It's not easy given the reason this is needed is to avoid GPS being the deciding factor as that hasn't worked well for most previously. 100, 200, 400 and 1500 don't need any special profiles. 800 definitely and 3000, 5000, 10000 if you start at the second further forward start mark would need a separate algorithm for the first lap to just snap to 400 at the finish line on the first lap.
Kieren Apr 2021 11:12am, 24 Apr 2021 4,168 posts	Kieren Thanks SPR. I've since watched a couple of YouTube reviews. I don't think it would work for me due to lane switching. My track can get quite busy and I think it's good etiquette to do fast work in lane 1, then move to the outside for jog recoveries. That's usually the widest lane but can be lane 3 or even 2 if others are using the track. This week we had courteous group of school children using sections of the track but keeping lane 1& 2 clear.

SPR Apr 2021 11:14am, 24 Apr 2021 34,011 posts	SPR Kieran - Do recovery distances matter? I also run my recoveries in outside lanes, I don't care whether it says 600 when I ran 610 as the workout portion is correct and that's the bit I want accurate data for.
SPR Apr 2021 11:17am, 24 Apr 2021 34,012 posts	SPR BTW, if you were really bothered. You can switch lanes on the watch mid workout.
Kieren Apr 2021 11:22am, 24 Apr 2021 4,169 posts	Kieren Recovery distances only matter for me as use the watch to decide when to go again. The plan I am following has distance based recovery rather than time. This is as solo track runner. I suppose on a properly marked track or running with a group/ club I'd be using the track markings so we set off at the same point.
SPR Apr 2021 11:26am, 24 Apr 2021 34,013 posts	SPR Yeah that's the way I see it on a track. If recoveries are 400m then it's based on lane 1 as you will always start your reps on a marker for distance based on lane 1.
SPR Apr 2021 11:31am, 24 Apr 2021 34,014 posts	SPR What's the story behind the 386 metre track? Was the measurer drunk at the time and nobody else picked it up? Lol.
Badger Apr 2021 11:41am, 24 Apr 2021 13,783 posts	Badger Yes, you'd definitely have a mode to tell it what was going on - though either way, it would work fairly cleanly if you could tell it that the first time you cross the main start line, it is 400m or 200m depending on the race distance, wouldn't it? Or does the pace it shows you live during that first lap depend on the lane it thinks you're in?
SPR Apr 2021 11:47am, 24 Apr 2021 34,017 posts	SPR Yes, that's it Badger my pace graphs look a lot better now given it is calibrated to a lane. If you can't use calibration markers then you won't have accurate pace info and that would be very useful for anyone that wanted to use it for pacing. 800 is short enough that you just have to commit anyway but the pacing info could be useful for some in the longer distances.
