Nice workout! You really trust the garmin that much - isn't it a 400 m track?
Uss. measured 20" in from inside radius...
I finally saw the planets I think you were talking about...one really, really bright, next one not so bright and third in a row pretty faint - does that sound like them?
Thanks. No, I don't trust the garmin THAT much. At best, for civilian use, I think it's + or minus 30 feet on any given reading. I just find it curious that the distance is consistently long. It is a 400 m track, I believe. It's fairly new and 400m is the standard, right?
Yep, those are the planets. Venus = brightest, Jupiter next, Mars, then Mercury. Mercury is on the same line about 10 -15 degrees above the horizon. I think it was no longer visible by 6:30.
Now that I think about it, Mercury might be a bit brighter than Mars....??? Not that it matters but I'll have to check that tomorrow.
Glad to hear you're feeling better!
20cm from the inside, not 20". If there is a rail or raised curb, the measurement is 30cm from the outside edge of the rail. Unlike road measurements which need to be at least 100.1% distance to be certified, tracks are measured exactly. So, if you are super good at placing your feet and are leaning in on the turns, you could actually run as little as 399m per lap.
Garmins really don't like turns very much. On a relatively straight course, they are very accurate, but there's some sort of curve smoothing that goes on when you turn and it doesn't work out right. The readings are consistent, but not accurate.
There is a concrete 'curb' but its not raised. I'm guessing the measurement would be from the outside edge of that concrete. The gps tracks definitely go a bit wonky on the turns. Some of them are fairly well off the track surface, relative to the rest.
