IAAF 4×400 Meter Relay Split Times from Beijing 2008

How were these splits recorded?

Transponder antennas were laid under the track at the 0m, 100m, 200m and 300m. Athletes wore chips on the inside of their front bib numbers, so when they crossed the transponder threshold, a time was registered.

This sound similar to RFID chips attached on shoes for distance events with the tracking pad at the start and finish line.

Unfortunately, we do not have accurate 10 meter splits for the 100 meter sprints. For now we’ll have to rely on video analysis for the 100 meters and 200 meters. Let’s hope in 2012 these will be in place.

The data was derived by ST SPORTSERVICE GmbH, a service by Swiss Timing. The following results gave actual (3rd and 4th legs) and estimated (1st and 2nd legs) times for all runners in the 2008 Beijing Olympic 4×400m relay races (Men’s and Women’s).

For the first and second legs, the time given is an estimate (denoted with an “e”) based on photo-finish time at the finish line by first leg runner before stagger on the 3-turn stagger. The third and fourth legs times are computed from photo-finish pictures of the baton holder at the finish line.

This is the correct method for taking splits in any relay: when the baton crosses the line, not where the baton is exchanged.

    In februari you may not know Jonathan Borlée but now you should know him already.
    He ran a belgian record of 44.78 to win the NCAA final this season…
    Unfortunatly he’s unable to compete in Berlin due to injury.

    @Zephirin - yes, I was wondering why only Kevin Borlee was listed in the provisional entry list.

  3. Zephirin Joachim on August 12th, 2009 1:11 am

    Well Jonathan has a stress fractue at his foot and won’t be running anymore this season.
    But be well aware of the fact that Kevin was good for 44.88 (the previous BR) at the Beijing semifinal. Good for the eight fastest time from those semis but unluckily missing the final.
    So watch out for him at Berlin…

Got something to say?
