• Four-year ban upheld by court of arbitration for sport
• Salazar helped coach Mo Farah to Olympic golds

The US distance coach Alberto Salazar, who guided Mo Farah to four Olympic gold medals and six world titles, is understood to have lost his appeal against a series of doping violations.

Salazar had vowed to clear his name after being sanctioned in October 2019 and appealed to the court of arbitration for sport. However after a virtual hearing that lasted seven days in March, his sanction was upheld and as a result he will have to serve out his full four-year ban. Cas’s detailed explanation for its decision is expected shortly.

The Leeds punk rocker lived a double life, interspersing band rehearsals and punk gigs with twice-daily runs, despite the occasional arrest and moshpit injury. A new book tells his story

When Gary Devine was picked to run for England, the manager took one look at him and asked: “You’re gonna represent your country looking like that?!” Devine had turned up with shocking pink hair, holes in his jeans, a worn out band T-shirt and unlaced Doc Martens. Not that such a punky image stopped him becoming British fell running champion, after a race up Ben Nevis, the UK’s tallest mountain, in 1990. “Years later the manager told us that Gary had changed his life,” smiles Debbie Devine, Gary’s wife and coach. “He said ‘I learned not to judge a book by its cover.’”

Thirty one years on, Devine’s wonderful and often very funny story is told in a new book, Faster! Louder! How a Punk Rocker from Yorkshire Became British Champion Fell Runner. Author Boff Whalley was previously vocalist/guitarist in Leeds anarcho-punk band Chumbawamba, but is a fell runner too. “I got into it after seeing Gary win a race and recognising him from punk gigs,” he says as we all convene on Zoom. “It made me think ‘I could do that’. But Gary’s story is more extreme than mine. It needed writing.”

• Scientific review to be initiated next year
• Move follows sprinter Sha’Carri Richardson’s ban in June

An advisory group to the World Anti-Doping Agency (Wada) will review whether cannabis should remain a banned substance, a move that comes after American track and field star Sha’Carri Richardson missed the Tokyo Games after testing positive for it.

The scientific review will be initiated next year, Wada said on Tuesday. Cannabis is currently prohibited in competition and will continue to be in 2022, it added.

• Burundian runner breaks 2,000m world record in Zagreb
• Niyonsaba is an athlete with difference in sexual development

Track and field history was made in Zagreb on Tuesday night as Francine Niyonsaba became the first athlete who has identified herself as having a difference of sex development (DSD) to officially break a world record.

The Burundian did it in style, shattering the old 2,000m best by more than two seconds as she crossed the line in 5:21.26. While the 2,000m is not run frequently, Niyonsaba’s performance will inevitably reignite the debate over athletes with DSDs, given they are barred from competing internationally between 400m and 1600m unless they take medication to reduce their high testosterone.

• CJ Ujah’s B sample tests positive for two banned substances
• UK Sport admits to ‘concerns’ about crisis in athletics

A wretched 24 hours for UK Athletics continued on Tuesday when CJ Ujah’s B sample confirmed his positive drug test at the Tokyo Olympics. It now seems increasingly likely the Team GB men’s 4x100m team will be stripped of their silver medal.

Separately UK Sport has admitted to having “concerns” about the crisis in British athletics, which led to several Team GB stars asking Sebastian Coe to save the sport in this country when they met him last week in Zurich.

• UKA chief executive and performance team face criticism
• Athletes raised issue with World Athletics president in Zurich

Several of Britain’s top track and field stars have told Sebastian Coe they are at breaking point with the current regime at UK Athletics and have made a plea to him to intervene.

Multiple sources have told the Guardian that several of GB’s leading athletes confronted the World Athletics president while in the Crown Plaza Hotel after the Diamond League finals in Zurich – and he was made aware of their disillusionment with UKA.

