Berlin 2009 200 m men’s final

Tuesday, August 18th, 2009
When and what time does 200 m final men’s in Berlin 2009
The final 200 m men’s race is scheduled for Thursday, 20 August 2009 20:35 (Berlin local time – CEST) [11:35 AM PDT, 2:35 PM EDT]

Usain Bolt’s amazing 100m world record shows that he is the fastest man in the world ever. Is he able to break the 200 m world record? Let’s try to predict Bolt’s time in 200m final race in Berlin 2009.

Bolt’s speed and time prediction during the final 200 m race in Berlin 2009
Usain’s Bolt average speed in the winning 100m men’s race was: 100m/9.58s = 10.43841 m/s (23.3501mph). So, if he can run 200 meters with this speed, he can get the time 200m/10.43841m/s = 19.16s !!! (his current world record is 19.30s) but, as we look at previous world records (see table below), average speed on 200m distance is faster then during 100m race, so we can expect even better result.

As we can see, 200m distance speed is about 0.4-0.6% faster then on 100m distance. So, expected Bolt’s speed could vary beetween 10.43 m/s and 10.50 m/s. It gives us amazing times between 19.175s and 19.048s. I, personaly, think that Usain Bolt is able to run 200 m in Berlin in about 19.15s
