Sir Mo Farah is on the brink of track retirement after successfully defending his 10,000m and taking 5000m silver at the World Championships.

He will focus on the marathon after running at the Birmingham Diamond League next weekend and a last race at the Diamond League final in Zurich on August 24.

Here, Press Association Sport looks at the athletes to give British Athletics hope over who can fill his shoes.

The 21-year-old from Watford, who grew up peeling potatoes at his mum and dad’s fish and chip shop, almost claimed a shock bronze in the 800m.

He was 50-1 to just reach the final at the start of the championships but a stunning final 150m saw him just miss out as he finished fourth.

Langford has the personality and humility to be relate to athletics fans and has already said he wants to inspire the next generation to get into the sport.

There is a wall of fame at his parents’ shop and if he builds on his summer there will be a few more pictures of Langford adorning it.

Laura Muir

She was already on the road to success before the summer having earned two gold medals at the European Indoor Championships in Belgrade in March.

The Scot may not have won a medal but there is clear hope she will be an Olympic and world contender for years to come, stepping into Farah’s long-distance shoes.

Muir is unassuming and comes across as almost shy but she has proven she has got the right stuff on the track with her gutsy performances.

The shot of her collapsed on the track after the 5000m heats is one of the few enduring GB pictures of the championships.

Nethaneel Mitchell-Blake

The 23-year-old does not have much to say off the track but he made a statement in the 200m by finishing fourth and then anchoring GB to 4x100m relay gold.

There is real pace and prowess from Mitchell-Blake when he gets onto the track.

His victory in the World Championships trials last month was the first time he had run in Britain since he was 13 years old having been educated in America.

He made the Olympic semi-final last year and there will surely be better things to come.

Dina Asher-Smith

The 21-year-old was so close to a medal despite having broken her foot in February just before the Birmingham Indoor Grand Prix.

She finished fourth after running 22.22 in the 200 metres – a time which even surprised her – to be pipped to a bronze medal by Marie-Josee Ta Lou.

‘Dasher’ was also part of the women’s 4x100m relay squad who grabbed silver on the penultimate evening of the World Championships.

Her performance following an injury-hit winter and build-up shows great promise ahead of next year’s World Indoors and European Championships.

Reece Prescod

The 21-year-old was the only British man to make the 100m final which ended so dramatically with Justin Gatlin’s win.

He finished seventh in 10.17 seconds – having set a personal best of 10.04secs the day before – in his first ever world final.

Without Usain Bolt chances will now open up – despite the emergence of Christian Coleman – giving Prescod a shot.

He also took a shock victory at the British trials in July to secure his place on the World Championship team.
