Having personally been captivated by Rudisha’s 800m performances earlier this year, breaking and re-breaking the world record, I recently found this video of him going 46.5 in the 400m back in February with a short interview that follows.
Excellent find James. Not sure if you saw this from KK in the Analyse this thread
[i]I received the following message from James Templeton, agent/manager for David Rudisha and most of Brother Colm O’Connell’s athletes over the last decade. This note refers to David’s 45.50 in Sydney in late February 2010 and the 1:43.1 in Melbourne a few days later in early March this year:
"It went pretty well mate!! Jesus he looked good; passing 400 in 50-low (Sammy 50.00) looking like he was running a 15km road race!!! I’m pretty excited about the summer…to now he’s just been doing base training – steady runs, fartleks, strides and a couple of time trials. A track session last week was 2 x 400 in 57, 3 x 300 in 41 and 3-4 x 200 in 25. So it’s nothing specific as yet; the 45.5 and the 1:43.1 are just on good solid fitness and natural talent…
It’s hard to imagine him not putting a real challenge on that 1:41.11 in the summer. Maurie thinks he’ll challenge the 1:40 barrier. Now that would be something…
An 800m runner who probably has sub 45.0 potential for the 400, incredible.
Based upon the perceived relaxation he maintained in Rieti while re-breaking his WR he definitely has my confidence in him going sub 140.
In Berlin the rabbit cut 48.65 for the first 400. That translates to 8.22m/s. Rudisha looked to be 2 - 3m behind so let’s say he went 48.89-49.01. Going 141.09 for the 800 gives him 52.08 - 52.2 for the 2nd 400
139.98 translates to 49.9 splits
I say he does it
If I’m his coach I aim for increasing his speed to 45 low or even sub 45 for the 400 and his speed reserve will cover the spread
