Why the Garmin Forerunner 570 is My #1 Fitness Purchase of 2025

Four months ago, I dropped $550 of my own money on the Garmin Forerunner 570, and it's honestly the best fitness investment I've made all year. More than my expensive carbon wheels, more than my new road bike components, more than any other training gear – this watch has genuinely transformed how I approach fitness and made me the healthiest I've ever been.

But here's the thing – the Forerunner 570 definitely isn't for everyone. At $550, it's a serious investment, and there are some genuine drawbacks you need to know about before buying. After wearing it every single day for four months, including through my Ironman 70.3 training, I'll give you the complete honest breakdown of what it's actually like to live with this watch.

Quick Verdict: 4.7/5 Stars

The Garmin Forerunner 570 is an exceptional fitness watch that excels at endurance training, recovery monitoring, and daily health tracking. The battery life, training guidance, and comprehensive metrics make it outstanding for serious athletes. However, the high price and some durability concerns prevent it from being perfect.

Best for: Serious endurance athletes, triathlon trainers, and fitness enthusiasts who want comprehensive health monitoring.
Skip if: You're a casual fitness user, budget-conscious, or primarily want smartwatch features over fitness tracking.

Why I Chose the Forerunner 570

Coming from an Apple Watch Series 9 that I'd worn daily for over a year, I thought I had everything I needed. Then I completed my first Ironman 70.3, and reality hit hard. By race finish, my Apple Watch was down to 15% battery. With a full Ironman planned for next year, lasting potentially 10+ hours, the Apple Watch simply wouldn't cut it.

The Garmin Forerunner 570 solved this immediately with its impressive 11-day battery life. But more importantly, the 42mm case size fits my smaller wrists perfectly. After trying larger Garmin models in store, they looked like dinner plates on my wrist. This size strikes the perfect balance between screen real estate and wearability for 24/7 use.

The transition from Apple Watch was easier than expected, and within a week, I knew I'd made the right choice for my training goals.

Daily Features That Actually Matter

Customizable Watch Face Intelligence

The watch face customization goes far beyond aesthetics. I've configured mine to display the metrics I actually care about: battery indicator, current VO2 max, heart rate, and training readiness score. The multicolored training readiness bar isn't just pretty – it's become my daily guide for workout intensity decisions.

My VO2 max sits prominently in the top right, currently at 51. Watching this number slowly climb feels like leveling up in a game. My goal is reaching the top 1% for my age group (VO2 max of 65), and having this constant reminder keeps me motivated during tough training sessions.

Training Readiness: Your Wrist-Based Coach

This feature alone justifies the Garmin Forerunner 570 price tag for serious athletes. The training readiness score combines sleep quality, heart rate variability, recovery time, training load, and stress levels into one actionable number.

Last year, my biggest problem was overtraining. I'd get enthusiastic, train too hard, get injured, then lose weeks of progress recovering. The training readiness score has largely eliminated this cycle by giving me objective data about when to push hard versus when to ease back.

The system is remarkably responsive. After a poor night's sleep or intense workout, my readiness drops appropriately. Take an afternoon nap, and it increases a few points. While I don't follow it blindly – sometimes I feel great despite a low score – it provides valuable insight I'd otherwise miss.

Personalized Training Plans

Having logged my next Ironman 70.3 into the watch, it created a comprehensive training plan tailored to my target finish time of under 5 hours. The Garmin Forerunner 570 intelligently schedules longer brick workouts on weekends when I have more time, while keeping weekday sessions manageable.

What impresses me most is the adaptability. If I extend a recommended 45-minute ride to 2 hours, the watch adjusts subsequent workouts based on my actual training load and recovery status. This flexibility prevents the rigid structure that makes many training plans unsustainable.

The workout suggestions are specific and purposeful – "45 minute threshold bike ride at 235 watts" rather than vague "moderate intensity" guidance. For structured training, this precision is invaluable.

Morning and Evening Routines

The morning report has become my daily health briefing. Two metrics matter most to me: sleep quality (scored out of 100) and days remaining until my race. The sleep tracking keeps recovery at the forefront of my mind – you can't improve what you don't measure.

The race countdown creates psychological urgency that keeps training consistent. When my trainer asked how many days until my Ironman, I immediately answered "86 days" because that number is reinforced every morning.

