Suunto Ambit3 Peak User Guide - 2.5

Exercising with sport modes

Use sport modes (see Sport modes) to record exercise logs and view various information during your exercise.

You can access the sport modes under Exercise menu by pressing Start Stop.

Using Suunto Smart Sensor

A Bluetooth® Smart compatible heart rate sensor, such as the Suunto Smart Sensor, can be used with your Suunto Ambit3 Peak to give you more detailed information about your exercise intensity.

While exercising, the heart rate sensor enables:

  • heart rate in real time
  • average heart rate in real time
  • heart rate in graph form
  • calories burned during exercise
  • guidance to exercise within defined heart rate limits
  • Peak Training Effect

And after exercise, the heart rate sensor provides:

  • total calories burned during exercise
  • average heart rate
  • peak heart rate
  • recovery time

If you use the Suunto Smart Sensor, you also have the added advantage of heart rate memory. The Suunto Smart Sensor memory function buffers data whenever the transmission to your Suunto Ambit3 Peak is interrupted.

This allows you to get accurate exercise intensity information in activities such as swimming where water blocks the transmission. It also means you can even leave your Suunto Ambit3 Peak behind after starting a recording. For more information, please refer to the Suunto Smart Sensor User Guide.

Without a heart rate sensor, your Suunto Ambit3 Peak provides calorie consumption and recovery time for running and cycling activities where speed is used to estimate intensity. However, we recommend using a heart rate sensor to get accurate intensity readings.

Refer to the user guide for Suunto Smart Sensor or other Bluetooth Smart compatible heart rate sensor for additional information.

Putting on Suunto Smart Sensor

To start using the Suunto Smart Sensor:

  1. Snap the sensor firmly into the strap connector.
  2. Adjust the strap length as needed.
  3. Moisten the strap electrode areas with water or electrode gel.
  4. Put the strap on so that it fits snugly and the Suunto logo is facing up.

The Smart Sensor turns on automatically when it detects a heart beat.


Wear the strap against your bare skin for best results.

Refer to the Suunto Smart Sensor User Guide for additional information and troubleshooting.


Dry skin under the belt electrodes, a loose belt, and synthetic shirt materials can cause abnormally high heart rate readings. Moisten the belt electrodes well and tighten the belt to avoid heart rate peaks. If you are otherwise concerned about your heart rate, please consult a doctor.

During exercise

Suunto Ambit3 Peak gives you a wealth of information during your exercise. The information varies depending on the sport mode you have selected (see Sport modes). You get even more information, if you use a heart rate belt and GPS during exercise.

Recording tracks

Depending on the sport mode you have selected, your Suunto Ambit3 Peak allows you to record various information during exercise.

If your sport mode has GPS enabled, Suunto Ambit3 Peak also records your track during your exercise. You can view the track in Suunto app as part of the recorded exercise.

Making laps

During your exercise, you can make laps either manually or automatically by setting the autolap interval in Movescount. When you are making laps automatically, Suunto Ambit3 Peak records the laps based on the distance you have specified in Movescount.

To make laps manually, press Back Lap during the exercise.

laps Ambit3

Suunto Ambit3 Peak shows you the following information:

  • top row: split time (duration from the start of the log)
  • middle row: lap number
  • bottom row: lap time

The exercise summary always shows at least one lap, your exercise from start to finish. The laps you have made during the exercise are shown as additional laps.

Navigating during exercise

If you want to run a route or to a point of interest (POI), you can select a sport mode, such as Run a Route, and begin navigating immediately.
