<maths geek> Hmmmm, that site says that the percent figure is the percentile. If so, that would mean that, say, 65th percentile would put you in the top 35% of the population, or 50th percentile would put you exactly half way down the population. What the population is here isn't clear though. Presumably all the people of the same gender and age group that they have times for. It's a pretty meaningless statistic unless you know what the population is.

It's not the same thing as 65% of the best person's time/score/whatever - as it all depends on how the population is spread. So you might get 60% in an exam, but be in the 95th percentile, even though someone got 100%. Or you might get 95% in the exam, but only be in the 60th percentile, if it was a very easy exam and lots of people got 100% or close to it. </maths geek>

I hope that makes some kind of sense - it's so much easier to explain it with graphs

I had a feeling that might be the response.

Maybe this makes more sense:

If you're in the 65th percentile, you're better/faster/smarter/taller/shorter/geekier than 65 percent of the population. Whatever the population is...

Cheers!
It means that if you were a senior man (<40) rather than a vet, your 45.32 would be worth 31.35. The higher the percentage, the closer you are to the world record for your age group.
Taking my time (31.29) as a percentage of the senior mens world road record (27.00 I think), it would give me 85.71%. So our pb's are roughly the equivalent.

Do I need to get out more???

Thanks for that. We both need to get out more and train harder if we want to get nearer that 100% mark. It's interesting to work out our percentages over various distances. My highest percentage is for the marathon - 89.18% - so I suppose that was really my best distance.
Cheers!

Wallsend 10K.
Won in 29:22 by Colin Walker, who was an international steeplechase representative at the time.
I was runner-up.
Third was Mike McLeod who was/is an Olympic silver medalist over 10K.
I'm embarrassed to admit to being guilty of indulging in former glories I'm afraid.

Why shouldn't you indulge, this is the kind of thing that makes you puff your chest out with pride.

Hmm... Chest puffing. Not really comfortable with that sort of thing; unless it's as a result of a particularly strenuous hill climb during a run.
