London Marathon 2017: Self-coached club runner Josh Griffiths pulls off huge shock as fastest Briton

A self-coached student who travelled by London Underground to the start line produced one of the biggest shocks of recent London Marathon history on Sunday, finishing as the fastest Briton to secure an unlikely place at the World Championships this summer.

Attempting the first marathon of his life, Josh Griffiths, 23, was not even part of the elite field and started behind the leading athletes with his fellow club runners.

Anonymous to most spectators thanks to the number 1154 on his bib – unlike the elite runners, whose names adorned their chest – Griffiths slowly gained ground on various Olympians and seasoned international runners, passing the overwhelming majority and crossing the line in some disbelief in a time of two hours 14 minutes and 49 seconds to finish 13th overall.

On a day that saw a scintillating Mary Keitany break Paula Radcliffe’s “women only” marathon world record, Griffiths’ performance was a surprise to all – even British Athletics officials had to ­admit they knew little about the man studying a masters in sports coaching at Cardiff Metropolitan University.

Having won a humble park run in a Welsh village two starts ago, Griffiths will now represent Britain in the marathon at this summer’s London World Championships.

“I stayed with my parents in London last night,” said Griffiths, who lives in the village of Cross Hands in west Wales. “I was in London Bridge train station at 6.45 this morning, got the Tube to Blackheath and stayed there until the start.

“We started about 10m behind the elite field, but obviously that was never really in my mind to race those guys. I just wanted to run my own race.

“Once I got to halfway I started to catch the elite British guys up and I was running with people I’d looked up to.

“I couldn’t quite believe it and then, all of a sudden, I was pulling away from them.

“Until I crossed the line I didn’t quite believe what had happened.”

While most elite athletes spent the winter on warm-weather altitude training camps, Griffiths was busy tackling the hills of rural Wales in preparation for a debut attempt at the marathon distance.

“I coach myself and I just train around the house really,” he said. “It’s quite hilly – I’ve got some nice cycle paths to train on.

“I did a half marathon last month and that told me I was ready to run well but, because this is my first marathon, I never really knew what to expect. To run this is beyond my wildest dreams.”

Another relative unknown, Daniel Wanjiru, claimed overall victory, with the Kenyan holding off a late charge from the great Ethiopian Kenenisa Bekele to triumph in 2hr 5min 48sec.

The $4,000 prize may be the biggest of Griffiths’ career, but it pales in comparison to the $125,000 world-record bonus Keitany takes home to Kenya in addition to $55,000 for winning the race.

Already a dual winner of the London Marathon, she set off at what appeared to be a suicidal pace, dropping the entire field after barely two miles and heading off into the distance with only a pacemaker for company.

At the halfway stage she was more than a minute ahead of Radcliffe’s outright world record of 2hr 15min 25sec, which was set in a mixed race with male pacemakers.

While that mark gradually slipped away over the second half of the race, Keitany had a second target in her sights – Radcliffe’s “women only” world record of 2hr 17min 42sec.

Despite running more than 13 miles in solitude after the pacemaker dropped out, Keitany maintained her gruelling pace to win in 2hr 17min 01sec.

One year after her fellow Kenyan Jemima Sumgong took victory, only to be disqualified for failing a drugs test, Keitany’s performance is bound to raise eyebrows despite her scathing criticism of her former team-mate.

“There is a saying: ‘In every maggot there is a madman or a madwoman’ so I think in sport there are those who are cheaters and those who are clean,” she said.

“Most of us in Kenya are talented by nature. I want to end my career clean. I ran an amazing time that I have never run before so I am happy.”

Moving third on the all-time list behind Keitany and Radcliffe, Ethiopia’s Tirunesh Dibaba failed in her effort to chase down the winner but finished an impressive second in 2hr 17min 56sec.

Jo Pavey had been hoping to come among the top two British women but said she was “bitterly disappointed” to drop out after 16 miles with leg cramps.

That left Alyson Dixon to cross the line as the leading home nation woman in 2hr 29min 6sec and ­secure her place at the World Championships alongside Charlotte Purdue, who was 17 seconds behind her.

Reports to follow

Our live coverage is coming to an end, but for many their race is only half done. I'll leave the last word to them, an inspiration and kick up the backside to the rest of us.

 And a reminder of how important the support is from those of you out there cheering them on:

Time to get behind the man running with a washing machine on his back. Keep it clean.

