Track Run test

I would have covered the distance and pace, now everybody knows you are crazy :-D

Running that distance on a 400m track needs a lot of mental strength and even more craziness. But nice track and nice pace!

thanks :-). first 50 laps were hard, up to 80 even harder and the last 25 ok-ish, although there was no fun anymore. i was planning about 2:50, but the guy who joined me said it's a bit too quick so we should ease up a bit (1:26 first one) and see how the second half goes - and obviously it didn't go as planned :D - one would simply lose motivation (at least in my case) - so i said under 3h is fine too. it's an interesting experience :D - but not going to try this again.

Beg your pardon, but may I ask you for track description file (one from RunningTrack folder on your watch)?

Looks like Garmin approximate track with two strait lines (defined by it length in cm) and two semi-ellipses (defined by two semi-axis measured in cm) placed around center point (defined by two semicircles) and rotated (degrees). But first, the model i built by this data gives me track few meters longer, and second, there another one field i can't understand, so I try to find more information to work with. FIT SDK is silent on this data structure at this moment.

Is there a way to "recalibrate" without deleting the calibration file?  I've run several times on a track using track mode, and I'm still not getting anything close to results I'm seeing from others.  Today, I was running a pre-programmed workout.  The watch nailed the first few laps, but then it "missed" one by about 75 yards, which threw off the rest of my workout. 

A stupid question - but since the track is not at all what could be expected of the track run activity (as you point out): you are running used the Track Run-app and not the normal Run app?

Yes, I was using the "Track Run" activity (combined with a workout - alternating 800 with 400 rest).

I checked my "RunningTrack" folder, and it was empty.  I went back to my local 400m track, ran 4+ laps in Lane 1 on the track run setting (after getting a GPS lock), then saved the run.  Then I did another 4+ laps using same process.  I'm still not getting a smooth track, and my "RunningTrack" folder is still empty.  All software up to date, including the most recent GPS update.

I feel like I'm missing something simple -- something to tell the watch "This is the calibration run."

Any suggestions (short of a factory reset - which I worry will mess up something else)?

Strange enough. There is no way to tell the watch to calibrate the track - it happens more or less automagically. In my last attempt at a new stadium, it takes only two laps to build a track profile - then all the laps were identical (945, fw5.50).

In the second photo I see a more or less adequate last lap - it seems that the watch has begun to understand something :) Maybe they need a little more distance?

In fact, I did try a little more distance yesterday -- another two laps.  Still nothing in my "RunningTrack" folder.  I chatted with Customer Support.  They had me send a copy of the folders on my watch.  Hopefully they'll have a fix.  In the meantime, I might try a different local track over the weekend, just as a test.  But I lived without track mode before, so I'll survive either way.
