Strava Segment Comparator

Compare segments between two Strava activities

Find out exactly where you gained, or lost, time. Strava Segment Comparator lines up two Strava activities segment by segment: your ride against a friend's, or today's run against last month's. One click gives you the net gap, who won each segment, and where the gap opened up. WHAT YOU GET • The verdict up front: the net time gap, segments won and lost, and your biggest losses and gains by name • Where the time went: a course-order chart of the running total. One bad climb, or a slow leak everywhere? • Every segment side by side: time, speed or pace, power, heart rate and VAM, each with its difference • Fair gaps: Time Diff % shows each difference as a share of the segment, so a sprint counts as much as a long climb • Form: reads time against heart rate. Faster at a lower heart rate is Fitness; faster at a higher one is Effort • Your PRs and history: how far off your personal record each effort was, where it ranks among all your efforts, and a sparkline of your progress • My Activities Here: lists your other activities on the same segments, so finding a rematch takes one click • Rides and runs: speed for rides, pace for runs, km and miles mixed freely • Laps and overlaps handled: repeated efforts stay separate, and segments inside other segments can be left out of the total so no stretch of road counts twice EASY TO USE 1.
