Will running on a cruise ship’s track with my gps watch mess up the distance?
Hi, I am going on a cruise soon and was wondering if when I run on the track that is on the cruise, will the distance and pace results of my Garmin Forerunner 450 (gps running watch) be messed up because of the ship’s motion?


Although I don’t have such a watch, I’m quite sure the answer is yes. GPS determines the longitude and latitude and calculates distance, speed, etc from that. Your cruise ship should have a sign on the walking deck that states how far one lap is.
