+# Activity Reprocessing Implementation
+
+## Goal
+Add capability to reprocess existing activities to calculate missing metrics like `avg_power`
+
+## Requirements
+- Reprocess all existing activities
+- Add web UI button to trigger reprocessing
+- Background processing for large jobs
+- Progress tracking and status reporting
+
+## Implementation Phases
+
+### Phase 1: Database & Infrastructure
+- [ ] Add `reprocessed` column to activities table
+- [ ] Create migration script for new column
+- [ ] Update activity parser to handle reprocessing
+- [ ] Add CLI commands for reprocessing
+
+### Phase 2: CLI & Backend
+- [ ] Implement `garminsync reprocess` commands:
+  - `--all`: Reprocess all activities
+  - `--missing`: Reprocess activities missing metrics
+  - `--activity-id`: Reprocess specific activity
+- [ ] Add daemon support for reprocessing
+- [ ] Create background job system
+
+### Phase 3: Web UI Integration
+- [ ] Add "Reprocess" button to activities page
+- [ ] Create API endpoints:
+  - POST /api/activities/reprocess
+  - POST /api/activities/{id}/reprocess
+- [ ] Implement progress indicators
+- [ ] Add real-time status updates via websockets
+
+### Phase 4: Testing & Optimization
+- [ ] Write tests for reprocessing functionality
+- [ ] Add pagination for large reprocessing jobs
+- [ ] Implement caching for reprocessed activities
+- [ ] Performance benchmarks
