The Forerunner 955 offers a few small software modifications as well as extra functionality. Some of these, like additional activity profiles. Considered as a premium running watch by Garmin because of its additional features.

However, there are three key aspects that deserve special attention. These will undoubtedly be worth the additional expense for some people.

A training readiness metric, the suite of Garmin Golf capabilities, and enhanced maps and navigation tools are included in these three features. All the features are worth it.

Enhancements To Maps And Navigational Features

The Garmin 245 and the Garmin 55 both use breadcrumb navigation, as does the Garmin 255. It’s helpful and preferable. However, the Garmin Forerunner 955 provides a fully functional map. Along with points of interest, the map also shows marked roadways and trails.

You can get turn-by-turn directions if you’re following a scheduled path. Additionally, even if you didn’t prepare a route in advance, you can utilize the round trip course designer to create a route of any length.

Enhanced Performance Metrics And Training Readiness

This new metric is intended to inform you of your readiness for a demanding workout and your level of recovery. It accomplishes this by integrating a variety of different measures that are already offered by the Forerunner 255 and other watches, so it isn’t really unique. However, it’s convenient to have a single score that sums up everything on one screen.

Data on sleep, recovery time, heart rate variability, stress, and acute training load are used to determine training readiness. You might want to wait to work out the next day if any of these measures are out of sync.

The 955 also includes information on acclimatization to high altitudes and heat. It keeps track of your training in these scenarios and uses the data to enhance its algorithms for VO2 max and other performance metrics.

Real-time endurance is another relevant aspect. This statistic seeks to keep track of how much energy you have both before and throughout an activity.  It’s a cool feature that may be worth experimenting with.

Golf Features On Garmin

The availability of Garmin Golf is another truly special feature and enhancement on the Garmin 955. This is a terrific set of features to have on your watch if you play golf.

You can view information like the distance to the hole by loading data for the course you are currently playing. Although the 955 incorporates these functions with your running watch, there are Garmin devices designed exclusively for golfing.

This absolutely justifies the additional cost of the 955 if you play golf and run.
