Britain’s 4x100m men’s team failed to qualify on Sunday after finishing ninth in the heats, although they will have other opportunities.
Each country whose relay team reached and completed an A final was awarded an Olympic berth in that same discipline in Brazil.
The GB 4x100m women secured their bronze ahead of Canada by 0.01 seconds after Adeoye dipped over the line for a time of 42.84 seconds, with Jamaica (42.14) and the United States the top two teams.
Britain’s 4x400m women looked more comfortable in winning their bronze medals as they crossed the line 0.3 seconds faster than France in a time of 3 minutes 26.38 seconds, while the USA took gold ahead of Jamaica.
“Qualification really takes such a weight off our shoulders and now we can really focus on building this team for Rio next year,” said 4x400m team member Eilidh Child, who ran with Anyika Onuora, Kelly Massey and Seren Bundy-Davies.
Britain’s 4x400m men’s team, comprising Conrad Williams, Rabah Yousif, Jack Green and George Caddick, finished in a time of 3:01.50 as USA won in 2:58.43, ahead of the Bahamas and Belgium in third.
Meanwhile, Bolt’s absence appeared to deny us a chance to see the World and Olympic champion go head-to-head with in-form Justin Gatlin on the anchor leg.
But in any case, Gatlin’s USA were disqualified after a botched changeover going into the third leg as the Jamaicans eased to victory.
It is understood that Bolt did not run as a precaution after he reportedly felt tightness in his hamstring when warming up.
