The question "where did I run" relates to tracking or identifying the route or location of a run. To find out where one ran, many people use running or fitness apps that track and map the route in real-time or allow route planning ahead of time. Some popular options include MapMyRun, Strava, Footpath, RunGo, and Google Maps with route planning features. These apps use GPS data to map the running route, show distance, elevation, and offer sharing capabilities. Additionally, online tools like Maps.ie, Plotaroute.com, MapPlanner.com, and Mappedometer.com let users draw or track routes on maps, measuring distances and elevations, helping runners to know precisely where they ran. Such tools are especially useful if one wants to plan running routes or retrospectively measure the run distance by mapping it. Therefore, to know specifically where one ran, it is essential to use a GPS-enabled tracking app or map the route after the fact on an online route mapping tool.
