Which is better for running – hot and dry or cold and wet? Personally, I’d prefer the heat but statistically it seems that the colder, wetter weather is better for finishing times. Last year’s BMO Vancouver marathon was the hottest in the race’s 42 year history (with temperatures over 20 C). This year it was cool and rainy (never getting above 10 C), but across the board times were faster. The winners were around 3 minutes faster than last year. The median times for men were 9 minutes faster. And there was a less slowdown between the first and second halves of the race, with 3 times more people running negative splits (faster 2nd halves). The only negative changes – less finishers and less Boston qualifiers (not sure why that is).
|Second Half Slowdown||7.7%||5.7%|
|Fastest – Male||2:24:09||2:21:08|
|Fastest – Female||2:40:34||2:37:00|
|Median Time – Male||4:10:28||4:01:38|
|Median Time – Female||4:29:45||4:26:29|
Here is the analysis I did last year: 2013 Results Analysis. If I have time I’ll do some more in depth analysis for the half marathon results.
