Timing
Trail-Aware Timing Engine
Our timing engine accounts for terrain changes so your splits reflect real trail conditions. Three modes give you flexibility on how to approach your goals — whether you're chasing an FKT or planning a comfortable finish.
Because nobody runs flat on trails
Generic pace calculators assume a flat course. Waldup is designed for trail & ultra running. Our engine models the relationship between terrain and effort, giving you split estimates that account for the long climb to the col and the technical descent on the other side.
Three timing modes
Choose the mode that fits your preparation:
- Target pace or finish time — set a goal and let Waldup calculate splits for every section
- Reference track — use a previous race or training run as the reference
- Fully customisable — override individual section times when you know a climb will be slower or a descent will be fast
Important: All times are indicative. You are solely responsible for assessing your own fitness level, experience, and the terrain and weather conditions on race day.
