Frequently Asked Questions
What is a good marathon time?
Average finish is about 4:30. Sub-4:00 is solid, sub-3:30 is competitive, sub-3:00 is elite amateur, and sub-2:30 is professional territory.
Should I run even splits?
Yes — running the same pace throughout is the most efficient strategy. Negative splits (faster second half) are even better but harder to execute.
How do I train for my goal pace?
Long runs at 30-60 seconds slower than goal pace. Tempo runs at goal pace. Speed work at faster than goal pace. Build up to 18-20 mile long runs.
What about the wall at mile 20?
The wall happens when glycogen stores deplete. Prevent it with proper nutrition (carb loading, race-day fueling with gels every 45 min) and adequate training.
