FAQ
How should I pace The Canyons Endurance Runs 100M?
Treat the preview as an effort plan, not a fixed road-marathon pace table. The course model includes 5300 m of climbing, so climbs, descents, heat, and aid-station timing matter more than average pace.

Headline race data is seeded. Segment-level canyon heat and climb data should be imported before high-confidence paid positioning.
