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?
Use it for elapsed time and HR.
Distance won’t be reliable due to GPS issues amongst the tall buildings and not running the tangents perfectly.
If you have a goal time in mind, print out a pace chart and carry it. You can compare your elapsed time to the pace chart when you run past various mile markers.