The evening routine reminds me to start winding down at 9 PM. Most people set morning alarms to wake early, but setting a bedtime reminder is more effective. If you sleep earlier, waking early becomes natural rather than forced.

What Doesn't Work So Well

The Price Reality Check

At $550, the Garmin Forerunner 570 is expensive, especially when the previous generation Forerunner 265 regularly sells for around $350 with 90% of the same features. Being only four months old, the 570 rarely sees discounts, making the 265 a smarter financial choice for most people.

That said, I don't regret the purchase. Health is the foundation for everything else in life, and this watch directly improves my health outcomes. Plus, I use it constantly throughout every day – it's essentially a 24/7 personal trainer and health monitor.

Daily Annoyances

The watch buckle occasionally scratches my laptop during long typing sessions. It's a minor issue solved by removing the watch while working, but it's an unexpected inconvenience for desk workers.

After four months of daily wear, micro-scratches have appeared on the display. At this price point, I'd expect sapphire glass for better scratch resistance. The scratches aren't visible during normal use, but they're disappointing on a premium device.

Durability Concerns

While the watch has held up well overall, the lack of sapphire glass remains concerning for long-term durability. These micro-scratches suggest the display may show more significant wear over years of use, especially for active users who don't baby their equipment.

Forerunner 570 vs Major Competitors

vs. Apple Watch Series 9

The Apple Watch excels at smartwatch features, app ecosystem, and daily convenience. However, for serious fitness tracking, the Garmin Forerunner 570 wins decisively. Battery life alone makes it superior for endurance events, while the training metrics and recovery guidance are far more sophisticated.

Choose Apple Watch if you want a general-purpose smartwatch that does fitness tracking.
Choose Garmin if fitness tracking is your primary goal with some smart features as bonus.

vs. Garmin Forerunner 265

The 265 offers about 90% of the 570's functionality at significantly lower cost. Key differences include some advanced metrics, slightly better display, and newer software features. For most users, the 265 represents better value.

Choose the 570 if you want the absolute latest features and don't mind paying premium pricing.
Choose the 265 if you want excellent Garmin functionality at a more reasonable price.

vs. Polar Vantage V2

Polar offers excellent heart rate accuracy and recovery metrics at a lower price point. However, Garmin's ecosystem, training plans, and overall user experience are more polished. The Garmin Forerunner 570 provides more comprehensive daily guidance.

Frequently Asked Questions

Is the Forerunner 570 worth the extra cost over the 265?
For most people, no. The 265 provides excellent functionality at a much better price point. Only choose the 570 if you specifically want the latest features and don't mind paying a premium.

How accurate is the VO2 max measurement?
While not as precise as lab testing, most users report accuracy within 2-3 points of professional measurements. It's reliable enough for tracking fitness improvements over time.

Can casual fitness users benefit from this watch?
The Garmin Forerunner 570 is designed for serious athletes and may overwhelm casual users. Consider the Garmin Venu series or stick with the Forerunner 265 for more basic fitness tracking needs.

How does battery life perform in real-world use?
The advertised 11-day battery life is accurate with moderate GPS usage. Heavy training weeks with daily GPS tracking might reduce this to 7-8 days, still excellent for any smartwatch.

Is the 42mm size suitable for larger wrists?
The 42mm case works well for average to smaller wrists but may look undersized on larger wrists. Try the watch in person if possible, as size preference is highly individual.

Final Recommendation

The Garmin Forerunner 570 represents the current pinnacle of fitness tracking technology, delivering comprehensive health monitoring, intelligent training guidance, and exceptional battery life. For serious endurance athletes, triathletes, and dedicated fitness enthusiasts, it's genuinely transformative.

However, the high price point and incremental improvements over the Forerunner 265 make it difficult to recommend universally. Most users would be better served saving money with the previous generation.

If you're training for specific events, want the most advanced recovery guidance available, and can justify the premium pricing, the Garmin Forerunner 570 will likely become your most valued training tool. Just be prepared for the sticker shock and some minor daily annoyances.

For everyone else, wait for price drops or consider the excellent Forerunner 265 as a more budget-friendly alternative that still delivers professional-grade fitness tracking.
