This post on the BBC Sports website http://news.bbc.co.uk/sport2/hi/athletics/7854443.stm caught my eye. This is
very interesting and I believe useful information. It has always been my
contention that American middle distance and distance runners do not train the
way they have to race. In order to do that you have to know how races are won
and conversely lost at the world class level. This type of information can
help. I am working with a company that has developed a more sophisticated monitoring
system that can provide more detailed information, especially in multidirectional
sports. The goal is to train for the game or the race.
How Olympic Finals Were Won or Lost
By Mark Butler
BBC Sport's athletics statistician takes a look at the
numbers behind the big races
|
If you are a casual runner testing your fitness, try measuring out 100
metres and see how quickly you can cover that distance.
Then compare your result with the following figures: 15.4seconds for men and
17.3 for women.
For many fit people, these might not seem to be tough targets and of course
are far from the current world records of 9.69 and 10.49.
But consider that these were the slowest 100m sections covered in the
respective Olympic 1500m finals last summer.
Every athlete in both those races ran 14 further 100m stretches faster than
those times, and without a break!
These figures were obtained from a revolutionary timing system, where all
distance running athletes each wore a tiny transponder on the inside of their
front bib number.
Each time the runner passed over the 100m, 200m, 300m or 400m point on the
track, his or her time was registered.
Therefore in the men's 10,000m with 35 finishers, some 3,500 separate times
were recorded.
It was all a bit too much to take in at the time, but now we have had a
chance to take stock, can see a unique picture of how and when races were won or
lost.
Among the highlights:
· A fast back straight, rather than finishing
burst, clinched victory in many races.
· Britain's Lisa Dobriskey may not have made
the tactical error many believed in finishing fourth in the 1500m.
· Women's 10,000m champion Tirunesh Dibaba ran
a section faster than Britain's Mo Farah in his heat of the men's 5,000m.
KILLER BLOW
In finals it is interesting to note that none of the new Olympic champions
ended their race with their fastest 100m. The damage had been done before that
point.
Not surprisingly, the 800m races provided the fastest movers. Two of the
800m men clocked a time of 11.7 down the back straight on the first lap in
their preliminary races, but both went on to be eliminated.

Conversely, Canada's Gary Reed left it too late. Seventh at 700m, he
finished the Beijing final with a blistering 12.3 but ended up a frustrating
fourth.
In the women's 800m, the figures confirm the trademark move of the new
champion Pamela Jelimo: a big effort on the final back straight.
The Kenyan clocked 14.2 for the section between 500m and 600m before slowing
to 15.2 then 15.6. When Kelly Holmes won in Athens she finished faster than
that, but from a slower initial pace.
Rashid Ramzi ran a tactically perfect race to win the men's 1500m, with a
scorching 12.6 on the crucial final bend.
His taller rival, Kenya's Asbel Kiprop, clocked 12.8, which proved the
difference, even though Kiprop was the faster in the finishing straight and
closed to within 0.2 secs of the Bahraini.
Of course the figures alone cannot tell the story of the race. Someone
forced to run wide on a bend would be actually be running further than 100m
between the two transponder points.
In the women's 1500m it was widely felt that Lisa Dobriskey had lost a medal
through poor tactics, but the timing analysis does not fully confirm this.

In finishing fourth she ran a faster last 100m (14.6) than all but one of
the other finalists, but the one quicker was Ukrainian Natalya Tobias, who Lisa
had been tracking all round the final lap and who took the bronze medal.
Would they have been able to finish so fast if they had covered the
courageous breaks made by winner Jebet Lagat (14.3 to 1100m) and silver
medallist Irina Lishchynska (14.5 to 1200m) earlier in the race?
We'll never know. We do know that it did not work for Bahrain's world
champion Maryam Jamal, who finished with only 17.2 after leading at the bell.
Kenenisa Bekele and Tirunesh Dibaba each won the 5000m and 10,000m double
and the statistics show that they won with similar tactics at the finish.
It is as if they take delivery of fresh legs in the closing stages of their
races.
In the men's 10,000m, Bekele simply changed gears 500m from home, moving
down from 15.1 to 13.9 to 9600m and 14.0, 13.2, 12.5 for each successive 100m
then 13.7 easing off.
Bekele was even more impressive at the 5000m, with three consecutive 100m
segments under 14 secs from the bell.
In the brutally quick women's 10,000m final, "Dibaba the Dasher"
was able to run the final back-straight 100m in an astonishing 14 secs.
That meant she was moving faster in that section than any woman in any of
the 1500m races in Beijing as well as Great Britain's Mo Farah during his heat
of the men's 5,000m.
She had gone from 12 to 16mph in the space of 200m, which might not impress
Jeremy Clarkson but is a deadly change of pace for a woman during a long
distance race.
As with Jelimo, Ramzi and Bekele, her victory was forged before the home
straight and she was able to slow somewhat without being threatened.
Sadly the Beijing timing measurement did not extend to sprint events where
the runners all keep to separate lanes, but it is hoped that this will be
possible at future meetings.
We can therefore look forward to getting a record of the
fastest of all individual 100m runs, that of the second half of the 200m.
Also this technology can give us a more accurate picture of the seemingly
pace-perfect 400m tactics of Christine Ohuruogu.
