How to Dotwatch

Using the GPS tracker map is a key part of following ultra-distance bike races online. The tool is at once both a simple and complex aid, providing a visual glimpse at the current standings, and a detailed history of each rider's race, depending on how you use it.

Here, we explain the basics.

Rider Dots


Each rider is represented by a 'dot' on the map, which displays either their race number, or their initials. Looking at the map as a whole, and panning around, can give you a sense of the general shape of the race; who's out front, how big the gaps are, and who's currently active (a translucent, faded 'dot' indicates the rider is stationary).


  • Hover over a rider to bring up their name and key stats, such as current speed and distance covered.
  • Click on the dot to bring up more information about the rider.
  • Click 'Zoom to Rider' to view their exact location.
  • Click 'xxxxx Full History' to view the rider's race progress in detail.

Locating Riders


To locate riders on the map, open the 'Riders' list by expanding the button in the top right of the map. From here, you can either use the search bar to find a specific rider, or scroll through the list.


  • Click the + icon, which will show the rider's location on the map with an info box.
  • Click 'Zoom to rider' to zoom to their exact location.
  • Click 'Full History' to view their progress in the race so far.

Leaderboard


Clicking on the 'Leaderboard' tab at the top of the map will display a list of riders in order of progress made. The leaderboard is based off of each rider's respective distance to the finish, which is a simple measurement for races with a set route. For races with no set route, such as the Transcontinental race, distance to the finish is measured as the crow flies.

Race Flow


Click on the 'Race Flow' tab to view a very useful graph, measuring rider progress over a certain period of time. The X-axis represents time, and the Y-axis distance. From these two measurements, we can see each rider's progress - represented by the lines on the graph - in relation to the progress of others. Zoom in to the graph to view in more detail.


  • Flat line = Rider stationary / asleep
  • Steep line = Fast pace
  • Lines crossing = Riders passing eachother
  • Smooth line = Steady pace
  • Erratic line = Lack of rhythm / probable fatigue
