How to choose
- Heart rate accuracy. Hyrox mixes steady-state running with high-intensity stations. A tracker with a reliable optical sensor (like Garmin's Elevate or Polar's Precision Prime) that can handle rapid changes is essential. Look for reviews praising HR accuracy during HIIT.
- GPS precision. Running segments in Hyrox require accurate distance tracking. Multi-band GPS (like Garmin's or Suunto's) locks quickly and provides reliable pace data, especially in environments with tall buildings or trees.
- Battery life. A full Hyrox event can last 1-2 hours, but training days may be longer. Choose a tracker with at least 7 days smartwatch and 20+ hours GPS to avoid mid-session shutdowns.
- Comfort and weight. You will wear the tracker for long periods and during intense movements like burpees and rope climbs. A lightweight design (under 50g) with a soft silicone band reduces chafing and distraction.
- Display visibility. During an outdoor Hyrox race, you need a display you can read in direct sunlight. MIP (memory-in-pixel) screens like those on Garmin and Polar are excellent for daylight; AMOLED is brighter but may glare less.
Frequently asked questions
Can I use a fitness tracker for Hyrox without a phone?
Yes, many trackers like the Garmin Forerunner 255, Polar Pacer, and Coros Pace 3 store and display workout data without a phone. Syncing later with your app will upload the details.
Do I need a chest strap for accurate heart rate in Hyrox?
Modern wrist-based sensors have improved greatly. For most Hyrox athletes, an optical sensor like those on the Garmin Forerunner 255 or Polar Pacer provides sufficient accuracy. However, for perfect interval data, a chest strap remains the gold standard.
How important is GPS accuracy for Hyrox?
GPS is critical for the 1km running repeats. A tracker with multi-band GPS (like the Garmin Forerunner 255) will give the most accurate distance and pace, which is vital for pacing and post-race analysis.
Can I use a fitness tracker for Hyrox with a smartwatch like Apple Watch?
Yes, the Apple Watch Series 9 works well, but its battery life may be a concern for longer events. It offers excellent smart features and accurate HR, but you must have an iPhone.
What battery life do I need for a Hyrox race?
A full Hyrox race typically lasts under 2 hours, so any tracker with >10 hours of GPS battery life will suffice easily. However, for training and all-day wear, aim for 7+ days of smartwatch battery.
Are fitness trackers for Hyrox waterproof?
Most are water resistant to at least 5 ATM (50 meters), which is fine for sweating in rain or water stations. The Suunto Race and Garmin Instinct 2 Solar offer 10 ATM, ideal for heavy water exposure.
The verdict
