Technical Information

Change your wristband to suit your style

Forerunner 935 is elegant, lightweight and comfortable - ideal for daily use.Forerunner 935 is compatible with our range of QuickFit™ easy-to-change wristbands. Our range includes wristbands for all occasions: you can change your sporty silicone band for a more elegant leather band or high-quality metal wristband.

Monitor your performance, training and recovery time.

Use Forerunner 935 to monitor your training and recovery times to help prepare for races or training sessions. Use training mode to monitor your performance and assess your track record and performance so you know if you are training effectively. You can also consult your overall training programme to measure the quantity of exercises over the last 7 days.

Analyse your technique

This device offers an easy way to use the data required to improve your fitness. You can even use Forerunner 935 to measure running metrics with Running Dynamics to analyse your performance.

Longer battery life

Train for longer with a reliable long-life battery, even for Ironman triathlons or ultra-marathons. Forerunner 935 has up to 24 hours of battery life in GPS mode and up to 60 hours in UltraTrac energy-saving mode. And if you wear it everyday like any other connected watch, it has two weeks of battery life before needing to be recharged again.

Running, swimming, cycling, triathlon

With Forerunner 935 you can easily change from one sport to another with pre-set running (indoor and outdoor), cycling (indoor an outdoor), swimming (pool/open water), cross-country skiing, rowing sports, trail running, hiking, body building, and more.

Listen to your heart

A wrist heart-rate monitor is very practical for running unhindered when racing, but the Forerunner 935 offers more data collections with a compatible heart-rate monitor strap. With a compatible heart-rate monitor strap (such as the Ski-run™ or Term-time™) you can use advanced functions such as lactate threshold and the stress test according to heart rate variations.

Personalise your device and connect

Forerunner 935 automatically connects to Margin Connect, the free on-line sports community where you can check your performance and even share your results on the social networks. Connect to Margin Connect on your desktop or download the Margin Connect™ Mobile application on to your compatible smart phone. Personalise your device by downloading free data fields and watch faces on Connect IQ™.

Push yourself further every day

Find the motivation you need to push yourself beyond your limits with Strava Live Segments. Strava Premium members can synchronise their running and cycling segments on their Forerunner 935 and receive live commentary during workouts. Receive alerts at the beginning and end of segments, display your rankings, and see where you are at compared with your personal records.
