i’m running the NYC marathon soon and am wondering how folks have used their watches in world major marathons (i.e., highly dense, tall building obstruction).
i was planning on tracking from workouts, but also have strava.
i figure GPS will be unreliable, but is it worth it to try and manually lap each mile (only on workouts, not on strava), or basically just use it as a fancy stopwatch that can give some stats on HR and rough estimates of pace?
fwiw, i have a series 8, so don’t have a dedicated button to lap and would need to double tap.
any other tips?
DC Rainmaker did several GPS accuracy tests of different devices in different environments (including NYC center) and Apple Watch was reasonably good (worse than dual-band devices, but still decent enough).
