FAQ
How should I pace Ultra-Trail Australia UTA100?
Treat the preview as an effort plan, not a fixed road-marathon pace table. The course model includes 4500 m of climbing, so climbs, descents, heat, and aid-station timing matter more than average pace.
How reliable is the current course data?
Headline route data is suitable for preview. Stair-heavy terrain requires segment-level technicality data before high-confidence paid positioning.
