What is "Consider Elevation in Calculating Speed?".

If you do not check this box, the track we spit out will be basically a flat line of speed. In other words, you will be going the speed you specify for the entire duration of the track. If there are hills, and you specify 20mph, you will be climbing the hills at 20mph. That is not very realistic. If you check this box, we will implement a special algorithm in calculating your speed. As the grade increases, the tool will slow down your speed on the track. As the grade heads downhill, your speed will be increased. Note that this algorithm is tailored for moderate, touring cycling. Run results may not be very accurate - especially trail runs.

What is "Convert a Route to a Track?".

Basically, the GPX file format allows for two types of files: Routes and Tracks. A route is a plan of somewhere you are about to go, and a track is record of an activity that you actually did. The Gmaps pedometer app (and apps like it) spit out a Route (not a track) for finding your way. Our tool is able to read this type of file, but by default, it returns a Route file if that is what you have uploaded. By checking this box, you can have our app translate your Route file to a Track File. This is a great feature because Strava does not accept Routes - only Tracks.

Time Shift.

If you check the Time Shift box and your GPX file has time stamps in it, we will set the very first point in your ride to the time stamp you supply in "Activity Start Time." We will then calculate the difference in time between the time you supplied and the time provided in the track. We will apply that time-shift to every point in the track. This way, the exact speed you traveled is maintained; the only difference is the time that you did it. If you select this option, "Desired Average Speed" and "Consider Elevation in Calculating Speed" will be ignored. The time zone you supply is important - if you supply the wrong time zone, your track may be time-shifted by more (or less) than you expect.
