Loved by Early Testers

As a runner, I live by my data. The RACER 4 is surprisingly accurate. The real-time heart rate zones have totally changed how I approach my training runs. It feels like I have a personal coach on my wrist.

Love the watch, battery is amazing, and the screen is gorgeous. Just wish the strap came in more colors out of the box. Still, an easy recommendation for any serious runner. The value is unbeatable.

I've used watches from the big brands that cost 3x as much, and the RACER's AMOLED screen is just as good, if not better. The value here is insane. Finally, a watch that feels premium without emptying my wallet.

Honestly, I was sold on the look first! I got the Alpine Green and get compliments all the time. It's super lightweight and comfortable to wear 24/7, from the gym to the office. It doesn't scream 'sport watch,' it just looks cool.

I was skeptical at first, given the price point. But from the easy setup to the bright, responsive screen, this watch has exceeded all my expectations. It tracks my workouts perfectly and the core smart features are flawless. Genuinely impressed.

Have questions?

What are the main differences between the Runmefit RACER 3 and RACER 4?

Both the RACER 3 and RACER 4 are expert-level GPS watches built for runners, but they cater to slightly different needs.

The RACER 3 is your perfect daily running partner. It features an ultra-lightweight design, precise GPS and heart rate tracking, and up to 14 days of battery life, making it ideal for 5k/10k training and daily wellness monitoring.
The RACER 4 is built for advanced runners and data enthusiasts. It includes all the features of the RACER 3 and steps up with Advanced Running Dynamics (tracking metrics like cadence, stride length, and vertical oscillation), SpO2 Blood Oxygen monitoring, and an even longer battery life in GPS mode. It's the ultimate tool to scientifically analyze and improve your running form, perfect for half and full marathon preparation.

Will RACER smartwatch work with my iPhone or Android phone?

Yes, absolutely. The RACER is compatible with most modern smartphones. It connects to iPhones running iOS 12.0 or later and Android phones running Android 7.0 or later via the "Runmefit" app.

Can I swim or take a shower with the RACER?

The RACER has an IP68 water and dust resistance rating. This means it is fully protected from dust and can handle splashes, rain, and brief, shallow submersion, like when washing your hands. However, an IP68 rating is not sufficient for swimming, diving, or showering. The high-pressure water jets in a shower and the steam from hot water can damage the device's seals.

How often will I need to charge the battery?

The RACER is designed to keep you going longer. On a single 2-hour charge, you can expect up to 15 days of battery lifewith typical use. For more intense usage with features like frequent monitoring, it lasts about 5 days. There is also a Battery Saver Mode that can extend the battery life up to an incredible 45 days, ensuring your watch is always ready when you are.

What health metrics can the RACER monitor?

The RACER offers a comprehensive suite of health monitoring tools, including 24/7 Heart Rate, Blood Oxygen (SpO2), Sleep Tracking, and Stress Monitoring.

Can I make and receive phone calls on the RACER?

Yes. The RACER features Bluetooth Calling. When connected to your smartphone, you can answer, reject, and initiate phone calls directly from your wrist using the watch's built-in speaker and microphone, offering you true hands-free convenience. You will also receive notifications for texts, emails, and apps.

Does it sync my health data with apps like Apple Health or Google Fit?

Yes, it does. The RACER is designed to integrate into your existing health ecosystem. Through the Runmefit app, you can seamlessly sync your health and fitness data with both Apple Health and Google Fit, keeping all your wellness information consolidated in one place.

The screen is listed as AMOLED. What does that mean for me?

The RACER features a stunning 1.43-inch, high-resolution (466x466) AMOLED display. Unlike standard LCDs, AMOLED screens produce deeper blacks, more vibrant colors, and superior contrast. This means your watch faces, stats, and notifications will look incredibly sharp, bright, and easy to read, even in direct sunlight.
