RunIntensity Support

Getting Started

RunIntensity is a smart training load management app for runners. It uses Apple HealthKit data to calculate your training intensity, track soreness, and determine workout readiness.

Initial Setup

  1. Sign In: Use Sign in with Apple to create your account.
  2. Grant HealthKit Access: Allow RunIntensity to read your workout, heart rate, HRV, resting heart rate, and sleep data.
  3. Set Your Profile: Enter your resting heart rate, max heart rate, and weight in Settings for accurate TRIMP calculations.

Features

Dashboard

Your home screen shows today's readiness score, recent training load, and current training phase. The readiness score factors in your recent workout load, heart rate variability trends, sleep quality, and soreness levels.

Workout History

View all your running workouts imported from Apple Health. Each workout shows distance, duration, average heart rate, TRIMP score, and intensity zone breakdown.

Soreness Tracking

Use the 3D body diagram to log soreness after workouts. Tap body regions to mark soreness levels (mild, moderate, severe) and add notes. This data feeds into your readiness calculation.

SAM Check-In

Rate your mood, energy, and motivation daily using the SAM (Self-Assessment Manikin) scale. These subjective wellness markers help refine your readiness score.

Personal Records

Track your best performances across different distances and workout types.

Coach Mode

Coaches can monitor multiple athletes' training loads, readiness scores, soreness reports, and SAM ratings. Athletes can link to a coach in Settings.

Frequently Asked Questions

Why isn't my workout data showing up?

Ensure you've granted RunIntensity access to Apple Health data. Go to iOS Settings > Privacy & Security > Health > RunIntensity and verify all permissions are enabled. Workouts must be recorded by Apple Watch or another HealthKit-compatible app.

How is TRIMP calculated?

TRIMP (Training Impulse) is calculated using your heart rate data during workouts, weighted by intensity zones relative to your resting and maximum heart rate. Higher intensity zones contribute exponentially more to your TRIMP score.

How is readiness determined?

Your readiness score is a composite of recent training load trends, heart rate variability, resting heart rate changes, sleep data, soreness levels, and SAM check-in ratings.

Can I use RunIntensity without an Apple Watch?

RunIntensity works best with an Apple Watch for automatic heart rate and workout data. Without a watch, you can still manually log soreness, SAM check-ins, and view workouts recorded by other HealthKit-compatible devices.
