Adaptive weekly planning
The plan is built from the current training state rather than a fixed calendar.
Used in: weekly plan · replanningHOW PACE HELPS
What PACE does for your training.
From the first training block to race day: see how PACE plans your training, recognizes progress, evaluates workouts and turns that into the next useful stimulus.
TOP
Nine ways PACE connects training and race day.
If you only have two minutes: this is where PACE differs from a static plan or pure tracking.
01Training evolves with youPACE doesn't just plan week one; it responds to how you actually train.
02Your performance can move the targetsConfirmed progress can update training paces and forecast.
03PACE sees more than mileagePlan, actual execution, heart rate and perceived effort are interpreted together.
04Your race improves the next blockPacing, durability and race learnings feed back into training.
05Reach the start line with a strategyCurrent fitness, readiness and race learnings become a concrete race strategy.
06Interpret conditions correctlyHeat, wind and elevation help interpret pace and load more fairly.
07Use good days for good stimuliRecovery context helps decide when quality work makes sense.
08Workout straight to your wristStructured sessions with pace and heart-rate targets on Apple Watch.
09Return intelligently after breaksIllness or injury changes the return path without paying back old mileage.

PACE is in early access. Status labels show what already exists in the current product and what is still ahead.
01
Planning & adaptation
How PACE turns history, goals, availability and actual training into the next useful step.
Current
12-week history
Existing Apple Health runs establish baseline, volume and demonstrated capacity at setup.
Used in: onboarding · baseline · first planAutomatic volume capacity
Real weekly volume, frequency, long runs and demonstrated tolerance bound how quickly volume may grow.
Used in: weekly volume · long run · progressionMissed, extra and changed runs
PACE reassesses the remaining week instead of mechanically paying back missed mileage.
Used in: replanning · load managementTraining days & availability
Planned sessions are distributed across the days the athlete can actually train.
Used in: weekly structure · replanningRace-date periodization
Foundation, specific work, peak/taper and race week change priorities and workout mix.
Used in: training phase · taper · race weekGoal-aware planning
Goal time and current forecast can shape allowed priorities without artificially increasing the quality budget.
Used in: training focus · HM-specific workRecovery-aware planning
NORMAL, CAUTION and HIGH_FATIGUE can change volume and available quality; recovery takes priority over goal pressure.
Used in: daily decision · weekly replanningPost-race recovery
After a confirmed race, return to normal load is controlled rather than immediately jumping back to prior volume.
Used in: following week · return to normal load
02
Understand training & performance
Not just tracking: PACE compares plan and reality and uses the result downstream.
Planned-vs-actual step matching
Structured workout steps are matched against the segments actually completed.
Used in: workout analysis · target adherenceWorkout-specific analysis
Easy, long, threshold, HM pace, VO₂, hills and other workout types are evaluated with family-specific criteria.
Used in: analysis · response enginePace, heart-rate & completion assessment
Target ranges, completed distance/duration, heart rate, fade and other relevant metrics are interpreted together.
Used in: workout outcome · plan adaptationRPE & subjective feedback
Perceived exertion and relevant feedback can refine interpretation and trigger reanalysis.
Used in: analysis · recovery · responsePersistent analysis history
Previous workout and race analyses remain available with the same rich analysis payload instead of degrading into a reduced historical view.
Used in: analysis history · reviewCalibration & performance anchors
Races, tests and suitable workout results can update individual pace anchors.
Used in: threshold · HM pace · training targetsHalf-marathon performance forecast
Current performance evidence produces a model-based HM forecast with transparent data quality.
Used in: progress · training paces · race strategyForecast trend
Multiple forecast points show how the current performance anchor changes over time.
Used in: ProgressGoal feasibility
Goal time and current forecast remain separate; the desired goal does not simply become the performance anchor.
Used in: Progress · planning prioritiesPerformance drivers
PACE shows which factors support or limit the current forecast or race readiness.
Used in: Progress · coaching explanation
03
Race Intelligence
From race date to post-race analysis and back into the next training cycle.