12:30PM

Men's winner Daniel Wanjiru

In the beginning the race was very fast. I was prepared for any pace, but anything can happen when the race is that fast. We were talking about the pace at the start, which we tried to maintain until halfway. From there it got tougher and tougher. The sun came out, we didn't need that. But the race was great for me. I was comfortable at the pace we were running and that the world record is possible; anything is possible.

12:28PM

Mary Keitani, world-record setter

It was a great day for me. I ran all the way as the pacemaker. I thank God for giving me this opportunity. It was really amazing because I was ready to run my career best time, but to have two runners run under 2:18:00 was great. It is amazing that I ran 2:17:01.

12:26PM

And Chewbacca is going well, you'll be glad to here.

A triumph for club runners

Josh Griffiths, a club runner, has blown away the British front runners to top the home contingent with a phenomenal time of 2:14:49. Who saw that coming? Could he represent Great Britain in the World Championships in London this summer? He's secured the qualifying time.

Robbie Simpson is the second Brit to finish, also coming in within the qualifying time.

The commentary team is unabashedly biased towards Bekele. I know he's a legend and all, but that's not Wanjiru's fault, poor fella. I'm going to get behind him just to add a bit of balance.

"It's about who wants it more at this stage," says Radcliffe. You've got to want it, Wanji.

Ben Bloom reports on David Weir's triumph in the men's wheelchair race

You can read the full reporter here. But how about a teaser?

Hugging the back wheel of his great rival Marcel Hug through the streets of London on Sunday, Weir opted not to pass the Swiss athlete until 200 metres remained, outsprinting him down the Mall to triumph in one hour 31 minutes six seconds.

Despite some suggestions that he could retire after completing an 18th consecutive London Marathon, Weir now appears likely to continue his road racing career.

11:37AM

Keitany’s unofficial time and the new women-only world record, is 2:17:01.

Alyson Dixon and Charlotte Pardew look like they will be the top two British finishers and heading to the World Championships. It's now just a question of whether Pardew can run down Dixon.

11:35AM

Mary Keitani smashes the women's-only world record

Just on the stroke of 2:17:00. Waiting on official timings. But that is the women's-only record regardless.

Tirunesh Dibaba finishes second just under 2:18:00.

Mary Keitani on for the women's-only record time. When City marathons started off, the women would head out with the men, using their assistance as pacemakers. Paula Radcliffe holds the mixed race record, which is no longer under threat. 

11:25AM

Karoki time

Kenyan Bedan Karoki is a half-marathon specialist and many were keen to keep a close eye on his full Marathon debut. He's going strong:

11:23AM

Kenenisa Bekele really struggling now

He's dropped back from the back entirely and is running a lonely race at the moment. It doesn't look like we'll be getting a world record in the men's race now.

Keitany down towards Big Ben. Tirunesh Dibaba clutching her stomach, she might have cramp. That could be her challenge over, slowing to a walk as she is.

Timings for the top two British women as they stand:

11:19AM

BritWatch

Alyson Dixon running  a personal best and leading the battle among the British women in 12th place overall. Charlotte Pardew only 15 seconds behind. Jo Pavey in fourth among the Brits.

A reminder that Pavey needs to finish as one of the top two British women and run a time of two hours and 36 minutes or better to secure qualification for the 2017 World Championships. That's looking like a tall order as it stands.

Dixon

11:16AM

Keitany tiring

Her last mile was a 5:29, so that's down again on her early pace. She is, however, now over a minute ahead with under 3.2 miles to go. 2:01:00 currently on the clock.

"So far so good."

Says Steve Cram of Kenenisa Bekele's race. The long-distance legend is in the leading pack of around ten or so runners. They're now coming over Tower Bridge.

Bekele

 I do wish they'd slow down so I can take a decent snapshot.

10:55AM

Can she break the record that counts?

10:53AM

Keitany still way out in front

Tirunesh Dibaba currently in second, a fair way off the pace. Keitany still leading, despite slowing up. Her predicted time has slipped to 2:15:08, which is still world record pace, but Cram doesn't think she'll make that. Dibaba in with a chance if she "continues to run strong," says the former British distance runner.

Still no news on Mr Potato Head. Presumably he's full of beans, so he'll be fine.

An inspirational story

As the elite's get into their stride, it feels like time to take a look at some of our everyday heroes. Jim White's interview with Somalian Zamzam Farah (a good long distance name if ever there was one), whose journey from war-torn Mogadishu to the start line of today's London Marathon is a truly remarkable one.

