I Tried a Garmin Watch with a Virtual Ski Simulator: Here's What Happened.

Winter brings not only darker and colder nights but also ski season, a time when resorts open their doors and ski lifts begin to operate. Many take advantage of this time to prepare their gear and head to the mountains. Whether they are experienced skiers or those who ski only once a year, documenting their sessions is both entertaining and informative. On this occasion, I had the chance to ski using Carv, an AI-based ski coach, while recording my activities with my Garmin to compare the provided data and its utility.

Garmin and Carv present two distinct approaches to performance tracking while skiing. Garmin devices, such as the Fenix 8, are designed to offer comprehensive tracking of various sports activities and focus on user well-being. In contrast, Carv concentrates on analyzing skiing performance through advanced metrics and real-time feedback.

Using the Garmin Fenix 8, one of Garmin's premium devices, one can observe the metrics it gathers, which are similar to those of more affordable models like the Forerunner or Instinct, which also offer tracking for snow sports. Heart rate measurement is fundamental in these devices, as it allows for evaluating physical effort across different zones. Additionally, it features GPS to record speed and location, which is essential for skiing.

When starting the ski tracking on the Garmin, it uses GPS data to identify the resort and knows which ski lift the user is on. It records distance, descent, and average and maximum speeds, breaking down the information by run. The Auto Run feature, which requires a barometric altimeter, facilitates the automated detection of each run.

Garmin's goal is to provide data about the ski session as a workout. This includes information about heart rate and time in various zones, which feeds into assessments of post-ski recovery time. For example, a day of skiing may recommend up to 65 hours of recovery based on the effort exerted.

On the other hand, Carv uses two sensor units that are attached to the ski boots and connect to a phone to gather data. Unlike Garmin, Carv does not measure biometric data; instead, it focuses on the movement of the boots to determine how the skis are performing. It collects information about edge angles, ski parallelism, and the skier's weight distribution.

Using Carv is managed through a mobile app, where all data is recorded once the activity begins. This tool analyzes each turn made by the skier, providing detailed information on edge angles and balance. Users can receive real-time feedback through their headphones, helping them improve their technique on the go.

While Garmin focuses on overall fitness, Carv aims to optimize technique on the slopes by delivering instructional videos and tips to enhance ski style, assigning a score known as Ski IQ. However, Carv does not offer heart rate data, which can be an important factor for some skiers.

When comparing the results from both applications, there were matches in some metrics, such as maximum speed, which was similar on both platforms. However, distance and descent showed discrepancies, suggesting that users should be cautious when comparing results between devices.

Both systems have their own advantages and purposes; Garmin focuses more on overall well-being and physical performance, while Carv is dedicated exclusively to those looking to perfect their skiing technique.
