How to Train for a Marathon

The marathon (42.2km / 26.2 miles) is the classic endurance challenge. A solid training plan takes 16-20 weeks and builds to 55-80km per week depending on your goals. The marathon rewards consistency and patience more than any other distance.

The 80/20 Rule

80% of your running should be easy (Zone 1-2). Only 20% should be hard (tempo, intervals, race pace). Most marathon failures come from training too hard, not too little.

The Long Run

Your weekly long run builds from 16km to 32-35km. Increase by 2-3km per week, with a cutback week every 4th week. Practice your race-day nutrition during long runs.

Marathon-Specific Work

Start adding marathon pace segments to long runs at week 10+. Example: 25km total with the last 10km at marathon pace. This teaches your body to run fast on tired legs.

Fueling

You'll need to consume 30-60g of carbs per hour during the race. Practice with gels, chews, or real food during training. Your stomach needs training too.

Frequently Asked Questions

How long does it take to train for a marathon?

16-20 weeks for experienced runners. 24+ weeks if it's your first. You should be comfortably running 30-40km per week before starting a marathon plan.

What's a good first marathon time?

Finishing is the goal. Average first marathon time is 4:30-5:00 for men and 5:00-5:30 for women. Anything under those is great for a first attempt.

Should I run the full 42km in training?

No. Most plans peak at 32-35km. Running the full distance in training creates injury risk without meaningful fitness gains. The race-day adrenaline covers the last 10km.
