TrailRunner

TrailRunner is a fitness tracking and route planning app for macOS designed to help runners, cyclists and outdoor enthusiasts log their workouts, plan running and cycling routes on maps, and monitor their performance over time. The app integrates with GPS data, lets users track metrics like distance, pace, elevation gain and time, and helps build training logs for endurance sports. It appears to be aimed at individual athletes and casual fitness enthusiasts who want desktop-based workout planning and analysis.</description> <parameter name="recommendation">We could not find recent information about TrailRunner's development status or whether a native Apple Silicon build is available. The app currently runs under Rosetta 2 on M-series Macs, but Apple is removing Rosetta entirely in macOS 28 (September 2028), giving you roughly two years to establish a plan. Contact the developer directly through the app's documentation or support channels to ask whether they are planning a native Apple Silicon update. If they confirm no native build is in the works, consider migrating your workout logs and route data to a more actively maintained fitness app with confirmed Apple Silicon support, such as Strava, Apple Fitness+, or MapMyRun — all of which run natively on M-series Macs and sync with external devices and services. If you decide to stay with TrailRunner, bookmark the developer's site and check back periodically for updates as the September 2028 deadline approaches.
