Complete a 16km long run as preparation for your first half marathon. Follow a 12-week training plan that builds long runs progressively. 16km is the longest training run most beginner plans include — it gives you the aerobic base to finish 21.1km on race day without bonking.
Proof required
Submit: (1) GPS track showing 16km+ long run completed; (2) note of the training plan you are following.
What gets checked
- GPS shows 16km minimum in a single run — not split across two outings
- Pace is easy/conversational — long runs are not race-effort
- Training plan name or source is mentioned
