Description: Elevation is the absolute difference between the highest summit and the lowest valley. It may also be named altitude difference or altitude range.
Ascent is being displayed as ascent/descent value which is the gain in only positive / negative altitude differences.
Example: With an altitude series of 10, 13, 15, 13, 11, 16
the elevation is 10..16 = 6
the ascent is 10..15 + 11..16 = 10
and the descent is 15..11 = 4
Tip: As most GPS receivers tend to be very inaccurate with the recoding of altitude data, the ascent and decent values can become unnaturally high as only small gains can sum up to huge values. In TrailRunner > Preferences > Advanced you can set a high pass filter for the ascent/descent calculation. See Filter altitude noise.
Additional note: It may even happen that you record a round-trip and the ascent and descent values differ. This comes from the simple fact that altitude recordings made by a GPS are extremely inaccurate. To calculate the altitude, the GPS requires good reception of at least three satellites. If reception differs during two visits of a location, the derived ascent and descent values will also differ.
Solution: TrailRunner supports Dropbox. You can put the TrailRunner documents into your Dropbox and the data gets synchronized between all linked computers.
As you might already know, TrailRunner stores all vital information within your home directories Application Support folder
To move your TrailRunner data to Dropbox, follow these steps:
- Download and install Dropbox.
- By default, Dropbox creates a new folder in your home directory called
- Open this folder and make sure that a folder named
Documentsexists within. If this is not the case, create one with the exact spelling.
- Now go to:
- Within, find the folder named
TrailRunnerand move this into the aforementioned
Next time you start up TrailRunner, the application will check on if your home directory contains the following folder:
If that's the case, TrailRunner will access this location instead of the default
If the default folder does not suit you, these alternatives are also looked into:
As this folder now is located within your dropbox, it is automatically being backed up and synchronized between all computers being linked to your dropbox.

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.

Any other Polar HRM file containing distance information can also be imported into TrailRunner. This includes files with the .hrm extension or .xml extension that may come from polarpersonaltrainer.com
If you own a Polar S625x with Irda the only known way is to use a PC emulation with Polar Personal Trainer and then export a HRM file. Please let me know if you find any better solution. (Forum: MAC with polar watches)
Upload you data to polarpersonaltrainer.com, export as an Polar HRM XML file and import that into TrailRunner
Please let me know if you find any better solution.
Global Trainer GPS
Use the Timex Device Agent which works exclusively with TrainingPeaks. Export a PWX file and import the file into TrailRunner.
Supported GPS Devices
MacTravelRecorder can export GPX files from GPS mouses like the iBlue.
Supported File formats
TrailRunner can directly read and import files in the following formats:
GPX (either containing routes or tracks)
TCX (Garmin XML Database)
FIT (Garmin Fitness Database)
HRM (Polar HRM files)
XML (polarpersonaltrainer.com XML export)
fitlog (SportTracks FitnessLogbook)
If you have any different file format, use GPSBabel to convert it to any of the supported file formats above
Solution: TrailRunner supports the following OSM Render Styles: Classic OpenStreetMap, OpenCycleMap and CloudMade Fine line. To switch between these, Goto to Bottom Toolbar > Background Map > Display Settings. In the left pane select any of the available OSM tile servers.
Tip: As tiles are heavily cached in TrailRunner, you may want to right click the map and reload background maps whenever you see outdated tiles being displayed from the cache. To reload all osm map tiles, delete the following folder: < yourhome >/Library/Caches/TrailRunner/MapViewTiles/openstreetmap.org
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".
