List activities in a date window

GET/v1/athletes/{athlete_id}/activitiesrequires activities.read

Activities in a date window, completed and planned. The window may reach into the future: past sessions are matched on when they started, future ones on when they are planned for, so one call covers both sides of today.

Defaults to the last 30 days plus the next 14. Summaries only - call GET /v1/activities/{activity_id} for the analysis of one session.

Path parameters

athlete_idstringrequired
The athlete to act on. `me` is the athlete who authorized this token; any other ID must be an athlete they coach.

Query parameters

startstring
Start of the window, as RFC 3339 or YYYY-MM-DD. May be in the future.
e.g. 2026-08-01
endstring
End of the window, as RFC 3339 or YYYY-MM-DD. May be in the future, to include planned sessions.
e.g. 2026-09-01

Example

bash

curl -X GET "https://api.stride.is/v1/athletes/{athlete_id}/activities" \

Errors

Every error is an RFC 9457 problem document. Branch on its code, which is stable; detail is prose and may be reworded.

400The request was malformed: an unparseable date, an unknown enum value, or a parameter combination that cannot be satisfied.
401No access token was supplied, or it is not valid for this API.
402The Stride account the token belongs to has no active subscription or trial.
403The token does not hold the scope this endpoint requires, or may not act on the athlete or team named.
404No such resource, or it is not visible to this token. The two are deliberately indistinguishable.
405The path exists but does not serve this method. The Allow header lists the ones it does.
429A rate limit was exceeded. Retry after the period in the Retry-After header.
500Something failed on Stride's side. The failure is logged with a trace ID.
