Click any activity (from the dashboard, recent activity feed, or sport analytics) to open the detail page. URL pattern: /athlete/<id>/activity/<activity_id>/.

Sections

Summary header

Date, duration, distance, elevation, average HR, average power (if applicable), normalised power, IF, Load. Wellness logged that day appears as a small badge.

Map and elevation profile

If the file has GPS, the route is plotted. The elevation chart sits below.

Power and HR over time

The per-second chart. You can zoom and pan. Lap markers overlaid.

Laps table

Each lap with duration, distance, average power, average HR, average pace. Useful for interval sessions to see whether you held the prescription.

Zones distribution

Time in each power zone (bike) and HR zone (all sports). For swims, time per stroke type if the file has it.

Best efforts

The top efforts from this activity at 1s, 5s, 1m, 5m, 20m, 60m (for power) and equivalent for pace.

Segments

If the route passes any registered Segment, the segment effort appears here with comparison to your previous attempts.

Editing the activity

• Rename the activity.
• Change sport classification (if it was misidentified).
• Trim warm-up or cool-down.
• Mark warm-up — flag a whole session as a warm-up (see below).
• Combine with another activity from the same day (see below).
• Delete (with confirmation).

Combining two recordings of one session

Sometimes one session lands as two activities — you stopped the computer at a long café halt, or your watch died and you restarted it mid-run. When that happens, open either activity and look for the blue "Same session recorded twice?" box. It appears only when there's a matching sibling: same athlete, same sport, starting within about 12 hours of each other (so a morning ride pairs with an evening one, and a session either side of midnight still counts), both imported from a .fit file, and not overlapping in time.

Click Combine into one and the two entries become a single activity that spans the whole session. Fitness (Load) is recalculated across the combined ride, not added up — so a long stop in the middle doesn't inflate it. Any comments carry over, and if one of the originals was matched to a planned workout, the combined activity takes that match.

A few things to know:

• The two originals are replaced by the one combined activity.
• Your original files are kept on the server, so a combine can be undone by support if it ever looks wrong.
• Two recordings that overlap in time (e.g. a watch and a bike computer recording the same ride) aren't combined here — that's a sensor merge, handled by the FIT merge tool.
• Multisport activities (a brick or a triathlon file with swim/bike/run legs) can't be combined — they keep their legs.
• Coaches and premium athletes can combine; free athletes can't.

Marking a warm-up

A race-morning warm-up (a 200 m pool loosener, a few minutes spinning) records as its own activity, and can get mistaken for your actual race leg when the post-race report matches FIT files to swim/bike/run. Tap Mark warm-up on the activity to flag it: it still shows up everywhere as a normal workout, but the race report skips it when picking the leg, so your real effort is the one that counts. Grepiac also auto-suggests the toggle on very short swims. Tap ✓ Warm-up again to un-mark.

Linking to an assessment

If the activity is a test (e.g. 20 min FTP), click Mark as assessment to walk through the assessment form pre-filled from the activity data.
