How can I export my network of tracks

Problem: your network of tracks may have gotten very huge or contains some corrupted items you can't identify. Therefore you may want to start anew or make some kind of backup.
Solution: in network tracks mode, select a range of objects and Edit > Copy these. The clipboard now contains GPX fragments of these items. You can paste that into a second TrailRunner document or into any text file.
Tip: you can also use this technique to give parts of your network of tracks to a friend for that he/she can import these segments.

How can I reset hidden activities from the import

Problem: I accidentally clicked on hide activity while I was about to import it. Now the activity does no show up any more. How can I reset the list of hidden activities?
Solution: In TrailRunner Preferences > Advanced > Import : click on the Reset button.

The elevation data download looks to be very inaccurate

Problem: When TrailRunner downloads elevation data from the internet service, the elevation data looks inaccurate and does not match the GPS or odometer recordings of my GPS device
Description: TrailRunner downloads elevation data from a source that originally retrieved the data from NASA satellite measurements. What NASA did was to scan the surface of the earth and to record the topmost spot found during the recording. This could be the street level surface, a mountain peak or -- and that's probably what you are facing -- the top of a house or tree.
Solution: The error described comes from false GPS recordings. If your recorded GPS point is slightly off track due to a measurement error of your GPS, then the wrong elevation data point is being downloaded. Unfortunately there is no solution to this problem. Just ignore the spots where this had happened or correct the values by hand.
Hint: To correct values by hand, open the black info panel and manually enter elevation data value for spots that seem to be inaccurate.

Modify workout courses

Problem: You forgot to turn off your GPS device or the signal was very weak at the beginning of your workout. You would like to trim your recorded workout data at the beginning and/or end.
Background: You can only modify workout courses for activities while you are about to import them. Once they are within the diary, it's not possible anymore to alter them.
Solution: Use the track-point inspector panel to modify the activities track before you import the activity.
There are two techniques you can now use to correct the data to be imported before you actually import them. In both cases, first open the track-point inspector panel in the bottom toolbar:
1) Select the range you want to remove. In the track-point inspector panel select the 'trim selection' command. This will remove all data points from the selection up to the nearest edge.
2) Select one data point, e.g. the first datapoint of the presumable next workout. In the track-point inspector panel, select the 'split at selection' command. This will remove the selected data point and create two new entries for either side of the selection.

TrailRunner and Suunto compatibility

Problem: You have a Suunto fitness device and you want to display the recorded data in TrailRunner
Background: The Suunto applications Trek Manager and Track Exporter are only compatible with Windows.
Solution: Suunto offers a Webservice called Movescount that is compatible with Mac OS X.

Append workouts into one

Problem: You made several activity recordings and want to append each single activity to one concatenated representation.
Background: You can only append activities to each other while you are about to import them. Once they are within the diary, it's not possible anymore to alter them.
Solution: In the import pane, place a checkmark on each entry you want to concatenate. In the lower toolbar, use the Append toolbar button to replace both by a concatenated representation. Each activity will be represented as a lap within the resulting placeholder activity.

Make Route from Activity takes veeeery long

Problem: You have selected an activity and click on the make route button. TrailRunner becomes unresponsive and calculates for a very long time until the process is finished or seemingly never finishes.
Background: If you have already collected a network of track and merge new elements into it, the calculation of what is already there and what is similar and can be consolidated can be very time intensive.
Suggestion: Please read the quick-guide tutorial and understand what way-point perimeters mean. If you can set up your network of tracks to contain landmarks with good perimeters, the operation above will be much faster.
Workaround: The only alternative is to merge the track by hand (yellow sign) and then later recreate a route based on the spitted and joined tracks. This will also give you the opportunity to initially set up your way-point perimeters.

Activity workout splits and caclulated aggregates

Problem: When you drag the slider in the horizontal interval settings, the value for maximum speed changes. Why is that so?
Explanation: TrailRunner can display the maximum speed value from either the imported workout data (if available) or can calculate the value by an analysis of your workout data.

On statistical aggregates
If your GPS Device has lost its signal and re-catches it, the recoded course may contain errors. This error may lead to unrealistic values as such signal jumps may assume you where moving faster that light. Therefore TrailRunner uses a low-pass filter of roughly 90% and takes the highest value within the result as your maximum speed. To turn this off, uncheck the calculate statistical aggregates option.

On split intervals

The horizontal interval size slider controls the size of interval splits.
The intervals are being displayed as white lines in the graph, each containing a white circle on the value that was most common within this interval.
In addition the lowest values and the highest values within this interval are being displayed as a dot bordered gray region.
The overall maximum speed of an activity is the maximum speed from all these split intervals.
As this is a statistical calculation, the values may vary when you change the size of the split intervals. The bigger the intervals, any filtering becomes stronger.

Importing GPX files as Activities, Routes and Tracks.

