in the opening round of the women's 100m hurdles and Robbie Grabarz aiming to qualify for the men's high jump final.
