Riders and Checkpoints
Click on a rider icon to display the riders name, location and estimated distance along the course.
Rider icons are coloured by category (generally different ride lengths) and will have the riders initials.
Click on a checkpoint icon to display the
distance, location description and closing times. Clicking anywhere on the route will display approximate distance.
Click on the tab icon to open the tab. To close the tab click on the icon again (it will be highlighted
blue when the tab is open).
Filter Tracked Riders Tab
List of riders with tracking devices. Selecting a category will display only riders in that
category, such as Males, Females or a distance category when an event has riders participating in
multiple lengths. Clicking on a heading displays the list of riders and shows only the icons of the riders
in that category on the map. Clicking the All category will restore all riders icons.
Click on the rider's icon in the list and the icon on the map will bounce, making it easier to find.
Click on the rider's name in the list to display the rider's information on the map.
Ride Information Tab
Display basic information about the event such as name, distance, a description and the start and
end time of the ride in your local time. (All times are shown in the viewers timezone, not the event timezone)
unless otherwise noted. This tab also has links to twitter and a checkpoint times spreadsheet (if available).
List all Riders Tab
Displays a list of all riders in the event, sorted by surname and firstname, regardless off if a tracker
is being carried or not. Where a tracking device is being carried a link to the trackers website is
By default the page will auto-refresh every 5 minutes. It will update the locations of riders icons only, it
doesn't reload all the data so has low data usage for mobile broadband users. Unclick to disable auto-refresh.
Refresh Positions Button
Checks the position of riders and moves icons to new locations if new GPS data is available. It is
much preferable to refresh using this button rather than the browser refresh. This button only gets location
data so uses much less data and is much faster than doing a full browser refresh. Using the refresh button
in the application also allows the application to give more accurate speed and location data.
Times / Distance
Click on a rider icon to display location and estimated distance along the route. The distance is
an estimate. It's calculated using this algorithm: find the closest point along the route to the
report GPS position. Check if this seems reasonable:
If the rider has a valid previous position check if it would be feasible to be at the
new position based on the previous location and time.
If the rider does not have a valid previous position then use the time and distance
using some preset min/max disances to narrow the search.
The estimate is based on the closest route position to the reported GPS position. This may cause
problems on routes which go over the same road, such as out and back rides, but it does use time
and previous known location to attempt to sanity check.
