Is The RunningLane Course 5K? Or Is It Short?

I have been to the Hunt course four times. I have been to Detweiller more than 100 times.

So ….. how long is each course?

There are two things I’m trying to accomplish here. The first is that I want to find out how long these courses are so that historic runs have an accurate course length attached to them. The second is to show people how to approach the issue of course measuring logically so that it is done right. The key to that discipline is to never mistake your “beliefs” for “knowledge”. There’s way too much of that going on here.

2.98 and 3.09.

How do you know that?

Not bad on Detweiller. It was measured 2.9758 with a tape.

Those are the average of our GPS readings from races and warmup. I realize they are not official but they are accurate.

How do you know they are accurate? Without me telling you the tape measurement. How would you know? Did you calibrate the GPS on a track?

Have run certified road courses. I know you don't trust GPS but they 99.9% accurate on road courses.

Did you use a single GPS result for the road courses, or an average of many measurements. It doesn’t matter what I trust. My mind is open to GPS measurements , but so far no one has presented evidence that they are accurate enough or precise enough to get close to the actual measurement. You just did. I don’t think we could ever say that the GPS would be good enough to certify a “national record”, but your method, if it holds, would be “pretty damn close”.

You are doing something others are not doing with their GPS units. Can you describe in detail what your procedure is? Do you notice a difference in average measurements when warming up versus race pace? Are you using the same GPS unit or many different types? Do you change the sampling rate? What is the usual spread of measurements? Are you always at 99.9 of a certified road course, or just most of the time?

There are a lot more questions but your methodology is worth investigating further.

Took me a minute but I found where I said the same thing way back on page 42

Saying you “are confident” isn’t the same as presenting data. Do you also get within 0.1% on road races with your GPS? I am assuming you dont measure 10 times and take the average.

Did you measure the Hunt course?

Even though the Newbury Park boys went 7:57-8:01-3:58 at the recent outing, I STILL think RunningLane was short because it was!

So what? NP boys are going to rewrite every track record this year and next year. Then you will blame shoes and pacing.

Guess where the 2022 NCAA D1 South Regional will now be?

Well they don't provide how the course was measured so it doesn't count.

I didn't read any of these previous posts, but just because they ran fast on the track doesn't mean runninglane was accurate. What a weird way to make that decision.

There have been a handful of athletes as fast as these kids who did not run that fast in xc.

Sort of. Three of these kids are juniors who are only 1/2 way through their track career. Give them 2 more seasons and there will be no track records left.

You need to read the thread to understand. People were saying it was short BECUASE they ran fast. Some were saying "wait until track season and that will prove it's short..."
