Elevation Pace Adjuster: What Hills Do to Your Finish Time
A flat pace flatters a hilly course. This adjuster adds a simple climbing cost so a hilly goal pace stays honest.
What is the Elevation Pace Adjuster?
Enter your flat pace in minutes per kilometre, the course distance, and its total climb. The tool adds an estimated time cost for climbing and shows the adjusted pace. This is a rough estimate: gradient, descents, and surface change the real cost of hills.
How to use it
- Enter your flat pace in minutes per kilometre.
- Enter the course distance and total climb.
- Click Adjust My Pace.
Worked example
A 5 min/km pace over 21.1 km is 105.5 minutes flat; adding 300 metres of climb at an estimated 0.006 minutes per metre adds 1.8 minutes, for about 107.3 minutes.
How much does 300 m of climb add to a half marathon?
About 1.8 minutes on this rough model, moving a 105.5-minute flat finish to about 107.3 minutes.
Frequently asked questions
Is the climbing cost exact?
No. It is a rough rule of thumb; steep pitches and technical descents change it.
Do descents give time back?
Partly, but not fully: most runners lose more on climbs than they regain descending.