Problem: When you import a GPX file, the following intentions may be on your mind:
a) The GPX file you import is actually a recorded workout of your own (possibly containing heart-rate data), so it's an activity.
b) The file contains a route created by someone else and you want to add it to your own list of routes.
c) You are interested in the tracks and way-points contained in the file and you want to merge them into your network of tracks -- to be used in future routes you create.

Solution: when you import a GPX file, TrailRunner asks you if the file is to be imported as an activity or a route. Chose either option.
When you want to import the waypoints only, go to the Document Toolbar > Locations and import the file there.

Tip: For a better conceptual understanding of TrailRunner and the difference between tracks, routes and activities, take a look at the TrailRunner QuickGuide Tutorial

Supported Fitness Devices, GPS receivers and file formats

TrailRunner directly and indirectly supports several workout recording devices. As it’s very time consuming to directly support fitness devices, I decided to interface with dedicated helper applications that do a much better job than I could do on my own. Go to TrailRunner > Preferences > Synchronize > Helper Applications to set the desired interface as described below.

Apple Nike+ iPod Sport Kit, Nike+ SportBand, Nike+GPS for iPhone.
Direct import of workout data when you attach your iPod as a volume, set the mount as volume option in iTunes. For the Nike+ SportBand and Nike+GPS iPhone app, in preferences set synchronization to, then in the main window click on Apple+Nike toolbar icon. Follow the screen instructions in TrailRunner to import your workouts from your account.

iPhone GPS Recording Apps
Most iPhone GPS recording apps are capable of sending a recorded session to your mac via email. If the file format is anything like GPX, KML or TCX then you can directly import the recording via drag and drop of the file onto the TrailRunner application Icon.
Some Applications like Trails, RaceBunny or iTrail use the TrailRunner native communication interface via wifi.

If you have any different file format, use GPSBabel to convert it to any of the supported file formats above

Can I merge GPS data with workout data?

Problem: Is there an easy way to merge GPS data and HR data into TrailRunner?
Solution: When your heart-rate data contains distance information, the you can do the following:
- First import the track from your GPS device, iphone or file and make a route of it so that it appears in the routes list.
- Remove the activity as otherwise you cannot add a new activity for the same date. - Then import your workout from your ForeRunner 50 or HRM file and select the route in the import panel.
TrailRunner will now merge the Heat-rate data and the GPS Data based on the distance information.
Note: For not GPS enabled workout devices you require a food-pod while your where running as TrailRunner requires distance information for the matching.

Diary: Display speed over distance instead of pace over distance

Problem: Is it possible to display the average speed in km/h or mph instead of pace?
Solution: An activity is always assigned to a diary. And a diary can be of a sport type like running, biking, etc.
If you change your default diary to the sport type biking, it would affect the display for all entries within this diary.

TrailRunner > Preferences > Personal > Diaries: Select the diary and then change the type in the table Popup.

TrailRunner is cutting of graph edges

: As depicted in the screenshot above, TrailRunner sometimes cuts off high values within a chart.
Background: To analyze a workout, the most interesting part of the chart is the area your workout did spend the most time in. If your GPS signal was weak and produced a noise peak, this single error would decrease the vertical resolution of your graph and therefore would make it unreadable. For this reason TrailRunner cuts off the chart for everything that is located outside of approximately 90% of your data points.
Customizing: To customize this behavior, you can control the display range under TrailRunner > Preferences > Advanced > Chart : Vertical exaggeration.

As depicted in the second screenshot above, the head or tail of a chart may not be displayed.
Background: The chart above displays a statistical trend. This means that TrailRunner takes all data points available, creates a set of intervals (in this case one month per each interval) and then displays a representative data point for this interval. The representative is the value that had the highest statistical appearance within the interval (mathematically this is called a median, not average). Then a data point is being displayed at the location of the representative. As this is almost never at the beginning or the end of the interval the graph seems to be cut off.
Sidenote: Please also note the gray border around the graph lines. The border depicts the maximum and the minimum values within each interval. So the graph gives you a good overall picture on the trend including extreme values. All data points are located within the gray area and the most frequent values are depicted by the colored line.

Does TrailRunner support the Polar XXX monitor?

Problem: TrailRunner is not able to directly import Polar Workout data from the monitor.
Solutions: Using third party helper applications, TrailRunner may read data files created by these application. Known solutions are:
- With 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.
- Any other application that can export GPX and TCX files from Polar devices can be used too, as TrailRunner can import these file formats.

Garmin Training Center shows a different distance as TrailRunner does

Problem: Your ForeRunner device displays a distance for a workout. Garmin Training Center displays the same distance but TrailRunner displays a different distance.
Background: During the workout, your ForeRunner records geographical data points. At the same time your ForeRunner internally adds up the distances as a total distance so far. 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 -- and therefore the derived distance -- after it knows better. Problem is that at the same time the overall distance should also be adjusted, which is not the case.
Status: To avoid confusion, TrailRunner usually displays the distance your device is displaying. But it could happen that the real distance, based on the mere data points, "slips through" in TrailRunner. This indeed is contradictory information but at the same time it is like impossible to me to "do it right".