Christine Mboma knows the faster she runs the clearer her advantages with difference in sex development become

Christine Mboma runs the 200 metres like no other elite sprinter in history. Her start is sluggish. Her drive phase needs work. But then her legs begin to whirr … and suddenly whoosh! One, two, three, four opponents are picked off. At the Olympics she flew from fifth with 50m left to win a silver medal. Last week she also added the Diamond League title in an Under-20 world record of 21.78 sec. What makes the 18-year-old’s achievements remarkable, aside from her age, is that she only began focusing on the 200m in July.

Given time, and better technique, Florence Griffith Joyner’s world record of 21.34 sec will fall. Yet Mboma is also increasingly faced with a devilish catch-22. The faster she runs, the more she provides evidence that she has an unfair advantage as an athlete with differences in sex development (DSD). Francine Niyonsaba, who won the women’s 5,000m Diamond League final has a similar dilemma.

• Sprinter states world, Commonwealth and European aims
• Keely Hodgkinson also eager to take on trio of tournaments

Dina Asher-Smith is determined to make up for lost time by going for gold in the world championships, Commonwealth Games and European championships over a hectic five-week stretch in 2022.

With the pandemic decimating the calendar in 2020 and a hamstring injury robbing her of an Olympic dream in 2021, the British 100m and 200m record holder plans to defend her world 200m title in Eugene in July 2022, compete in the Commonwealth Games in Birmingham a fortnight later, and then try to retain at least some of her three European titles in Munich in August.

• Sprinter second behind Elaine Thompson-Herah
• Britain’s Keely Hodgkinson wins 800m gold in Diamond League

After a season drenched in tears and heartbreak, Dina Asher-Smith went toe-to-toe with the greatest women’s sprinter in history – and reminded everyone just what she can do when her body is firing and pain-free.

On a raucous and joyous night in Zurich, a crowd of nearly 30,000 roared Asher-Smith on as she flew out of the blocks and led the double Olympic champion Elaine Thompson-Herah for 50m, before the Jamaican found a fifth and sixth gear to power home in 10.65sec – the eighth fastest in history – to add the Diamond League 100m crown to her collection.

• Jamaican sprinter recorded second-fastest time last month
• Thompson-Herah will compete in Diamond League final

The double Olympic champion Elaine Thompson-Herah has the talent, the track, and the conditions to finally break Florence Griffith Joyner’s 100m world record at the Diamond League final in Zurich, her fellow sprinter Andre De Grasse has predicted.

A fortnight ago Thompson-Herah ran 10.54 sec in Eugene – the second fastest time in history and just 0.05sec off Flo-Jo’s record. And De Grasse, who won 200m gold in Tokyo, believes it is possible she can make history given the warm weather and the newly resurfaced track at the Letzigrund Stadium.

• Asher-Smith third in 200m with a time of 22.04 in Brussels
• ‘It felt so good to be here and to be able to run this fast’

Dina Asher-Smith was delighted after running a season’s best time at the Brussels Diamond League – but still had no answer to the 18-year-old sensation Christine Mboma, who finished powerfully to claim a stunning 200m victory.

Asher-Smith, whose Olympic gold medal dreams were cruelly ripped from her when she injured her hamstring in June, led from the blocks and was second behind the Jamaican Shericka Jackson with 75m to go.

• China finished second but disqualified for illegal handover

• Libby Clegg announces retirement from competition after race

An upgraded silver medal in the inaugural ‘Universal’ 100m relay race capped a strong day on the track for ParalympicsGB as the team reached a total of 110 medals, and reclaimed second spot in the table.

Three mixed gender relays were added to the programme for the Tokyo Paralympics, with the first two taking place in the pool and proving a hit, with a new variation on racing dynamics. On Friday it was the turn of the sprinters to mix it up, with Britain fielding a team comprised of Paralympic champions Libby Clegg and Jonnie Peacock alongside T38 class sprinter Ali Smith and wheelchair racer Nathan Maguire.

