Frequently Asked Questions About GPS Running Watches
Giải đáp nhanh các thắc mắc phổ biến về công cụ và kỹ thuật chạy bộ.
Should I choose an AMOLED or Transflective MIP running watch display?
AMOLED displays (such as Garmin Forerunner 165, 265, 965, COROS Pace Pro, Suunto Race) deliver vibrant colors, high resolution for detailed topographic maps, and great indoor visibility, though Always-On mode reduces battery life. Transflective MIP screens (COROS Pace 3, Forerunner 255, 955, Enduro 3) reflect direct sunlight for glare-free outdoor visibility and ultra-long battery life without needing wrist-gesture wake.
Do I really need Dual-Frequency (L1 + L5) Multi-Band GPS?
If you frequently run through dense urban canyons with tall buildings, under thick tree cover, or on mountain switchbacks, Dual-Frequency L1+L5 GNSS significantly reduces multipath signal reflection and delivers much cleaner tracklogs and instant pace stability than single-band GPS.
What case size fits smaller 14.5 – 16.0 cm wrists best?
For 14.5–16.0 cm wrists, look for 41–43mm cases (COROS Pace 3 at 41.9mm, Garmin Forerunner 165 at 43mm, Forerunner 265S at 42mm) or slim 45–46mm models under 12.5mm thick paired with a nylon hook-and-loop band (COROS Pace Pro, Suunto Race S) to prevent optical HR sensor bounce and ensure 24/7 sleep comfort.
How many GPS battery hours do I need for a Marathon vs a 100K Ultra Trail?
Any watch with 15–20 hours of GPS battery easily covers a road Full Marathon (3 to 6.5 hours). For 50K, 70K, or 100K Ultra Trail races (12 to 28+ hours on course with live GPX navigation), aim for at least 30–38 hours of continuous GPS endurance.
