About the Marathon
The marathon (26.2 miles) is the ultimate challenge for many runners. Preparation typically requires 12 to 16 weeks with 4 to 5 sessions per week, including progressive long runs up to 30-35 km (20-22 miles).
Race strategy is crucial: the negative split (second half faster than the first) is the most effective approach. Start 10-15 seconds/km slower than your target pace for the first 10 kilometers, then gradually build speed.
Frequently Asked Questions
What pace for a 4-hour marathon?
For a 4-hour marathon, maintain a pace of 5:41 min/km (9:09 min/mile), which is 10.55 km/h. Plan to pass the half around 1:58-2:00 to give yourself margin.
How to avoid hitting the wall?
The wall (around mile 20/km 30) happens when glycogen stores are depleted. To avoid it: start conservatively, hydrate regularly, take gels every 30-45 minutes, and include long runs (30-35 km) in your training plan.