• US athlete banned for four years in June after positive test
• Houlihan said she ingested nandrolone from contaminated food

The probability that a contaminated pork burrito led to the US Olympic 1500m medal prospect Shelby Houlihan’s failed drugs test is “very close to zero”, the court of arbitration for sport has ruled.

In a 44-page verdict, which outlined the reasons why Houlihan was banned for four years in June, Cas said her claim she had unwittingly ingested the banned substance nandrolone by eating the meat of an uncastrated boar from a Mexican food truck “simply cannot be accepted”.

• British athlete takes bronze in the men’s T20 400m
• GB hit 1,000 Olympic and Paralympic Lottery-funded medals

“That was hard,” said Columba Blango. The heat had broken and the rain was coming down on the Tokyo Olympic Stadium, but in only the second international competition of his career the 29-year-old from Peckham Primark had won a bronze medal.

“It’s my first Paralympic Games, so I plan to make more Paralympic Games in future,” he said. “I can take this experience with me knowing that I’ve actually done something, so this is major on my part as well.”

• British T64 sprinter finishes level with Johannes Floors
• Felix Streng takes gold and Sherman Isidro Guity Guity silver

The clock ticked past three minutes and still there had been no decision. The men’s T64 100m had certainly been close, with the four leading competitors finishing within four hundredths of a second of one another. But who had claimed bronze between the German Johannes Floors and Britain’s Jonnie Peacock?

The rules determine that only in the event of a gap of less than 1,000th of a second would two athletes share a place. When the photo finish was eventually called, that was exactly what happened.

After a Richie Tenenbaum-like unravelling on and off the track, it’s fair to wonder whether the American sprint star will be remembered more for running her mouth than running at all

Mujinga Kambundji. Javianne Oliver. Barbara Pierre. They are but a sampling of the women who have brought up the rear in the 100m dash at the Prefontaine Classic in recent years. If those names are news to you, it’s probably because the TV networks tend not to go out of their way to spotlight the biggest losers.

The notable exception of course came during last Saturday’s edition of the Pre, a hotly anticipated Diamond League showcase that would mark the return of Sha’Carri Richardson from a monthlong, THC-triggered drug suspension that cost her a spot in the 2020 Olympics – and on the same Hayward Field where she stole hearts from Eugene to Yokohama after clocking a 10.86 to win the US trials. What’s more, Richardson would be going toe-to-toe with Elaine Thompson-Herah, Shelly-Ann Fraser-Pryce and Shericka Jackson – the fearsome Jamaican trio that locked out the 100m podium in Tokyo.

Elaine Thompson-Herah came within 0.05 seconds of Florence Griffith Joyner’s 33-year-old 100m world record as she clocked the second fastest time ever at the Diamond League meeting in Eugene.

The Jamaican blazed to victory at the Prefontaine Classic in 10.54sec, eclipsing the 10.61s she ran to defend her Olympic title in Tokyo last month.

• British athlete tested positive for two banned substances
• ‘It’s better to look closer to home before attacking others’

Italy’s Olympic sprint champion, Lamont Marcell Jacobs, said he smiled after hearing that the British sprinter CJ Ujah had been provisionally suspended for an anti-doping rule violation.

Surprise has been expressed at Jacobs’s performance in Tokyo, mostly by the British media, after he became the first Italian to win a 100m Olympic gold medal. Jacobs, 26, was the seen as an underdog before he powered to victory.

• Ujah was part of Team GB’s 4x100m relay team in Tokyo
• 27-year-old faces prospect of being stripped of his medal

Chijindu Ujah, the British sprinter who won a silver medal at the Tokyo Olympics as part of Team GB’s men’s 4x100m relay team, has been suspended for a doping violation, the Athletics Integrity Unit has revealed.

Ujah is one of four athletes who tested positive for a banned substance at the Games and who were named by the AIU on Thursday. According to the AIU, Ujah has tested positive for S23, a SARM (Selective Androgen Receptor Modulator) which aids muscle building and Ostarine, another SARM which is not a steroid but an anabolic agent.
