GPX Toolkit, a private repair shop for running routes

Field notes

The editor accepts GPX, TCX, FIT, KML, and KMZ files and exposes map-based operations such as spike removal, trimming, point editing, merging, cropping, and route reversal. It includes device-oriented reduction targets—500 points for Garmin, 250 for Wahoo, and 1,000 for Coros/Suunto—and can export either a GPX track or route. The page also describes an opt-in terrain-elevation request limited to coordinates needing elevation.
