World Relay Championships: GB women's 4x100m miss out in heats
Great Britain's women's 4x100m relay team missed out on the chance to qualify for the World Championships as they failed to finish their heat at the World Relays in Japan.
The reigning world silver medallists did not finish the race after a baton mix-up between Desiree Henry and Ashleigh Nelson in Yokohama.
