Key Workouts

The 20 Mile Long Run

The longest run of your training. Go slow (1 to 2 min slower than goal race pace). Practice your exact nutrition plan. Walk if needed. This run builds mental toughness.

Purpose: Distance confidence and nutrition practice

Easy Runs

Short, comfortable runs of 30 to 40 minutes at an easy, conversational pace. These make up the bulk of your training.

Purpose: Aerobic base and recovery

Tempo Run

20 minutes at a brisk but controlled pace. Not all out, just comfortably hard. Builds fitness without the injury risk of intervals.

Purpose: Aerobic efficiency

Common Mistakes to Avoid

Starting the race too fast

Run the first 5 miles at least 30 seconds per mile SLOWER than your goal pace. The excitement will trick you. Do not fall for it.

Not practicing nutrition

Practice eating gels, chews, or whatever you plan to use during every long run over 90 minutes. Your stomach needs training too.

Wearing new shoes or clothes on race day

Nothing new on race day. Wear only gear you have trained in. New shoes = blisters.

Panicking at the wall

Miles 18 to 22 will be hard. You might want to quit. This is normal. Walk if needed. Eat a gel. Keep moving forward.

Comparing yourself to other runners

Run YOUR race at YOUR pace. Someone else going faster does not mean you are going too slow.

Race Day Strategy

Miles 1 to 5: slow and patient, soak in the atmosphere. Miles 6 to 13: settle into your groove, eat every 45 minutes. Miles 14 to 20: the work begins, focus on one mile at a time. Miles 21 to 26: grit, determination, and the crowd will carry you home.

Nutrition Tips

Carb load for 2 to 3 days before (extra pasta, rice, bread). Pre race meal 3 hours before (nothing new). Gel every 45 minutes from mile 5. Water at every single aid station. Do NOT skip stations.
