GlenT: I'm pretty sure a $100,000 track (or whatever they cost) will be more accurately measured than your $200 Forerunner is capable of measuring.

JanetT: That's what I keep telling myself.

Wanna trade?

JanetT: And I think the cost was $1.2 million or some such, including all the drainage and other improvements (moving the tennis courts, etc.).

bbrooke: Is there such a thing as a metric track (based on meters) and one based on statute units (miles)?

I have no idea, just wondering that would explain the discrepancy. (Only because I recently heard a reference to a runner doing a "metric mile", and I have no idea what that is...)

Also, 400 meters = 0.24854847689 mile. That's 0.00145152311 miles less than an exact quarter-mile, which equates to about 2.3 meters.

Mystery solved? :-)

RLShadow: A metric track would be a 400 m track. A statute track (I'm sure that's not the right term) would be 440 yards. They are very close in distance, as bbrooke points out. 440 yards = 402.3 meters. 400 meters = 437.4 yards.

But that doesn't explain Janet's observation with the FR -- it would explain it if the FR were saying it was at a quarter mile a little after she completed a lap.

My guess is that the track is correct and there is just some small error in how the FR senses it.

I believe the term "metric mile" refers to 1500 meters, which is one of the standard metric race distances. I could never figure out why they didn't make it 1600 meters, a nice even 4 laps around a metric track, rather than having to start the race a quarter of the way around the lap.

JanetT: Dick's right, about my FR reading a bit short.

Sporttracks always reports my distances longer than the FR does, but also longer than Glen's FR does, when he runs the same distance I do (i.e., a couple of races we did earlier this year). I'd be very interested in what his FR reports for the distance around, on the inside line, in lane 1. :-)

Ah, well, I suppose I should start reporting the lap distance instead of the FR distance for these intervals... Still, I love having the FR for the map it produces, especially places I've never been before.
