🏁 My Recommendation

For most everyday athletes, the Forerunner 265 hits the sweet spot. It delivers advanced training features, full triathlon support, and excellent battery life at a price point that makes sense for serious hobbyists. The AMOLED display and training readiness features genuinely help you train smarter without overwhelming complexity.

If you're a serious multisport athlete who trains across multiple disciplines, competes regularly, and values navigation and communication features, the 970 is worth the investment. The offline maps, voice calls, and advanced running metrics provide tangible benefits for committed athletes.

New to running or GPS watches? The 165 gives you the Garmin ecosystem, AMOLED display quality, and core training features at the most accessible price. It's perfect for building the habit before investing in advanced metrics.

🧩 Final Thoughts

The Forerunner series proves that Garmin understands runners and triathletes at every level. Whether you're chasing your first 5K or competing at Ironman distance, there's a Forerunner built for your goals.

Technology should simplify training, not complicate it. These watches succeed by making data actionable - telling you when to push hard, when to rest, and how to improve without requiring a PhD in exercise physiology.

Choose based on your current needs and near-term goals. You can always upgrade later, but the best watch is the one that motivates you to train consistently now.