“We didn’t have a proper track, just sand marked with whitewash for races,” she recalls of the facilities locally. “When you fall down, you get injured. We had nothing proper.” 

What is more, her coach was also targeted by fundamentalists. “It was tough for him. He was getting trouble because he was coaching a lady.” 

Nonetheless, Ali believed in her, admired her determination, her refusal to be cowed by smothering convention.

Britain's Jo Pavey will aim to secure qualification for the 2017 World Championships today.

She needs to finish as one of the top two British women and run a time of two hours and 36 minutes or better.

The women's race has been shrouded in controversy: last year's winner Jemima Sumgong is absent after testing positive for a banned substance.

You can read Ben Bloom's take on that and other matters in the elite events here. For now, a taster:

It is amid a backdrop of more than 40 Kenyans caught committing doping violations over the past six years that several leading runners from the east-African powerhouse are ready to step into Sumgong’s shoes this Sunday.

Meanwhile, athletics fans are left trying to convince themselves to believe what they see.

Marathon horror stories

Not to dissuade anyone running today, but here are a few things that can go pear-shaped on Marathon day, including thermometers in uncomfortable places:

London Marathon 2017 - all you need to know

What is it?

Why, it's only the 37th edition of the long-distance race around the streets of London which is tackled by both elite athletes and amateurs who regularly run the 26 mile and 385 yard course – or 42.195 kilometres for the Europhiles among us – for charitable causes.

Incidentally, the fastest ever time the course has been run in happened in 2016 when Eliud Kipchoge of Kenya completed the route in two hours three minutes and five seconds. 

Paula Radcliffe of Great Britain set the fastest time for a woman back in 2003 after putting in a two hour 15 mins and 25 secs shift on the streets of London.

When is it?

All races take place on Sunday April 23, 2017. First up, the wheelchair race starts at 8.55am (BST) and will be followed by Paralympic runners at 9am whose race is part of the IPC Athletics Marathon World Cup.

The elite women's race gets under way at 9.15am before, 40 minutes later, the men lead out the tens of 1,000s of amateur runners.

How long until the 2017 London Marathon starts?

What TV channel is it on?

The London Marathon will be broadcast live on BBC 1, with their programme starting at 8.30am.

What does the weather forecast look like for Sunday?

For the runners the weather is looking perfect, possibly a little chilly for anybody planning on heading into central London to cheer them on. 

Here's what the Met Office have to say: "A mild, but not hot, day with a light breeze will help those charity runners who will still be completing the course past noon.

"Those conditions will also help the professional runners get around the course in world-record time  as we saw in 2002 when Khalid Khannouchi shaved a few seconds off his own world-record."

How can I track a specific runner?

Official app and online tracker

The Virgin Money London Marathon ran its own mobile app for the first time in 2015, to make it easier for friends and family of participants to track the race as it progresses

This year is supposed to be the first time the service will be available on Android, having previously been an iPhone exclusive.

The tracking facility is also accessible via the official website - though it is currently inactive, pending the race start. Timing intervals are every five kilometres and you can search both by a runner's name and their race number.

The app still appears to be only available on iPhone, so Android users will have to head online or use other running apps.

The official app and online timing uses the chips given to each runner, but only delivers estimated positions every five kilometres.  If you want more specific feedback, it is worth exploring other options.

Running apps

There is a range of other apps available on both Apple and Android that use GPS tracking and automatically deliver live updates to followers online.

These smartphone apps can provide more detailed and personal way to follow a friend than the official website. Set up before the marathon starts, the smartphone will send progress reports via email and social media throughout the race.

Some of the running apps are free, but to access the live-tracking facilities with the likes of Garmin Fit and RunKeeper you’ll have to sign up for the paid subscription service. 

To avoid the battery running out mid-race, make sure you pull back to the Home screen so that the app is only operating in the background.  

It’s also best to be aware that during past London Marathons, these mobile means of tracking have had problems with overload.

Arithmetic

If you’re out on the course looking to spot a specific runner, you can also use good old-fashioned mental arithmetic to ensure you’re in the right place at the right time. 

Provided your charge has done a modicum of training – enough that they can take a stab at their average minutes-per-mile – and you know what time they start, you can make a fair guess what time they’ll hit each mile marker around the course. By Sean Gibson
