As the temperature climbed towards 25° Celsius, David Weir and Shelly Woods completed a home country winning double in the wheelchair races while Mara Yamauchi and Liz Yelling set the hottest pace of the GB ‘foot soldiers’ in the Flora London Marathon on Sunday 22 April.

Yamauchi summed-up: “We’ve got two men in the first 10 and two women in the first 10. Surely it shows that British marathon running is improving.”

The thermometer climbed from 14.1° (with 55% humidity) at the start of the women’s race to 16.3° (49% humidity) after an hour, 18.6° (43%) after two hours … and 20.5° after three hours, when the later-starting men’s race was reaching its testing phases.

But the hotter it got, the harder the foremost GB duo ran – with Yelling one of the few elite athletes in the race to register a personal best.

Following them down the roads, Dan Robinson and Andi Jones took top-10 places in the men’s race, surviving where much better-known athletes stalled in the heat.

And both Weir and Woods counted these successes among their best-yet performances as they prepare for the ultimate aim, the Paralympics at London 2012. 

Women’s race

On the day London’s spectators got another awesome foretaste of how successfully China is preparing its athletes for the Beijing Olympics, the home cheer was provided by Mara Yamauchi (Harrow AC) and Liz Yelling (Bedford and County AC) defying the heat to beat the elite qualifying standard of 2 hours 31 minutes for this summer’s IAAF World Championships in Osaka, Japan.

Despite not finding the fast group in which she hoped to run, Yamauchi transformed the loneliness of the long-distance runner into a lovely enough experience to finish sixth in 2:25:41 while Yelling lowered her PB to 2:30:44 for a great eighth place.

They both ran disciplined races, steadfastly ignoring the temptations to set off too quickly as the packed crowd generated the kind of frenzied atmosphere for which the world’s biggest foot race is renowned.

At the head of affairs, demonstrating this is the best as well as the biggest, Asian champion Chunxiu Zhou broke away in the 23^rd mile and finished so powerfully to become China’s first winner in London that she built an advantage of 1 minute 7 seconds over the runner-up, the renowned Gete Wame (Ethiopia). Zhou’s winning time of 2:20:38 was just 43 seconds shy of her best yet. The consistent Constantina Tomescu-Dita (Romania) was third in 2:23:55 and Salina Kosgei (Kenya) fourth in 2:24:13 as the World Cross Country Champion Lornah Kiplagat (Netherlands) faded in the closing stages to fifth in 2:24:46.

And then came Britain’s second-fastest ever female – Yamauchi, who clocked 2:25:13 on this course 12 months ago. Today she spent longer than ever in her life running on her own yet went through 5km in 16:34, 10km in 33:43, 15km in 50:48, 20km in 1:08:01, halfway in 1:11:44 in eighth place, 25km in 1:25:06, past Adere and Benita Johnson (who was to finish seventh in 2:29:47) into sixth place through 30km in 1:42:23, 35km in 1:59:56, 40km in 2:17:45.

She said: “I was pleased to come sixth again because I think it was a really good field – better than last year. And I was pleased to get close to my PB. I was not that pleased to run the whole thing on my own … but I suppose it was good for my discipline.

“The heat didn’t bother me at all which, given I want to run the Worlds in Osaka, is a good sign. The temperature will be 35°C and the humidity between 90 and 100% even though the race will start at 7am.

“I really wanted to do a quicker time today – about 2:23 – and I don’t know why I couldn’t run quicker. I went through halfway around 71:45 which was about the right speed and in my training I’ve been trying to prepare to run well in the second half. I felt quite good in the last 10km but somehow I couldn’t run faster.

“I shall have to go away and think how to run a faster marathon. It will probably involve getting my 10k and half marathon times down.”

Yelling was through 5km in 16:50, 10km in 34:07, 15km in 51:39, 20km in 1:09:45, halfway in 1:13:34 in ninth place, 25km in 1:27:29, 30km in 1:45:31, 35km in 2:04:04 in eighth place having overtaken the fading Adere, 40km in 2:22:47.

Despite her PB and high placing, Yelling said: “I’m disappointed. I really thought I could do sub-2:30. I thought 2:28 would be achievable today. I didn’t anticipate the weather being as bad as it was. Although I didn’t feel the heat, I drank a lot more than usual – I took at least a sip every mile – but I still think I didn’t drink enough.

“My calves were cramping. People are saying that’s why a lot of runners dropped out. I had a nightmare a fortnight ago because my calf went into a spasm. I phoned Zara Hyde Peters [the Director of Athletics Performance at UK Athletics] and she was very, very good. She arranged for me to see Dr Bruce Hamilton. And physios Mark Booth and Mark Buckingham has been invaluable over the last couple of weeks. In addition Martin [her husband] has given me a massage every day for the last two weeks just to get me to the line.”

Why didn’t she mention this pre-race? “Because I didn’t want it to be an excuse. I didn’t want people to think, ‘Aah, Liz has had a tough time’ I just wanted to get on that start line equal with everyone else.”

Husband Martin had promised her a ‘champion’s dinner’ if she ran a PB – and, in truth, both earned the slap-up meal the hard way. Martin was forced to drop out at 18 miles when his quads tightened up.

Kathy Butler (Windsor, Slough, Eton and Windsor AC), who ran 2:28:39 in Chicago last year to register a World Championships qualifying time, went through 5km in 16:51, 10km in 34:25, 15km in 52:02, 20km in 1:09:48, halfway in 1:13:38 in 10^th place, 25 km in 1:27:42, 30km in 1:47:10 in 11^th place (she was overtaken by European 10,000m champion Inga Abitova) but then joined the growing number of athletes to step off the course.

Butler, who had done much of her training in snow at her USA base, said: “I think it must have been the heat. All of a sudden I went from 5:40 miles and passing people to 6:10 and wondering what was happening. I wasn’t sweating very well. It’s been quite cold where I’ve been. Not that it was super-hot here – just warmer than I’ve been used to.”
