However, there are various permutations of ellipsoids and formulas that can be used in geodetic calculations - which ones in particular are being used by an app or device is rarely, if ever, disclosed. Smashrun uses a WGS 84 reference ellipsoid in conjunction with Vincenty’s Formula to calculate the distance between two GPS points. There are two factors beyond our control when it comes to figuring out total distance and, essentially, why we can’t ever guarantee that we can match another app or device’s distance: (1) which representation of the globe they’re using to calculate distance between two points and (2) the formula that's being used to calculate that distance. Why is my total distance on Smashrun different from my total distance on Garmin?.If you encounter a pause related problem with a file you imported, please email and include the file so we can take a look at it! This is a pretty tough task, so we're constantly working hard to fine-tune our pause algorithm and will look at any GPX/TCX file where Smashrun incorrectly detects a pause. What Smashrun does, under these circumstances, is guess where the pause took place based on a combination of metrics such as changes in your speed, heart rate, cadence, pace variability, and long gaps between trackpoints, where applicable. Many apps completely disregard these reporting standards and only close a track or a track segment at the end of a run, regardless of whether or not you paused. Of course, apps and devices don't necessarily follow this convention all the time either.

Every app and GPS watch handles it differently.Ī TCX file has a series of trackpoints within tracks (not track segments!) A closed track signifies a pause unless it shows up at the end of a lap and, luckily, TCX files do indicate lap changes. There is no easy way to differentiate between a closed track segment that is a pause from one that is the end of a lap. Other times, it only closes track segments at the end of a lap. Sometimes, a GPX file closes a track segment to signify a pause. The best way to think about pauses is to understand how GPX and TCX files are structured.Ī GPX file has a series of trackpoints within track segments.
