3 milestones
Build a habit of 3+ runs per week over four consecutive weeks, reaching at least 20km total weekly mileage by week 4. Aerobic capacity requires sustained low-intensity volume — this phase cannot be compressed without injury risk. All runs should feel easy enough to hold a conversation.
Proof required
Submit four weeks of GPS-tracked running logs showing 3+ runs per week, with weekly totals reaching at least 20km by week 4. Note your average easy pace and any rest days taken.
What gets checked
- Logs show GPS-tracked data with distance, pace, and route — not self-reported distances
- Sessions vary in length (not identical runs every day), indicating genuine progressive training
- Week 4 weekly total reaches or exceeds 20km across at least 3 individual sessions
