Great Britain and Northern Ireland’s mixed 4x400m team won bronze at the World Athletics Relays in Botswana, while four other GB teams also qualified automatically for the 2027 World Athletics Championships.
Alex Haydock-Wilson, Lina Nielsen, Jake Minshull and Yemi Mary John finished third in three minutes 8.24 seconds, behind the USA and Jamaica.
A place on the podium qualifies the 4×400 mixed team for the inaugural World Athletics Ultimate Championships in Budapest in September.
GB’s men’s 4x100m, the women’s 4x400m and the mixed 4x100m line-ups progressed to Sunday’s finals from Saturday’s heats, earning them a place in Beijing next year.
The women’s 4x100m team, who were disqualified after finishing second in their first day heat, came in second in their Sunday repechage to take one of four remaining World Championships slots.
However the men’s 4x400m quartet, who finished seventh in their first race, placed third in their repechage and will bid to qualify for Beijing on time at a later date.
The women’s 4x400m squad finished fourth, while the men’s and mixed 4x100m teams both failed to get the baton round in their finals.
British athletes won medals in all five relay events at the 2024 Paris Olympics, but failed to reach the podium at last year’s World Championships in Tokyo.
