Frequently Asked Questions
Is the Garmin Forerunner 70 a good watch for marathon training?
Yes. The Forerunner 70 includes Garmin Coach adaptive plans for 5K, 10K, half marathon and full marathon that adjust daily, plus Daily Suggested Workouts, PacePro pacing strategies, Race Predictor, Training Readiness and Training Status. Wrist-based Running Power and Running Dynamics work without external sensors, and GPS-only GNSS mode runs up to 23 hours, long enough to record a full marathon and more.
What is the difference between the Garmin Forerunner 70 and the Forerunner 170?
Garmin announced the Forerunner 70 and Forerunner 170 together, with availability starting May 15, 2026. The Forerunner 70 is the entry-level model: a 1.2-inch AMOLED touchscreen with a 5-button layout, 43 mm case, 40 g weight, up to 13 days in smartwatch mode and 5 ATM water rating. For a feature-by-feature comparison with the 170, call or chat with our team.
Can I swim or dive with the Forerunner 70?
The Forerunner 70 is rated 5 ATM, meaning it withstands pressure equivalent to a depth of 50 m, so it is safe for showers and pool swimming, and pool swim is one of its 80+ sports apps. It does not have an open water swim profile and it is not a dive computer, so do not use it for scuba diving or freediving.
How long does the Forerunner 70 battery last in each mode?
Garmin rates the built-in rechargeable lithium-ion battery at up to 13 days in smartwatch mode, up to 28 days in battery saver watch mode, up to 23 hours in GPS-only GNSS mode and up to 16 hours in all-systems GNSS mode. Charge the watch between 0º and 45ºC (32º to 113ºF) using the included charging cable.
