Just recording this in case Garmin and/or Strava might want to have a test.
- Watch (Forerunner 630) started 0700 Greece time on 29th September
- GPS in Ultratrac mode
- Spartathlon course run in 34:56 but watch not stopped until 23 mins after finish (~18:19 Greece time on 30th September)
- Watch was charged using a mobile USB charger at around 20 hours. Definitely not turned off or stopped/paused during the race. Finished with good battery life.
Garmin Ultratrac goes long by around 26kms (understandable due to the sampling but worth noting):
On upload to Strava, I get a course record time of 16hrs 18mins:
Trying to edit the run to correct things. The time and distance are actually uneditable:
But, pressing "Save" seems to smooth things out a bit, the elapsed time and the splits get closer to what I would expect. Seems like the "Moving Time" is determined to stick at 16hrs 18mins though.
I have the Garmin ".FIT" file and a GPX generated by Strava if you're interested Garmin/Strava... seems to be no way to attach them here.
