Key Terms

3 terms
vo2 max medical
"additional training insights like VO2 max and power curve"
VO2 max is the maximum amount of oxygen a person’s body can use during intense exercise, measured in milliliters per minute per kilogram of body weight. Think of it as a vehicle’s engine size for endurance: higher VO2 max means better aerobic capacity and sustained performance. Investors care because it’s a standard, objective metric used to evaluate fitness products, clinical outcomes, wearable accuracy, and health-related market claims that can affect sales and regulatory scrutiny.
fiber-reinforced polymer technical
"titanium bezel and lightweight fiber-reinforced polymer case"
A fiber-reinforced polymer is a composite material made of strong fibers (such as glass, carbon, or aramid) embedded in a polymer resin matrix; the fibers carry most of the load while the resin holds them in place and transfers stress between fibers. It combines high strength-to-weight ratio and resistance to corrosion compared with many metals, but its properties depend on the type, orientation and volume of fibers and the specific resin used, so performance can vary widely between products and applications.
atm water resistance rating technical
"a 10 ATM water resistance rating enables confident use"
A rating in atmospheres (ATM) that indicates how much external static water pressure a sealed device—commonly a wristwatch—can resist under laboratory conditions; 1 ATM equals the pressure exerted by a 10-meter column of water at sea level. It is a test-based measure of pressure resistance, not a literal safe diving depth: higher ATM numbers mean the case and seals are designed to withstand greater pressure, but real-world activities (movement, temperature changes, aging seals) can change actual water resistance. Common practical interpretations used in product specs are that low ATM values cover splashes and rain, mid-range values allow swimming and surface water sports, and high values are required for diving, but the rating itself only describes resistance to static pressure in testing conditions.

Comprehensive power modes, enhanced stamina metrics, a ComfortFit Fabric Band and Garmin Epic help endurance athletes and multiday adventurers train, race and explore even farther

OLATHE, Kan., Oct. 6, 2026 /PRNewswire/ -- Garmin (NYSE: GRMN) today announced Enduro™ 4, its longest-lasting GPS smartwatch with solar charging, which includes dynamic features and capabilities to take endurance enthusiasts farther on their next expedition. Utilizing an energy-efficient 1.4" MIP display in combination with a solar lens, Enduro 4 has up to 320 hours of battery life in activity mode1 or up to 90 days of battery life in smartwatch mode2. It also leverages innovative updates like grade-adjusted pace-based workout targets, grade-adjusted rolling pace, stamina zones, stamina curve and Garmin Epic multiday activity logging.

Comprehensive power modes, enhanced stamina metrics, a ComfortFit Fabric Band and Garmin Epic help endurance athletes and multiday adventurers train, race and explore even farther.

"As interest and participation in ultra-endurance activities continue to grow, Enduro 4 is designed for athletes and adventurers who want gear they can trust to perform through every mile, every climb and every challenge. Intuitive features like comprehensive power modes make the most of the long-lasting battery life, while grade-adjusted metrics add a new dimension to preparing for hilly or mountainous terrain."
—Susan Lyman, Garmin Vice President of Consumer Sales and Marketing

Grade-adjusted features, stamina metrics and more

In addition to 100+ activity profiles, Enduro 4 introduces new capabilities to the Enduro line, optimized for trail runners, multiday hikers and backpackers, and endurance athletes.

  • Comprehensive power modes provide preset options to optimize battery life and performance based on the needs of the user. Configurations include Max Accuracy, which offers full-feature tracking for shorter efforts, and Max Battery, ideal for extended activity recording (up to 320 hours with solar charging).
  • Grade-adjusted pace-based workout targets help athletes maintain the right effort range on hilly terrain, while grade-adjusted rolling pace provides a real-time view of pace over varying terrain.
  • Stamina zones show athletes how their stamina impacts an activity, and stamina curve helps users understand how their endurance changes over time based on fitness and training history.
  • With 50% more RAM than Enduro 3 and a more powerful, updated map engine, navigation is easier than ever with 30% faster panning and a smoother, more intuitive map interface for built-in routable maps. Perspective view provides more detail, both close-up and further away, allowing users to better anticipate what comes next.
  • Garmin Epic allows athletes to combine multiple activities into one cohesive story in Garmin Connect™. Activities can be grouped together over days, weeks or months to create an "Epic", which enables users to add photos and share with family and friends, as well as see health and performance data aggregated during that period.
  • Enhanced rowing tools provide additional training insights like VO2 max and power curve for indoor rowing activities, while expanded rucking features let users adjust pack weight during an activity and set target metrics like calories burned.

Premium design for maximum versatility

Enduro 4 weighs in at an incredible 66 grams, making it one of the lightest ultraperformance smartwatches on the market. With a 51mm case, Power Sapphire™ scratch-resistant lens, titanium bezel and lightweight fiber-reinforced polymer case, it is built for the demands of the longest races and most taxing adventures, remaining remarkably light on the wrist. An integrated LED flashlight includes both white and red-light options, while a 10 ATM water resistance rating enables confident use in challenging environments.

New to Enduro 4, the ComfortFit Fabric Band combines exceptional comfort, durability and moisture-wicking performance with QuickFit™ functionality, making adjustments and swapping bands even simpler. 64 GB of memory gives users more room for onboard maps, music and data, making it easier to stay prepared for extended adventures away from home.

Available now, Enduro 4 has a suggested retail price of $899.99. Learn more at Garmin.com.
