Connect your current device
Import runs from Garmin Connect, direct Samsung Health sync, Apple HealthKit, or Google Health Connect. TT trusts one source per run to prevent duplicates.
AI run analysis that reads GPS, heart rate, pace, and laps.
Train for a 10K or half marathon PB, then stay consistent with your crew.
No manual entry and no screenshots to explain. Connect the device you already use, go for a run, and TT Runner turns the evidence into a clear next action.
Import runs from Garmin Connect, direct Samsung Health sync, Apple HealthKit, or Google Health Connect. TT trusts one source per run to prevent duplicates.
TT reads GPS tracks, heart rate, pace, and laps together to calculate VDOT, heart-rate drift, and grade-adjusted pace.
See training paces that match your current fitness and recovery. Plan changes only apply after you review and confirm them.
Split your crew into teams and compete on distance. The most effective motivation to get everyone running.
No need to paste screenshots into GPT — TT analyzes your raw run data directly. VDOT, heart-rate drift, grade-adjusted pace (GAP), and aerobic effect, all reported automatically.
Recommends today's intensity from resting HR, HRV, and stress (Garmin). Ease off on recovery days, push on good ones.
Personalized VDOT-based paces with a fresh workout each week. Intensity adapts to your condition and injuries — but you always confirm before it applies.
Automatic PB tracking from 1K to marathon. See where you stand with regional and distance-band mileage rankings.
Auto-tallied crew stats show who ran the most. A little friendly competition keeps everyone consistent.
Track mileage and lifespan per shoe, and browse the 2026 catalog to find your next pair.
Connects with Garmin webhook, direct Samsung Health sync, Apple HealthKit, and Google Health Connect. COROS·Polar·Suunto come in via the health bridge, and each run trusts a single device to avoid duplicates.
Average pace alone cannot tell you whether a run went well. Hills, heart-rate change, and segment pacing give the context you need to plan the next workout.
Actual results vary with your run data and personal condition.

The answer is not to run faster every day. TT uses your current VDOT, weekly load, and recovery status to separate the sessions that build fitness from the days that should stay easy.
Use pace zones calculated from recent results to set tempo and interval intensity. Keep hard and easy days distinct so every quality session has a purpose.
A half marathon depends on accumulated training, not one fast run. Review weekly mileage, long-run continuity, and heart-rate trends to judge whether goal pace is realistic.
You do not need a new recording habit. Bring completed runs from your current device into TT Runner for analysis, crew activity, and PB tracking.
Enter a recent race result to see your Easy, Threshold, and Interval paces plus equivalent race predictions.
Calculate VDOT →See how direct analysis of GPS, heart rate, pace, and laps differs from summarizing a running screenshot.
Read how it works →Learn the purpose of Easy, Marathon, Threshold, Interval, and Repetition paces and when to use each one.
Explore training paces →Build a repeatable crew rhythm from member invitations and weekly runs to friendly crew battles.
Read the crew guide →Yes, it's free to start on both iOS and Android. You can use it solo just for PB tracking and AI run analysis, without a crew.
You don't need to paste run screenshots into GPT. TT Runner analyzes raw data — GPS tracks, heart rate, pace — directly in the app to compute VDOT, training pace zones, and interval segments, and generates a report every week.
It supports Garmin (direct webhook), direct Samsung Health sync, Apple HealthKit, and Google Health Connect. COROS, Polar, and Suunto can be imported through the health bridge. Each run trusts a single device by start time to prevent duplicate records.
VDOT, training pace, heart-rate drift, grade-adjusted pace (GAP), aerobic effect, and weekly recovery status. Training plans are rule-proposed and AI-explained — only adjustments you confirm are applied to next week's plan (never automatically).
Weekly team competitions where crew members compete on distance and PBs. Distance and records are tallied automatically and ranked on a leaderboard, so even people who rarely run on their own stay consistent.
Best times for 1K, 5K, 10K, half, and full marathon are detected automatically from your runs. You can also enter them manually, and values you set always take priority over auto-estimates.
Yes. TT Runner uses VDOT calculated from recent runs and PBs to suggest personal Easy, Threshold, and Interval paces. It does not guarantee a target time; it helps you choose the next run with your current condition and training history in view.
Yes. Connect Garmin Connect and completed runs sync through a webhook for analysis. You can also import through Apple HealthKit on iPhone or direct Samsung Health sync and Google Health Connect on Android.
Works great solo for PB tracking too.
