London Olympic Games 2012 Belgian track cycling Evaluation

4.02.317 BR WK Melbourne 4.04.056 OG London 2012

The athletes started their preparations for the Olympic

games at an altitude training camp in Spain in September

2011. It is proven that from these aerobic gains that it was

beneficial for the team to further their training intensities

at frequent intervals at altitude up until the Olympic

games. The aerobic base proved both in tests and in the

race itself to be a success with the team splitting

consistently 3km each at 59seconds throughout the race .

Why then was the time off pace from the targets set to try

and break the four minutes?

•Why did the team go out too slow?

•Why did the pace not get picked up from Cornu in 4th

position?

•Why did Cornu not ride 2laps ?

•Why did De Ketele stay on a full lap when the coach asked

him to do half a lap?

The following report is important to see that the gear was

influential in trying to achieve 3.59. Without this correct

gear the team would falter due to too high revolutions, too

high heart rates and not targeting the correct power

delivery. Crucially the team needs to be launched into its

efforts at the right speeds during the opening km to stand

any chance of achieving the target.

The comparison between

April and August , a

confirmation that the

athletes were in

condition and ready to go

under the magic four

minute barrier. What

exactly went wrong and

why the team effort was

dictated by a slow start.

The steptest proved again to be crucial in confirming the condition and also importantly showing the progression made in both the aerobic and anaerobic energy systems


Training evaluation and confirmation


Anaerobic work was detrimental in realising the top end speed and this file shows that the athletes built always correctly into their training sessions with a routined warm up using 2 to 3 5km building through 5.20 on 10’minutes

Standing 3km race pace


During the last preparation training camps and running into the last few days of the taper, standing start race pace simulations were key to confirm that the gearing was good and that freshness was coming into the athletes which means speed and full faster recovery. The signs were excellent and the boys felt very good.

Here is the predicted pacing Standing 3km for 3.58 which was realistic. Opening 1.04 – 2.02 – 2.59 – 3.58

Realised pacing 1.04 – 2.01 – 2.59

Note how the tempo is maintained and power delivery is correct.

Last block on front from standing 3km. Showing good pace on 2.59 schedule


The gearing here is 100% correct. Any smaller there would be problems with cardio-vascular intensity in the drafting/wheel recovery.

Race day, morning effort. Again a very good correct example of the warm up. Then the preparation interval demonstrates an excellent form.


Race pace check morning more than 5hours before the start


Super, on track to realise target.

Race DC


Race KDK

Training standing 3km

Note the poor start which leads into a very bad transition of power delivery thorugh out the team . 130rpm in training same gear same simulation, 125rpm in race and 89watts different power output which is massive.

Also Kenny starts in simulation with 1200watts and only pushes 1150watts in the race which is lesser than Cornu and Cornu is 4th man. No wonder that the whole team were back pedalling

1.04.572 London world cup opening km 1.04.025 Melbourne opening km 1.04.1 London standing 3km training 1.05.461 London Olympics opening km

Note however in the film that the coach says “goed zo” as the renners come through the first km! Also the coach shouts for De Ketele to ride half alap after 3km but he does a full lap!

In the film also big fault in the finish. Way to early up and not racing for the line.

The gearing decisions were dominated by both the feedback from the athletes as the proof on the srm files that the current form that the boys had was realisitic in realsiing their goals. Any smaller would have meant riding for 4.03 or 4.02 which of course with hind sight would have been enough to confirm their time of the world championships. However the athletes were better physically prepared for ther Games than the world championships proving in training tests both individually and as a team.

This failure in performance has to be strongly linked to mentalitity and scared to fail in front of a world wide audience. In the world championships in Melbourne Kenny De Ketele also started but their ambition proved to be greater than here at the Olympics. Kenny was dropped after 3km in Melbourne and obviously in London didnt want to start as quick risking what he would see as humiliation.

Points race

Again wasting energy at the end. An effort that changed nothing.

Elimination


Here we see a problem area towards mentallity and arrogance. Starting at the back there was no indication in the video or files here that Gijs tried to move up. The increase of cadence is only due to peleton speed increase. Normally with this gearing in the sprint Gijs can realise + 147rpm and +1000watts. He mentally literally eliminated his chances of performing at the Olympics.

Here he gives up in the home straight and does not pedal with force

This is good an area that has been worked on alot, but the transition can still be better. Gearing was good an optimal for achieving a solid start.

Strong finish

One of the best points races ever from Jolien. Normally a weak point of her Omnium. Read the race well, used her energy efficiently which has not been the case in previous races. Lesser max peaks which is good to see. Gaining a lap proving mental strengths gained.
