Best Triathlon Watch – Buyer’s Guide on how to choose the Best Multi-sport Watch

A triathlon watch is effectively a multi-sports watch.  Here are three athletic competitions, cycling, swimming and running. Multi-sport feature allows you to switch between different activities.

So you have decided to buy a triathlon watch but how do you decide which one? It will make it easier to categorise the sports and the important features to look regardless of the activity.  Be highly motivated by knowing your fitness data and to know how you are performing in your activity.

You can use multi-sport watches as a daily activity tracker. Therefore like fitness bands, multi-sport watches can count your steps, monitor sleep patterns and alert you if you have been idle.

Many multi-sport watches have not become “smart watches”. This means you can pair them with your smartphone to enable many tasks such as receive calls, texts, notifications etc.

Multi-sport watch activities

Swimming Features

The most important feature for swim triathlon is to make sure your watch is water proof. To check this you can take a look at the ATM rating. This tells you how waterproof the watch is. For example a rating of 5 or more is ideal for triathlon swimming. A rating of 5 atmospheres means that the watch can tolerate five times the sea level pressure without letting water in. With a 5 ATM or higher, you can be certain to rely on your triathlon watch.

Another feature you look out for is to ensure the watch tracks you whilst swimming. A good swimming triathlon watch will track your speed, stroke length and stroke per minute.

Cycling Features

You will want to establish if the triathlon watch has a cycling mode integrated. With this you can ensure rotations per minute, speed, time and distance are tracked.

Power meter is a feature to look out for. This is what is used for precise measurements in cycling. This feature does come at cost, however if you’re looking to advance in your triathlon, then this may be an apparent feature.

Running Features

Whilst running features are universal and you will find come with any smart watch, features to look out are to check if your watch counts steps, distance, pace, calories, elevation gain.

If you want to take it one step further you may find you can track metrics like cadence and ground contact time. Cadence tracks how many times your feet strike the ground per minute. Ground contact time tracks how long your foot stays on the ground once it hits.

These features assist you to become an efficient runner. Better efficiency in running means being able to run further and faster with less effort. A triathlon watch with extra running features like these can help you to become a more efficient runner.

Therefore you can have one device that works as your triathlon watch as well as daily activity tracker.

What are advanced metrics?

GPS watches can offer more thorough advanced metrics as explained below.

HR Max

This is the rhythm that the heart reaches during an intense sporting activity. At rest, the HR Max is about 40 to 80 beats per minute depending on the individual. HR Max is unique to every individual and depends on your genes and age.

Knowing your HR Max can dictate the ranges for all the other zones in heart rate training.

Heart Rate Zones

Running watches uses your HR Max to break down your heart rate zones or ‘sport zones’ into segments and make them easy to understand.

Heart Rate Zones are labelled differently by different devises. These can be:

  • Recovery training (60% of MHR)
  • Endurance base training (65-70% of MHR)
  • Aerobic capacity training (75-82% MHR)
  • Anaerobic threshold training (82-89% MHR)
  • Maximum aerobic training (89-94% of MHR).

Heart rate zones estimated gives you a better advantage at obtaining the workout effect you intend to achieve.

Cadence

Cadence or foot strike rate is the number of steps you take per minute. It’s a imperative stat for determining the efficiency of your running form. Quick  and short stride length result in less impact at the ankles, knees and hips. The low degree of impact may help reduce injury risk. Experts believe that a running cadence of 180 steps per minute is ideal for optimum running efficiency.

Stride Length

This is the length of how far you travel with each left and right step. High cadence, shorter the stride length.

Vertical Oscillation

Running efficiency measured through a sensor built in the heart rate chest strap. It shows the degree of bounce in your running. The lesser the bounce, the less energy is exerted going up/down. Therefore the more efficient the runner.

VO2 Max

This is the maximum volume of oxygen in millimeters you can consume per minute per kilogram of the body weight for efficient energy production. It is an important metric for runners because it can have an affect on running efficiency and therefore improve form and prevent injuries.

Higher VO2 max means the better the body can delivery oxygen to your help your muscles. Low VO2 Max represents poor fitness.

Ground Contact Time

This is the amount of time in milliseconds your foot maintains contact with the ground whilst running.

Lactate Threshold

This metric gives a clearer insight of your endurance performance capacity. It is precisely the level of effort or pace when your fatigue accelerates. According to Garmin, experienced runners should have a threshold of 90% of the maximum heart rate. Average runners below 90%.

Recovery Time

This useful metric measures the length of recovery period that your body takes. After an activity, recovery time reveals the number of hours before you will be back full capability of performing an activity again. Calculation is based on a unique digital model of your physiology.

Excess post-exercise oxygen consumption (EPOC)

This measure is the boost in metabolism (calories and fat burning) your body gets after a workout. Sometimes also know as afterburn. During any activity, we burn calories to fuel our muscles, however when we are done, we keep on burning than we do at rest. It’s depends to what our bodies need to recover from the hard work they’ve just done.
