With a tailwind, how fast could Derval have gone in Barcelona?

    She ran 12.65 into a -0.5 headwind in Barcelona.

    If she had say a 0.5 tail wind how fast would she have gone?

    If she had a 2.0 tail wind how fast would she have gone?

    Trying to compare her performance to those of Perdita, Sally, Priscilla, Lolo etc and how her time stacks up against those. But Derval's time was into a headwind so isnt a fair comparison.

    Maybe slower don't think this event does a huge amount better with a strong tail wind, makes it harder to judge your race and you come tothe hurdles too fast....well thats according to Colin Jackson.

    Depends as some hurdlers can run better into a slight headwind. It can mean you aren't as close to the hurdle and you can attack it more. A strong tailwind can see you too close and going too high over the hurdle to avoid hitting it.

    Interesting point.

    Berlin last year she ran 12.67 with a 0.2 tail wind, and this year 12.65 with a -0.5 headwind. How much would that 0.7 wind differential have made? How fast would she have run if she had the same wind conditions that she had in Berlin (not very windy)? Would it be no more than 2-3 hundreds of a second?

    There are more factors than wind at play. Temperature, humidity, altitude and track surface all play a part, too. Assuming the tracks were similar, and so were the altitudes and temperatures, the only significant difference is in the humidities: 32% for Berlin and 65% for Barcelona. How much advantage does that give Barcelona? No idea.

    Just based on the wind readings, Derval might have gone 0.02 quicker, if even that. Low wind readings, less than about 0.5 m/s, make almost no difference.
