LIST YOUR 5k PR AND AVERAGE MILEAGE THAT SEASON

For Girls!

18:00 (split in 6k)

65 average during season(up weeks were low 70's, down weeks low 60's/high 50's)

75 consistent over the summer

5k pr: 15:37.02

Mileage that season: ~57.5

Good luck with whatever this is for.

15:56 ~70

Hey everyone, thanks for helping me out with this. I got tons of responses in just a couple days and have already assembled the data.

For the record, it was just one problem on a problem set and I'm three weeks into my first stat class ever, so it's not a super intense analysis or anything. As a lot of people said on the thread, there were a number of things that I didn't account for (nor did I intend to), such as age, talent, injuries, and even gender. I also did my best to remove things that seemed made up, but obviously I can't be sure sometimes so who knows quite how accurate the data is. That being said, it does illustrate that mileage has a measurable effect on times. Anyway, here's the short version of my results:

From what I collected, mileage and times had a correlation of r=-0.53 (if you don't know much about stat, r is a value between -1 and 1, so a short explanation is that -0.5 basically means that they're correlated, but only to an extent). Performing a linear regression on the data yielded the equation: Time (in seconds)= 1057.527-2.003(miles). So according to that model, every mile you run takes ~2 seconds off your 5k time. Obviously the model doesn't do a perfect job (especially at the extremes--according to this if you run 0 miles you would still be able to run a 17:37 which obviously is not the case for most people, if anyone) but the equation does have some merit and is based on the data I collected.

As for the more in depth analysis (with graphs and all), I sent it to letsrun, so if they want to do something with it, they can. If any of you are interested, though, I'd be happy to email you a copy (email me at

), and if more people post and I get some free time, I'd definitely add the new data and see if that changes things. Thanks again everyone!

hey, 17:38 5k on roads 35 mpw

Season before hand averaged 70 mpw.

The reason the high mileage guys disappear is mainly because during the actual season you don't run 100 + mile weeks. When you speak of higher mileage this is in reference to the base phase prior to and at the beginning of the season. After that, when speed training begins, the mileage per week is usually dropped anywhere from 50-90 miles. The point of the base phase is to provide the aerobic strength and conditioning to be able to get the most out of your speed phase of training and your races (while also getting added benefits later on). Also, if you're asking for their fastest time, which is at the peak of the season (no matter at what point of the season it was or was supposed to be), you're encouraging their brains to remember that period of time, in which they would have been doing even less mileage and this could sway them to reply to your question with a lower amount. I also don't know a ton of high mileage runners that keep of with their mileage per week religiously during the season.< This could simply be my ignorance or just folkways of running in the region in which I live.
