Live Rank & GPS Timing

Provide your Leaderboard live online. Easy real-time Scoring, Ranking & Results based on GPS Tracking

Enable GPS timing with a shadowtrack.

Description of Racemap GPS Timing


  • Unique URL for each GPS result list:

  • Sortable List by each column

  • Auto Update: results and rank updated automatically every 10 sec

  • Track Download: cloud pictogram to download recorded GPX files of specific participants

  • Each device: GPS trackers same as our Tracking App - no additional timing hardware needed

  • Real-time Prediction of rank based on the average speed along the shadowtrack

  • Net Results: If GPS device passes a virtual split (geo fence) within 100 m distance from shadowtrack, time difference from 1st (normally "start") split is calculated

Access Racemap GPS Result List

There are two ways to access the GPS result list:

  • Click the clock pictogram in search bar of tracking map

  • Use the unique URL

Spectators access GPS results directly in search bar of the tracking map through the timing link.

The Clock Pictogram refers to the Live Rank of your Contest.

You also reach the result list through a unique URL.

Best Practice for GPS Timing

Prevent accidental Start and Finish reads

If participants wait before starting the race and their GPS device already sends locations within the "Start" geo fence, in that case GPS Timing might be triggered too early. The same szenario is possible with "Finish" detections in the finish area.

To prevent unintentional start- and finish detections just move the virtual split for "Start" 100 m along the shadowtrack (= 100 m behind real start area) and the "Finish" timekeeping 100 m against the shadowtrack (= 100 m before the real finish).

Ensure mapping from Start

For GPS timing and LiveRank the algorithm needs to be able to map the location of the real start area to the virtual "Start" on the shadowtrack. If the 1st location the algorithm receives from a device is closer to lap three then this device is mapped into lap 3 with the wrong distance on the shadowtrack.

shadowtrack too close to start area causes problems with mapping

Accuracy of GPS Timing

We made a comparison of GPS timing against a professional timing solution during the 100km-Duathlon:

The comparison of our GPS timing solution against a timing system shows

  • GPS timing provides results with low budget and low effort, no additional hardware needed

  • Same sequence of the scoring with GPS timing and with professional timing solution

  • Possible accuracy of 1 min, depending on tracking interval of GPS device

User Story Lap Counter

For an ionoca E-Car race of the ecoGrandPrix series splits were used

  • as a live lap counter, GPS Timing List

  • to measure the duration for charging the cars

  • to detect the finish.

There for we set-up a shadowtrack with 60 laps and a geofence @ charging zone_in and @ charging zone_out for each lap, which means this event was running with 120 virtual splits. All information were provided through a live page
