Fitbit Surge update delivers running alerts and improves battery life

During his time with the Fitbit Surge, our own Terrence O'Brien was quite pleased with the wearable's tracking abilities. Thanks to a software update, the device aims to get even better. Fitbit is giving Surge users running alerts that'll keep you informed of time and distance marks, helping with pacing and overall training goals. The company has also improved battery life, so you can go a bit longer between charges when keeping tabs on running, hiking, biking and more. There's also a new timer/stopwatch tool when workouts require carefully timed intervals. Even with the new features, the Surge is still a tough sell at $250, especially in a space that's crowded with GPS-packing entries from Garmin, TomTom and others.
