After importing a workout from your GPS you may find that the distance doesn't match what you expected for the activity. Or you may find while viewing the route for a particular activity that it veers off in unexpected directions or there are long straight segments where you lost GPS reception. This is an unfortunate limitation of GPS technology which will require you to edit the GPS route. Fortunately this is quite easy in SportTracks.

Select the activity you want to edit in the Daily Activity view. If the map tools are not visible above the route, click the Wrench button in the route view title. Click the pointer tool button in the map tools area and select Edit to go into editing mode.To get a better view of the route, you may want to maximize the view. If you are calibrating the route to a street or trail which is visible in the satellite imagery for your area, you may want to select a map background. If you are having difficulty seeing the GPS route after selecting a map background, you may want to change the various options under Settings > Route for line color, width, and transparency.

Use the mouse to pan the route to the area you want to edit. To move the route, move the pointer to any area of the route window which doesn't have a route segment, click the mouse and drag the window. You can pan by dragging the mouse when you see the hand pointer (), which can be selected from the dropdown control on the tools bar.

Zoom into the route by clicking the zoom buttons   in the map tools or using the mouse wheel. You can re-center the route by clicking the Fit Route to Window button .

Once you have found the area you want to edit, move the pointer over a GPS point and the pointer will change to the Edit pointer (). To move the point, click and drag the GPS point. Notice that the info tip updates the point distance as you are dragging and when you release the mouse button the distance and pace in surrounding views (such as the activity list or activity detail) will be updated.

If you have a long GPS segment that is cutting off a corner, you may want to add additional GPS points to the route. To insert a new GPS point, move the pointer over a line until the add pointer appears (). Click the mouse and drag the new point to the desired location. The time of the new GPS point will be determined by the surrounding points and the distance along the segment.

To delete a point, click the point once and hit the Delete key on the keyboard. You may want to remove GPS points if they are too frequent as this will cause your pace charts to jump up and down a lot.

If you find the info tips are getting in your way, you can hide them by clicking the Show/hide info tips button in the map tools area.

Manually overriding activity time, distance or climb data

Normally the total time, distance, and ascend/descend of an activity is calculated based on the GPS data. However, sometimes you'll find that the GPS reception is so poor that it is unusable. Or, you may want to override the distance for a known, measured course such as a track where you would like the distances to be exact. In this situation you can manually enter time, distance, or ascend/descend values to override the GPS calculated data by clicking the button next to the distance entry in the activity detail view.

When you change from GPS calculation to manual entry, you may see the time and distance change. On GPS devices which support lap data (such as the Garmin Forerunner and Edge series) these entries are prefilled from the values imported from the GPS device. You can switch back and forth between manually entered and GPS calculated values at any time.

Why do the times and distances in SportTracks not match the values on my GPS device ?

Editing elevation data

If the ascend/descend numbers or elevation chart for the activity look off, you may want to edit the elevation chart. From the Daily Activity view, change to the Elevation page and maximize the elevation chart:

Select the Elevation data / Time chart:

When the Elevation data / Time chart is selected, each GPS point will be shown as a box on the elevation chart. To move a single point, click and drag the point up or down. To move a range of GPS points first select a range by clicking a point and dragging to the left or right. Release the mouse, click any point in the range, and drag up or down. If you need to adjust the range of selected elevation points, drag the vertical dashed line to the left or right. To remove any of the elevation data, select a single point or range of points, and click the Remove button. If the elevation data is so poor that it is unusable, start at the first GPS point, drag to then end, and click the Remove button.

When you remove elevation data, the actual GPS points (latitude, longitude and time) are not deleted; the elevation data is simply cleared out.

Editing heart-rate data

Editing heart-rate data is similar to editing elevation data. From the Daily Activity view: 1) Change to the Workout page, 2) Maximize the heart-rate chart and 3) Select the Heart rate data / Time chart. You can move heart-rate measurements up and down, remove or add new heart-rate points. To add heart-rate data, click the Add button and enter the time and BPM.

Splitting an activity

It is occasionally useful to split an activity. For example if you forgot to press Reset on the GPS device and accidentally merged two workouts into one track. The symptom of this will be seeing only one activity imported from the Import wizard which has an unreasonably large time or distance (such as 20 hours, 300 miles). You can cut an activity into two activities using the Edit activity > Split activity command. The Split Activity window allows you to specify an elapsed time or distance which will be used to split the activity. Below the time and distance selections, you will see a preview of time and distances of the two new activities after the split. To determine the split time you may want to use the route, view and click on the segment where the split should occur; the time and distance will display in the info tip.

It is important to note that the split function will remove the GPS segment where the split occurs. The GPS point immediately before the split point becomes the end of the first activity, and the GPS point immediately after the split point becomes the start of the first activity. This has the effect of removing the elapsed time and distance from the GPS track, which is usually what you want when an inadvertent "join" occurs.
