Section-by-section times based on the official GPX elevation profile & your settings
🧪 Beta version - the pace model will be refined over time based on real runner feedback. Times are estimates, not guarantees.
How this works: Enter your comfortable flat running pace and pit stop times. The calculator uses the actual Wall Ultra elevation profile to estimate your pace on each section - uphill grades slow you down, downhill grades can speed you up. Toggle whether you walk moderate hills or runnable downhills. Switch to Target mode to work backwards from a finish time.

Official start: 06:00. Some waves start slightly later
Walk moderate hills grade >2% - saves quads
Walk runnable downhills grade <–2.5% - protects knees late in race
Progressive slowdown (30%) pace fades to 70% of target by the finish

Terrain model: Grade adjustments use the official GPX gradient data, smoothed over ~65m intervals (1,657 GPX points). Real stepped escarpment sections (notably Winshields Crag, ~mile 29–32) may be steeper in practice than the GPS average suggests. The wall section between Walltown Quarry (PS2) and The Sill (PS3) should be treated conservatively - it will feel harder than the calculator suggests for many runners. Cut-off times shown are wall-clock times on race day (start 06:00).
