FAQs

Should I train ultras by pace?

Usually not. Use time-on-feet and effort. Terrain changes pace; durability is what transfers.

Do I need back-to-back long sessions?

They can help, but they must be scaled and recovery-aware. One long session + one long hike is a safer option for many.

How do I prepare for cutoffs?

Practice cutoff-safe effort, keep stations efficient, and build margin for terrain and fatigue.
