A 4:59/km pace for the marathon is a strong, demanding effort sustained for three and a half hours. The pace itself is manageable for a fit runner — the challenge is maintaining it through the final 10 km when glycogen stores are depleted and fatigue sets in. This is where months of long runs and tempo work pay off.
A sub-3:30 marathon requires 55–75 km per week with three key sessions: a long run building to 32–35 km (with the final 8–10 km at goal pace), a threshold run of 30–35 minutes at 5:05–5:10/km, and a marathon pace session of 12–16 km at 4:59/km.
Easy runs at 5:50–6:20/km make up the remaining volume. Core strength and hip stability exercises help maintain form when fatigued. Practise your race-day nutrition during every long run — aim for 60g of carbohydrate per hour.
Allow 16 weeks of preparation from a base of at least 40 km per week. The long run is your cornerstone: if you can run 30 km with the last 10 at pace, you're ready. Taper for 3 weeks, reducing volume by 20%, 40%, then 60%.