Race readiness
Specificity, durability, consistency, freshness/taper, recovery, safety and fueling are evaluated separately and combined.
Used in: Progress · race proximity · training focusRace confirmation
A run is treated as a race only after explicit confirmation, not merely because of distance or pace.
Used in: performance evidence · race intelligenceSplits & race phases
Kilometer splits and race phases show pace, heart rate and changes across the race.
Used in: race analysisPacing & durability
Start behavior, first vs second half and late-race fade are interpreted separately.
Used in: race intelligence · training focusHeart-rate intensity vs HR trajectory
Absolute intensity and change across the race are deliberately kept separate.
Used in: race analysis · coachingRace learning loop
Learnings such as pacing discipline, HM durability or conditions adaptation persist and can shape later priorities.
Used in: next training cycle · race strategyAdaptive race strategy
Current forecast, readiness and retained race learnings produce pacing guidance and race cues.
Used in: race preparation · ProgressFueling rehearsal
Fueling practice and tolerance can be recorded on long/race-specific sessions and used in race readiness.
Used in: long run · race readiness · race coaching
04
Illness, injury & return
PACE separates uncomplicated return from situations that require professional guidance or assessment.
Training pause
During illness or injury, running and Watch prescriptions are paused while prior training history remains intact.
Used in: safety · planner · Watch syncLight return-to-running
After resolved mild issues, PACE starts with a short very easy check followed by three reviewed easy-return steps.
Used in: return-to-training · automatic plan handoffSeverity & warning signs
Systemic, significant, recurrent or abnormal responses block the normal self-guided return and escalate to professional assessment.
Used in: safety · pause policyClinician / physiotherapist parameters
When explicit external restrictions exist, the runtime can store and enforce distance, frequency, spacing and reassessment limits. This is not the normal consumer return flow.
Used in: professional return plan · workout planningNo catch-up after a pause
Missed mileage after illness or injury is not treated as debt to be repaid in the following week.
Used in: return · weekly planning
05
Workout execution & Apple Watch
From the planned workout to the imported result.
Structured workouts
PACE builds workout steps with distance/time and pace, heart-rate or effort logic depending on the session.
Used in: workout · Apple WatchWorkout types
Easy, recovery, long run, threshold, HM pace, VO₂, hills, long HM blocks, calibration, strides, race and rest have distinct roles.
Used in: periodization · training stimulusApple Watch / WorkoutKit sync
Planned structured sessions are sent to Apple Watch with stable plan IDs and reconciled after replanning.
Used in: workout execution · targetsHealthKit import
Apple Watch remains the recorder; PACE imports workout, heart rate, distance and running speed for analysis and replanning.
Used in: training history · analysis · engineStrength modules
Running-specific strength sessions include development/maintenance variants, sets/reps, RIR, rest, explanations and exercise visuals.
Used in: plan · workout · prehabMobility & stretching
Targeted mobility can precede quality sessions; optional stretching can follow easy/recovery sessions.
Used in: workout preparation · companion modules
06
Data, readiness & context
Which additional signals PACE does not merely display but actually interprets in decisions.
Multi-signal readiness
Sleep, HRV, resting heart rate, subjective state and training context are considered together.
Used in: readiness · recovery state · planningPersonal heart-rate anchors
Max HR, resting HR and derived training anchors help individualize easy/LT1/threshold and intensity interpretation.
Used in: targets · analysis · ProgressWeather data
Temperature/feels-like, humidity, dew point, wind and precipitation can be processed as environmental context.
Used in: workout interpretation · race contextElevation, gradient & altitude
RouteSummary uses elevation gain/loss, gradient, terrain fractions and mean altitude without sending the exact GPS route in the engine payload.
Used in: pace interpretation · analysis · race intelligenceEnvironment-aware pace interpretation
PACE does not use a universal weather penalty; heat, wind and terrain can shift how pace is weighed against heart rate/RPE.
Used in: workout analysis · response · replanningData confidence instead of guessing
Missing or uncertain data lowers analysis confidence; PACE does not treat absent signals as ideal execution.
Used in: analysis · positive progression
