Key Points

Long‑run focus: Week 5 of a marathon plan, 29 km (18 mi) total distance.
Marathon‑pace segment: 11 km run at target marathon pace (~4:27 min/km or ~7:10 min/mi).
Structure: 16 km easy (≈5:30‑5:45 min/km), then the 11 km MP block on flat Battersea Park, followed by a short cool‑down.
Practical tips:
- Run the MP portion on a flat loop to lock in pacing.
- Take a gel and sip water around the 7‑8 km mark and again before the MP block.
- If the pace feels too fast, drop back to ~4:33 min/km and focus on steady effort.
- Listen to cumulative fatigue; adjust nutrition and hydration accordingly.
