Glossary: Recurring route
A recurring route is a route that you have completed several times. Runalyze compares all your routes with each other to find activities on one and the same route. These activities are then assigned to this recurring route.
How does the route matching work?
First, possible matches are determined for a new activity via the distance, the start/end coordinates and the minimum/maximum coordinates (i.e. south-western/north-easternmost point). A maximum difference of 200m or 4% for the distance is permitted. The routes are then compared with each other (via dynamic time warping) and evaluated. The resulting value must be below a certain limit for a match. The sequence plays a role in the comparison and differences are “penalized” quadratically. It is therefore not a problem to be on the other side of the road from time to time, but it is more of a problem to take a short detour.
