Every run your Apple Watch has recorded — distance, pace, heart rate, VO2Max — is analyzed to assess your current fitness and threshold.
Target time, race date, available training days. RunRight calculates the path from your current level to your goal.
Long run, tempo run, intervals, easy run — every workout is dosed to your threshold with a maximum 25% volume increase per week.
Ran faster than planned? Intensity goes up. Missed a workout? The plan recalibrates. This is coaching, not a spreadsheet.
50% of weekly volume at 75% VO2Max (easy effort). Builds the endurance to sustain 26.2 miles on race day.
At 85-90% threshold (half marathon pace). Develops your ability to hold a strong pace over long distances.
Sets of 600m at 110% VO2Max. Improves your lactate threshold and cardiovascular capacity.

Try RunRight freeA marathon training plan typically lasts 12 to 16 weeks for runners who already run regularly. First-time marathoners should allow 16-20 weeks. RunRight adjusts the plan duration based on your current fitness level and race date.
A sub-3:30 marathon requires holding roughly 4'59"/km (8'02"/mi) — about 12 km/h. That corresponds to around 75-80% of your VO2Max, meaning you need a VO2Max of at least 50-52 ml/kg/min. RunRight calculates your race prediction based on your actual VO2Max from Apple Watch.
Weekly mileage depends on your goal and experience. First marathon: 25-40 miles/week at peak. Sub-3:30 goal: 40-50 miles/week. Sub-3:00 goal: 45-60 miles/week. RunRight builds volume progressively with a maximum 25% increase per week to prevent injury.
A balanced marathon plan includes: a long run (50% of weekly volume), tempo runs at 85-90% threshold (half marathon pace), long intervals (1000m repeats at 95%), and easy runs (60-65% effort). RunRight generates this optimal mix automatically based on your fitness data.
