The Marathon Hamburg App is the top tool for participants and visitors of the Haspa Marathon Hamburg:

Participants can view and share their position live via GPS during the race with the "Track My Race" function.

Spectators benefit from the following features, whether onsite or at home:

- Track My Favorites: participants can mark and follow their personal positions live during the race.
- Live ticker: by this button you can instantly call up the real-time commented race.
- The leaderboard lists all participants at the time measurement points as they pass through and provides projections of the expected finish time.
- Spectator information: Here you can find important information on the topics travel, hotspots along the route, route map and meeting points after the race.
- The Facebook, Instagram and Twitter buttons lead to the social media profiles of the Haspa Marathon Hamburg.
- The Social Wall collects all #HamburgMarathon posts by participants or viewers on event profiles on Facebook, Instagram or Twitter.

Longer use of the GPS receiver can drastically shorten battery life.
