Your hill score helps you understand your current capacity for uphill running based on your training history and a VO2 max. estimate from the last two months. Your watch detects uphill segments with 2% grade or more during an outdoor running, walking, or hiking activity. You can view your hill endurance, hill strength, and changes to your hill score over time.
