Sub 4 Hour Marathon Training Plan
Sub 4 hours is the single most popular marathon goal. It requires a pace of 9:09 per mile for 26.2 miles, which sounds manageable until you realize the distance. This 16 week plan builds your endurance progressively with long runs up to 20 miles, introduces tempo work to raise your threshold, and includes race pace sessions so race day pace feels familiar. Thousands of runners break 4 hours every year. With this plan, you will be one of them.

Key Workouts
20 Mile Long Run
The big one. Run 18 to 20 miles at 10:00 to 10:30/mile. This proves to yourself that you can go the distance. Walk if needed but keep moving.
Race Pace Miles
Mile repeats at 9:09/mile. These make race day pace feel familiar and build pacing discipline.
Tempo Run
20 to 25 minutes at 8:35 to 8:50/mile. Builds speed reserve so race pace feels comfortable.
Long Run with Pace Finish
Run your long run easy for most of it, then the last 3 miles at goal pace. Simulates racing on tired legs.
Common Mistakes to Avoid
Long run too fast
Long runs at 10:00 to 10:30/mile. Going at 9:30 depletes glycogen too fast and increases injury risk.
Going out too fast on race day
Mile 1 at 9:20 to 9:30. Save energy for miles 18 to 26 where the marathon really begins.
Ignoring nutrition during the race
Take a gel every 45 minutes starting at mile 5. Practice this in training long runs.
Not doing the 20 miler
At least one long run of 18 to 20 miles is critical. It builds confidence and trains your fueling strategy.
Running through pain in training
A sore knee or tight IT band in week 10 can end your marathon. Rest early, race healthy.
Race Day Strategy
Miles 1 to 3 at 9:20 to 9:30 (slow start). Miles 4 to 16 at 9:05 to 9:10 (build confidence). Miles 17 to 22 at 9:09 (hold pace). Miles 23 to 26 with everything you have left.
Nutrition Tips
Carb load for 2 to 3 days before. Pre race meal 3 hours out (600 calories, carb heavy). Gel every 45 minutes starting at mile 5. Water at every aid station. Consider salt tabs if it is hot.
Make Every Training Run Count
Marathon training means 20+ mile weeks and long runs that cover massive ground. Your Motera territory map will explode during these 16 weeks. Make every training mile count.

MoteraFrequently Asked Questions
Is sub 4 hours a good marathon time?
Yes. Sub 4 hours puts you faster than about 50% of marathon finishers. It is the most common goal time and a significant achievement.
What pace is a sub 4 hour marathon?
You need to average 9:09 per mile (5:41 per km) for 26.2 miles. That is a steady, sustainable effort.
How far should my longest training run be?
This plan builds to a 20 mile long run. Some runners do 18 miles and that is fine too. You do not need to run 26.2 in training.
How many days a week should I run?
This plan calls for 4 runs per week. Three shorter runs (including one quality session) plus one long run.
Do I need to carb load for a marathon?
Yes. Increasing carbohydrate intake 2 to 3 days before the race helps maximize glycogen stores, which is critical for the last 6 miles.
What if I hit the wall?
The wall (bonking) usually hits around mile 18 to 20. Proper fueling with gels every 45 minutes and not going out too fast are the best prevention.
