✨ Why this workflow?

Stop manually reviewing your training history. This workflow automates the entire analysis: collecting activities, filtering by date range, comparing progress, generating a structured AI report, storing it, and emailing it to you.

Battle-tested: refined across multiple Strava accounts to ensure strong error handling and stable performance. Fully documented: each block is cleanly structured; logic is easy to follow. Safe & robust: handles missing fields, invalid dates, empty ranges, and malformed inputs. Flexible: change the analysis period (week/month/year/total), language, and recipient in one single node (OPTIONS). Zero manual work: reports arrive automatically.

🧠 What does the workflow do?

Reads your entire Strava activity dataset from Google Sheets. Filters activities by your chosen range (last week, last month, last year, or all time). Formats each activity as “Activity 1, Activity 2, …” (from newest to oldest). Sends the full historical dataset + the previous AI report (if available) to GPT-5-nano. Generates a complete performance report with six sections:
