At 6:24/km, a 4:30 marathon is a comfortable running pace sustained for a very long time. The pace won't challenge your lungs — it's your legs, joints, and mental resilience that will be tested over four and a half hours. This is a great target for first-time marathoners who have distance running experience.
Run 30–45 km per week with four runs: one long run building to 26–30 km, one session with faster efforts (e.g. 5 × 5 minutes at 6:00/km with 2 minutes easy), and two easy runs at 7:00–7:30/km.
Build the long run very gradually. Walking breaks during long runs are fine — they help you cover the distance while limiting fatigue. As fitness builds, the walking breaks naturally shorten.
Allow 16 weeks and prioritise the long run above everything else. If you can only do one quality session per week, make it the long run. On race day, carry your own nutrition rather than relying on aid stations alone — you'll be running for 4.5 hours and need reliable fuelling.
