What a great day to step into the community, welcome @Postmanpat57. With Fitbit Surge you can track several types of runs and exercises and use on-device GPS. Using the feature Multi Sport, you can map your walk, runs and hikes. 
To use your Surge during a run or other exercise (with a map):
- Press the Home button and then swipe to the Run or Exercise screens. To change your Exercise menu to see only the exercises you use.
- Press the Select button (lower right) or tap the screen, then swipe to find the type of run or exercise you want to track. You'll know whether the activity uses GPS if you see a GPS icon next to the heart rate icon.
- When you find what you're looking for, press the Select button (lower right) or tap the screen to start your activity.
- (GPS Only) If your run or non-bike exercise uses GPS, Surge will search for a GPS signal and vibrate when it is found. If a signal isn't found within a few seconds, a Quick Start option appears so you can start your activity immediately while Surge keeps looking for the signal.
- Receive time or distance-based updates (splits) on your Surge during a run. In the Fitbit mobile app: tap Account > Surge > Exercise Shortcuts > Run (on Windows 10 mobile devices, tap Free Run). Turn on run cues and choose your interval.
- Press the Select button (lower right) when you're done with your workout, then press the Action button to see a summary.
- Press the Action button (top right) once more to exit completely and return to the clock.
After Surge syncs your new data to the dashboard, you can see your workout details and assess their impact on your daily and weekly totals.
Hope this helps!
