Along with the battery life, this watch is built for long periods of trail running due to the 810h military standard materials that make it rugged and sturdy.  The touchscreen of the watch still functions appropriately in cold and wet conditions and is responsive enough even on gloved hands. 

However, the screen brightness is not enough on very sunny days and you might find the touchscreen unresponsive. Some users have also noted the screen lag from time to time. The tree-style menu of the watch helps runners navigate the apps and features easily. This product has a weather tracker that provides runners with accurate weather reading while on their runs, although this does not feature an NFC that supports virtual payments.

Reviewers have lauded the solid and accurate GPS tracking for the Suunto 9 Baro Titanium along with its navigation options such as pre-saved routes, a compass and POI that can be uploaded from a desktop.

How To Choose the Best Trail Running GPS Watch

The best trail running watch should be able to offer great performing features that would aid them in their running and get their money’s worth.

A combination of smartwatch and multisport features should be considered and studied upon by runners before purchasing. Let us lay down some key considerations to help runners choose the best trail running watch in the market:

Your Trail Running Goals and Preferences

Ultimately, what you want to accomplish will dictate what kind of features you need in your trail running watch. Are you looking to track your oxygen levels while trail running? Then consider getting something like the Garmin Enduro. Need something that is solar-powered? You’d be happy with the Fenix 6. 

Battery Life

As a trail runner, one of the worse things that can happen to you during your run is to have your watch die on you— especially if you’re in the midst of a competitive marathon. The Suunto Baro Titanium claims to last for 7 days on full-feature mode— which is the longest battery life from all of the list above.

Compatibility

Different running watches also have different compatibility with other gadgets. For example, Apple Watches are not allowed to connect to Android devices.

Some Garmin watches can easily connect with an iPhone, however, runners might not be able to use all the features of the Garmin watch if they do so. To maximize usage of features, it is best advised for runners to look out for the gadget compatibility of their running watches options.

Functions

Tracking runners’ performance depending on their trails would aid greatly in choosing a running watch. For beginners in trail running, they can opt to buy a running watch that offers core and basic functionalities such as accurate GPS and heart rate monitor such as the Garmin Forerunner 55.

On the other hand, experts or experienced trail runners might look for premium features such as water resistance and stride length measures like the Garmin Enduro.

Health-monitoring features

Trail runners looking to monitor and track their performance and recovery should consider purchasing a running watch that offers accurate tracking of heart recovery rate, VO2 levels and oxygen consumption. 

The VO2 level tracking would give runners insight into the amount of oxygen they use during their runs. On the other hand, the heart recovery rate will show runners how much their heart rate decreases after their runs.

Aesthetics

While this would be the last consideration, it is also an important factor to consider. After all, when you look good, you feel good. And when you feel good, you’ll be motivated to run faster, longer.

Frequently Asked Questions

What is a barometric altimeter?

Some trail runners consider tracking elevation as a vital part in their running routines since they mostly run on either hills or uneven terrains. A barometric altimeter can alert runners when there are changes in elevation, pressure and altitude. 

When a trail running watch has this feature, it can track elevation steadily and more accurately compared to a GPS. If your trail running watch cautions you regarding a change in the pressure of the atmosphere, this might mean there will be an incoming storm in your running area.

Do I need to monitor my blood oxygen while trail running?

Blood oxygen monitors or Pulse Oximetry are features that help runners know the level of oxygen their blood receives. Many running watches companies have claimed that their watches with these features are not intended for medical use, however, this could be helpful for the overall fitness of a runner or an athlete. 

As stated before, trail running sometimes requires you to run slower or yield more physical effort to surpass hills or uneven terrains. Areas with higher elevations have a lower concentration of oxygen. When there is a decrease in the oxygen level, your heart rate will increase, resulting in a running out of breath feeling.

Pulse Oximeters in trail running watches can alert runners when they are getting lower values and guide them into going back to the normal values.

What are the advantages of tracking my cadence?

Running cadence refers to the number of steps you take every minute. It has been said that the ideal running cadence should be between 150-200 steps per minute or SPM, which varies from runner to runner.

One great advantage of tracking your cadence is that it improves your running form. A fast step rate means you run lighter and faster which reduces your energy loss on the run. Aside from this, your running position is more efficient due to the fast cycling of your legs when running.
