Kenya's Hellen Obiri ran the fastest 5,000m in World Championships history to win gold in Doha.

The defending champion's time of 14:26.72 continued the trend in the championships of long distance runners breaking records to win. Fellow Kenyan Margaret Chelimo Kipkemboi finished 0.77 seconds back to take silver, while Germany's Konstanze Klosterhalfen finished third.

British pair Laura Weightman and Eilish McColgan ended with personal best times and finished seventh and 10th respectively. Eleven of the top 14 runners achieved personal bests in this fast race.

Obiri took the lead early on in the race and remained fully focussed as the pack of six athletes that were with her could not overhaul her.

Venezuela's Yulimar Rojas took gold in the triple jump with the fourth best distance in history. Her jump of 15.37m was an attempt that no one else could get close to.

She jumped another 15+ metre distance in her fourth attempt, which would also have been enough for gold. Jamaica's Shanieka Ricketts won the silver medal with a jump of 14.92m and Colombian Caterine Ibarguen took bronze.

Elsewhere, GB qualified for the 4x400m relay final with a season best time of 3:24.99, but USA and Jamaica will be favourites to win gold tomorrow.

Both Jamaica and USA looked very strong in the heats, with Jamaica posting a world leading time of 3:23.64 in heat one. But then USA took the world lead back with a time of 3:22.96.

Olympic champion Brianna McNeal was left distraught after a false start saw her disqualified in the 100m hurdles heats.

Having missed the world championships two years ago due to a ban for missing three drugs tests, this was yet another setback as she looks to regain confidence and form.

Team GB's Cindy Ofili, who finished just outside the medal places in Rio 2016, qualified for tomorrow's semi-final with a third place finish in heat one.

Shara Procter and Abigail Irozuru will be representing British hopes at tomorrow's long jump final after qualifying. Both qualified for the final on their last jump.

But there was disappointment for Jazmin Sawyers as her jump of 6.45m was not enough to make the cut-off for the final.
