route Race Day Split Logic
restaurant Fueling for Sub-4:00
Night Before & Race Morning
- • Carb-heavy dinner (pasta, rice).
- • Morning: oatmeal with banana, toast, 500ml water, coffee if normal.
- • 3 hours before start.
During Race Gel Schedule
- • Gel 1 at 45min, Gel 2 at 1:30, Gel 3 at 2:15, Gel 4 at 3:00, optional Gel 5 at 3:30.
- • Water at every station.
warning Critical Pitfalls to Avoid
Going Out Too Fast
A 1:52 first half feels amazing until you're walking at 35km. Target 1:57-1:58 at halfway.
The Wall (30-35km)
Glycogen depletes here. Prevention: conservative pacing, consistent fueling, mental preparation. If it hits: slow down but keep moving.
Skipping Nutrition Practice
Your stomach needs training too. Practice exact race-day fueling from Week 8 onwards.
After the Sub-4:00
Consolidate
Run another sub-4 to lock it in and build marathon experience.
Get Faster
Target sub-3:30 or even sub-3:00 marathon.
New Challenge
Try an ultra marathon or different distance entirely.
