Great Britain collected their fourth medal of the championships in the men's 4x100m relay.
Britain's selectors had placed great hopes on the team adding to their medal tally in the relays.
And the quartet of Christian Malcolm, Craig Pickering, Marlon Devonish and Mark Lewis-Francis delivered with a bronze.
Laura Turner, Montell Douglas, Emily Freeman and Joice Maduaka were also unlucky to just miss out of the medals in the women's sprint relay.
Roman Sebrle fought back to take an elusive world title while Meseret Defar did likewise in the women's 5,000m.
Your thoughts on day eight, please.
