Why are distances in Garmin Training Center and TrailRunner sometime different?
21/09/08 02:22
Problem: The ForeRunner device displays a distance for a workout. Garmin Training Center displays the same distance but TrailRunner displays a different distance.
Background: Your ForeRunner records geographical data points during the workout. At the same time your ForeRunner internally sums up the distance for the workout. It could sometimes happen that if you sum up the distances between each data points the result will be different to what the ForeRunner has summed up during the workout.
Reason: If you have intelligent recording enabled on your ForeRunner and the GPS signal quality isn't too good, the device will alter the recorded geographical course after it knows better. Problem is that at the same time the overall distance should also be adjusted, which is not the case.
Status: TrailRunner takes only the geographical information from the workout and takes this as the base. If your ForeRunner has internally stored a different distance, TrailRunner assumes this as an error in the ForeRunner device as it delivers contradictory information.

Does TrailRunner support the Polar XXX monitor?
15/09/08 22:53
Problem: TrailRunner is not able to directly import Polar Workout data from the monitor.
Solution: With the helper application TrackRecord you can download workouts for some SonicLink Polar devices but Infrared is not supported. If you can manage to download HRM files with e.g. a windows emulator and Polar software you can import the file into TrailRunner. But it requires that you have worn a foot-pod during the workout as TrailRunner relies on the distance information to display a workout chart and merge the workout data with the course of a route.

What's the resolution of the workout data graph?
10/08/08 10:20
Problem: When I view my workout data in other applications like garmin training center, the data points for heart-rate and speed are much more noisy detailed than in TrailRunner. Additionally the TrailRunner graph seems not to start at the left edge of the chart but appears to be indented. Furthernore a TrailRunner graph line sometimes is being drawn as a straight line without any intermediate data points, although there should be some.
Background: Other applications display the raw data of a device. This makes the graph unreadable. The philosophy of TrailRunner instead is to display the overall trend and development of your workout session.
Approach: TrailRunner has an auto split feature where the workout is being sliced into fixed distance intervals. For each interval the statistical median value is being calculated and one data point reflecting this value is then being used as a representative. As the location of the representative can be somewhere in-between the first interval, the graph might appear to be indented. Furthermore if representatives in adjacent intervals fall onto a straight line, only the edges representatives are being drawn and the connection line depicts the trend development.
Details: The auto split feature uses the following distance intervals. By the time of this writing it’s 250 m for workouts shorter than 10 km, then 500m up to 20 km, 1000 m up to 50 km and 10000 m from there on. A route with 42 km would then have 5 intervals.

Why is there a discrepancy between the diary workout values and the map?
24/09/07 23:47
Problem: When you import a route. you can merge the course into the map and add a diary entry. When you choose to merge the course into the map the course of the route will be aligned to existing tracks. This means that the route will be modified and some values like elevation data or the exact course might become different to the raw data from the GPS. The diary entry instead stores the raw data. If you later compare them, they might differ slightly.
Solution: Please keep in mind that workouts are meant to be stored in the diary and not in the map. The map is the base for planning future routes and by merging route courses into the map you complete your network of tracks more and more. In the long run, workout information like heart-rate and speed isn't of any interest in the map. But in the diary, it naturally is.
Tip: If for some reason you really want to archive workouts and routes in the map, then you should import the courses in one piece and select TrailRunner > Preferences > Advanced > Store workout data in the map. This will not alter the course of a recorded route (but also will not add crossings or remove redundant tracks) and will keep the workout data persistent in the map.
