Record runs right in the app. GPS tracking with live distance, pace, and vert, no watch needed, and your run lands in your log with honest terrain-based elevation. Your plan now tells you the truth about your week. Ahead, on track, or behind based on what the plan actually scheduled through today, a recap when the week wraps, and workouts that go beyond the plan get called out for what they are. Also in this update: collapsible plan weeks for faster scrolling, plan tuning moved onto the plan page, strength days you can add to any plan day, and layout fixes across iPhone sizes.
