How does timing work?

Your smart phone, smart watch, fitness watch or activity tracker is your personal “virtual timing chip”. Start the session and run your marathon. When you reach 26.2 miles (42.2 km) stop the session and after, simply, link your Strava, Garmin, Polar or Suunto account to your runner profile. We also support session file import for GPX, TCX and FIT formats – so if you use other platforms nothing is holding you back from joining the party!
