Understanding PR Tracking

Muvri automatically tracks personal records (PRs) across all your routes and segments, giving you a complete picture of your performance without manual effort.

How PR Detection Works

Every time you upload or sync an activity with GPS data, Muvri:

  1. Analyzes the route to match it against previous activities
  2. Compares performance metrics (time, pace, power, etc.)
  3. Checks all custom segments you've created
  4. Detects new PRs and records them to your timeline
  5. Captures context: weather, gear, heart rate, time of day

This happens automatically—no manual logging required.

Types of PRs Tracked

Route PRs

Muvri identifies routes you've run or ridden before by matching GPS tracks. When you complete a familiar route faster than ever, it's automatically recorded as a PR.

Route matching considers:

  • GPS path similarity (allowing for minor variations)
  • Total distance (within 2% tolerance)
  • Start and end point proximity

Segment PRs

Segments are specific sections of routes that you want to track. Examples:

  • A challenging hill climb
  • A flat sprint section
  • Your local 5K loop
  • A technical descent on your MTB route

Once you create a segment, Muvri checks all your activities—past and future—for performances on that segment.

Distance PRs

Fastest times for standard distances:

  • Running: 1K, 1 mile, 5K, 10K, half marathon, marathon
  • Cycling: 10K, 20K, 40K, 100K, etc.
  • Swimming: 100m, 400m, 1500m, etc.

These PRs are detected regardless of route—any time you run 5K faster than before, it's recorded.

Creating Custom Segments

To create a segment:

  1. Open any activity with GPS data
  2. Click on the map to enter segment mode
  3. Drag the start marker to your segment's beginning
  4. Drag the end marker to the segment's finish
  5. Name your segment (e.g., "Oak Street Hill" or "Park Loop Sprint")
  6. Click "Save Segment"

Muvri will immediately:

  • Check all your past activities for this segment
  • Show you the leaderboard (your attempts ranked)
  • Highlight the current PR
  • Monitor future activities for new attempts
Pro Tip: Create segments for sections where you regularly push hard. This lets you track micro-improvements even when overall route times plateau.

Viewing Your PR Timeline

Your PR Timeline shows all personal records in chronological order. For each PR, you can see:

  • Date & Time: When you set the record
  • Performance metrics: Time, pace, power, heart rate
  • Improvement: How much faster than your previous PR
  • Context: Weather, temperature, gear used
  • Effort indicators: Heart rate zones, perceived effort

Click any PR to see the full activity and compare it with previous attempts.

PR Context and Analysis

Understanding why you set a PR is as important as knowing you did. Muvri captures:

Environmental Factors

  • Temperature and weather conditions
  • Wind speed and direction
  • Time of day (morning vs. afternoon performance patterns)

Training Context

  • Training load in the days/weeks before
  • Freshness score at the time
  • Recent workouts and recovery status

Gear Used

  • Shoes or bike used for the PR
  • Gear age and mileage at the time

This context helps you replicate successful conditions and understand performance patterns.

Ghost Racing

For saved segments, Muvri offers "ghost racing"—the ability to compete against your own past performances in real-time during a workout.

How it works:

  1. Start an activity on a route containing saved segments
  2. When you enter a segment, Muvri activates ghost mode
  3. See your current position vs. your PR attempt
  4. Get real-time feedback: "5 seconds ahead" or "3 seconds behind"

This feature is available on GPS watches and the Muvri mobile app (Plus plan).

PR Attempts vs. PRs

Muvri distinguishes between PR attempts and actual PRs:

  • PR: A new personal best
  • Attempt: Any effort on a tracked route or segment, whether or not it's a PR

Your dashboard shows PR attempts in the last 7/30 days—useful for understanding training consistency and when you're pushing limits.

Why Track Attempts?

Not every hard effort results in a PR, but attempts still provide value:

  • Show training progression even without PRs
  • Reveal performance consistency
  • Identify when you're close to breaking through

Common Questions

Why didn't Muvri detect my PR?

Common reasons:

  • GPS data was poor quality (too many gaps)
  • The route varied too much from previous attempts
  • The segment wasn't created yet (create it now—it'll check past activities)

See our troubleshooting guide for more details.

Can I delete or edit PRs?

Yes. If a PR was recorded incorrectly (e.g., GPS error showing impossible pace), you can remove it from Settings → PRs.

Can I see my all-time leaderboard?

Yes! Navigate to any segment or route to see your ranked attempts. Filter by date range, weather, or gear to analyze patterns.

Do PRs account for wind and elevation?

Muvri shows raw performance (actual time) but also displays normalized performance metrics that account for environmental factors. You can toggle between views.
