Score every run.
And every walk.

Rundown turns every Strava run and walk into a single 0–100 score — graded on the metrics that actually mattered for that session. One honest number. No dashboard to decode.

The Rundown Score

One number for every
activity. 0 to 100.

A 4×400 rep workout, a Sunday long run, and a weighted ruck aren't graded the same way — so Rundown swaps the metrics it scores based on what you actually did.

Great run · Easy

An easy run is about restraint.

If your heart rate stayed in Zone 1–2 and your pace didn't creep up, you ran easy. If it didn't, you didn't.

  • Zone AdherencePrimary signal

    How much of the run sat inside the easy-zone HR target — and how far above when you drifted.

    % in target zone% above targetAvg HR
  • HR Drift

    Late-run heart-rate creep at the same pace — the giveaway that an "easy" run was actually a tempo.

    Overall drift %First half HRSecond half HR
  • Pace Discipline

    Steady pace, no surges. Variability matters more than absolute speed here.

    Avg paceSpeed CVZone fit

A tempo lives in the discomfort zone.

You're trying to spend a long time at threshold — Zone 4 — without falling out the top of it. Did you hold it, or did it hold you?

  • Tempo SustainPrimary signal

    Time spent at or above your tempo threshold, and whether HR stayed steady or spiked.

    % at Zone 4+Avg HRPeak HR
  • HR Drift

    The whole point of a tempo is metabolic. If HR drifts 6–8 bpm at the same pace, the effort wasn't sustainable.

  • Pace Discipline

Intervals are graded rep-by-rep.

Anyone can crush rep one. The scoring asks whether rep six looks like rep one — and whether you actually recovered between them.

  • Work QualityPrimary signal

    How fast and clean the working reps were — bursty starts cost you here.

    Work paceBurst countWork-phase CV
  • Interval Consistency

    Rep-to-rep variance. A 1:32 / 1:34 / 1:31 / 1:48 set is not the same workout.

  • HR Recovery

    How fast your HR fell between reps. Faster recovery, fitter engine.

    Drop rate (bpm/min)Peak HRFinal HR

The long run is judged at minute 90.

Everyone holds pace for the first 5K. Whether the last quarter looks like the first is the whole game.

  • Aerobic EfficiencyPrimary signal

    Meters per heartbeat. Cardiac drift hides here — same pace, climbing HR, falling efficiency.

    m / beatAvg HRTotal beats
  • Fueling Signal

    Pace fade between the first and last quarter of the run. A clean long run holds within 3–4%.

  • HR Drift

    How much your engine fought you in the back half. Big drift on a long run = under-fueled or under-trained.

Race day has one job: execute.

The plan was the plan. Heat, hills, and pacing get accounted for — but the score is mostly about whether you ran the race you said you'd run.

  • Pace ExecutionPrimary signal

    How close you ran to your target race pace — with credit for negative splits, penalty for a positive split.

    Avg paceSession fitSpeed CV
  • Zone Adherence

    Distance-appropriate effort zones. A 5K should live above threshold; a marathon shouldn't.

    % in target zoneAvg HR
  • Conditions Adjustment

    Heat, humidity, dew point, elevation gain. Credit where the day was working against you.

    TemperatureDew pointElevation gain

Recovery has the opposite job.

Going slow is the workout. The score rewards low intensity and punishes the urge to "just push it a bit."

  • Recovery IntensityPrimary signal

    How much of the run sat below the easy threshold. Cross above it for more than a minute and the score drops.

    % easyMax HRThreshold
  • Zone Adherence

    Time in Zone 1. There's no upper-zone work on a recovery day.

    % in Zone 1Avg HR

Some sessions also factor in Consistency Streak (your hard/easy ratio across the past 14 days) and Conditions Adjustment (heat & humidity). The session-specific metrics above are what move the needle most.

Walks are scored on what makes a walk count.

Rundown auto-detects whether you walked casually, briskly, climbed, or carried weight — and grades all of them on the same five pillars. Long enough, in zone 2, with steady cadence, real climbing, and meaningful load wins the day.

  • Zone 2 AdherencePrimary signal

    Share of moving time in HR zone 2 — the aerobic-base sweet spot for walking. Wander up into Z3 and the score nudges down.

    % in Z2Avg HRTime above Z2
  • Cadence Quality

    How steady your step cadence held against your typical walking rhythm. Stride consistency is the difference between a walk and a stroll-with-stops.

    Avg cadenceCadence CVPersonal baseline
  • Elevation Gain

    Vertical metres climbed per kilometre — uphill load earned by this walk. Climbing turns a flat stroll into real aerobic work.

    Total gainm / kmAvg grade
  • Load Stimulus

    Cumulative weekly load (pack or vest weight × minutes) toward your stimulus target. Carrying weight under zone 2 builds durability without the breakdown cost of running.

  • Duration

    Total walk time relative to your daily zone-2 minute goal. Short and sweet still counts — but minutes in zone are the cardio currency.

Everything in the beta

More than a score.

The score gets you in the door. What keeps you here is everything Rundown does with your runs and walks once they're connected.

Adjusted Pace

A grade- and weather-adjusted pace next to the raw one — so a brutal 28 °C hill run reads as the effort it actually was.

Shoe mileage & gear

Assign a shoe to each run and Rundown tracks the miles — and tells you when a pair is due to retire before your knees do.

Fuel logging

Log gels, drinks and food against each run or walk — so the long-run fade finally has an explanation.

The full breakdown

Every sub-number behind the score, with weather and route stats — plus a plain-English suggestion for next time.

Pillar trends

Watch each metric move over time — zone adherence, drift, efficiency, walk cadence — runs and walks separately.

Compare & map

Context, not just a lonely number — every run mapped and set beside a comparable one from your own history.
