Strava running tracks how fast you run, how hard the run was, and why you keep training. Pace measures speed, effort measures strain, and purpose tools support consistency. Strava, a GPS fitness app for runners, calculates pace from distance and moving time. It then adds adjusted pace, effort scores, and goal tools to guide daily decisions.

How does Strava measure pace?
Strava calculates running pace from GPS distance divided by moving time. According to Strava Support, it reports average pace plus per-kilometre or per-mile splits for pacing analysis in Strava Support pace guidance.
Splits let you see steady miles, fast finishes, and slow sections. A 5:30 first kilometre followed by 6:10 climbs shows where hills or fatigue changed speed.
What does Grade Adjusted Pace tell you?
Grade Adjusted Pace, called GAP, estimates the equivalent flat-ground pace for a hilly run. According to Sci-DANI analysis, it adjusts actual pace for uphill and downhill gradient in Sci-DANI analysis of Strava GAP.
Use GAP to compare hilly and flat runs fairly. A 6:00 hilly pace with a 5:30 GAP equals about the same output as a 5:30 flat pace.
How are effort and recovery tracked?
Strava scores intensity with Relative Effort, which measures time in heart-rate zones relative to maximum heart rate. According to Strava Support, it weights that zone time into one workout score in Strava Support on Relative Effort. Runners without a heart-rate monitor can rate a run, ride, or swim from 1 to 10 with Perceived Exertion.
Perceived Exertion works as a substitute for heart-rate-based tracking. Strava combines those effort inputs into Fitness and Freshness charts. The charts track rising fitness, accumulating fatigue, and recovery needs over weeks and months.
How accurate are the numbers?
Pace, GAP, and Relative Effort depend on GPS, elevation, sensor data, and zone settings. Wrong maximum heart rate, wrong zones, or wrist-sensor errors distort scores.
Check these points before trusting a strange result: Strava also supports purpose through weekly distance or time goals, monthly challenges with digital badges, clubs, and segment leaderboards. Fix the sensor or zone setting first, then follow the trend across several weeks.
- Compare the map route with known distance when GPS looks jumpy.
- Confirm maximum heart rate and zone boundaries match current fitness.
- Treat one high effort score as a signal, not proof of lost fitness.
- Use GAP for routes, and Relative Effort plus Fitness and Freshness to balance hard and easy days and avoid overtraining.
