psychology The 4 Pillars of Ultra Running
Forget Pace
You're not running 5:30/km. You're running "easy enough to sustain for 7 hours."
Walk the Hills
Power hiking uphills is faster and more efficient than running them slowly.
Eat Constantly
You can't store enough glycogen. You must consume 200-300 calories per hour.
Stay Positive
Low points will come around 30-40 km. They will pass. Keep moving.

Conversational pace—can speak in full sentences.
Extended run measured in hours, not kilometers.
Long runs on consecutive days—simulates race fatigue.
Run with elevation gain—practice power hiking.

mindfulness The Bad Patch (30-40 km)
warning Critical Pitfalls to Avoid
Starting Too Fast
The first 10K should feel embarrassingly easy. If you're running with the pack, you're probably going too fast.
Waiting to Eat
By the time you feel hungry, it's too late. Eat on a schedule every 30 minutes from the start.
Skipping Walk Breaks
Walking uphills early saves your legs for the final 15K. Don't let ego cost you the finish.
New Gear on Race Day
Never race in shoes, vest, or nutrition you haven't tested extensively in training.
After Your First 50K
Recover & Reflect
Take 2-4 weeks easy. Let your body adapt to what you've accomplished.
Another 50K
Different terrain, faster time, or just for fun.
