Every run you've done with your Apple Watch — distance, pace, heart rate, VO2Max, power — is analyzed to understand your current fitness state.
Your VO2Max and performance history are modeled with exponential decay — recent data is weighted more heavily than old data, giving an accurate picture of where you are today.
Choose your target distance (5K to marathon), target time, target date, and which days you want to run. RunRight calculates the path from where you are to where you want to be.
Complete a run faster than planned? Next workout intensity increases. Miss a scheduled run? The plan recalibrates your timeline and volume. This is coaching, not a PDF.
50% of weekly distance at 75% VO2Max. Builds your endurance foundation.
60% of remaining distance at 90% VO2Max. Builds speed endurance and lactate threshold.
40% of remaining at 110% VO2Max with 600m repeats. Builds raw speed and cardiovascular capacity.
RunRight reads your running history, pace, heart rate, and VO2Max from Apple Health. Our AI algorithm models your current fitness state using VO2Max with exponential decay, then generates a weekly plan with the right mix of long runs, tempo runs, and intervals tailored to your goal.
Generic plans follow a fixed schedule regardless of your fitness level or progress. A personalized plan from RunRight adapts after every run — if you overperform, intensity increases; if you miss a run, the plan recalibrates. It uses your actual VO2Max and heart rate data, not self-reported fitness levels.
RunRight reads running workouts, VO2Max, heart rate samples, active energy, and running power from Apple Health via HealthKit. No manual logging is required — your Apple Watch records everything automatically.
An Apple Watch is recommended for the best experience as it provides VO2Max, heart rate, and running power data. However, RunRight can also work with basic iPhone running data and estimated metrics.
