Elevation Adjusted Pace Calculator
Estimate grade adjusted pace, moving time, finish time, climb cost, descent effect, altitude slowdown, and training load from a hilly run or race route.
📌Descriptive Presets
Presets load realistic route profiles so you can compare flat fitness pace with elevation adjusted pace for climbs, descents, altitude, footing, and stops.

💡Tips
Running on hills require a different amount of energy then running on flat terrain. The pace that a runner maintain while running on a hill may be slower than an individual’s normal running pace, but that slower pace dont indicate that they are exerting less energy during those runs. Individuals must exert more energy when running on hills due to a force of gravity.
Concepts like grade adjusted pace allows an individual to understand if they are overexerting themselves when running on hills, or if they have enough energy remaining to continue running on flat terrain after those hills. To utilize the grade-adjusted pace calculator, the individual must first note their flat fitness running pace. This flat fitness pace is the most important measurement for the calculator.
How Hills, Terrain, Altitude and Carried Weight Affect Your Running Pace
For distance races, individuals should use a pace that matches the distance that they intend to run, and should avoid using a sprinting pace for distance races, as this will create inaccurate estimates of running time for those races. The individual will get an accurate projected time to finish the race if they enter the distance that they intend to run in the calculator. In addition to the grade of the hills that is to be run, the type of terrain that the individual will encounter will impact the energy that they use during those runs.
For instance, an individual will use less energy when running on paved roads than when running on muddy trails. The calculator allows for an individual to account for these difference in terrain. Individual may think that descending hills will allow them to use less energy than ascending hills, but if the descent is too steep or rocky, they may use more energy to descend than they would travel on flat terrain.
Therefore, the grade-adjusted pace calculator can help an individual to avoid overexerting themselves when descending hills. Another factor that may impact the energy that an individual use during a run is the altitude at which they are running. If the individual is running at an altitude of 5,000 feet or higher, the thinner air will require their aerobic system to work harder in order to provide oxygen to their muscles.
The effect that altitude has upon an individual’s aerobic system is independent of the grade of the hills. By incorporating the altitude into the grade-adjusted pace calculator, individuals can determine whether the slowdown in their pace is the result of the grade of the hills or the thin air at which they are running. An individual’s carried load while running can also impact the energy that they use while climbing hills.
Any items that are contained within a runner’s load, such as hydration vest or food gels, will increase the amount of energy required to climb hills due to the effect of gravity upon those items. The load that the individual enters into the calculator is based off the percentage of the individual’s body weight that the item is, as a given load will impact a lighter runner more than it will impact a heavier runner. Although it may seem like a small amount of energy, the energy that is required to carry items impacts the energy that an individual will use when competing in ultramarathon races.
These reference tables will help to provide an individual with mental cue to compensate for the physical factors described above. For instance, if the grade of the hill is 10% or greater, it may be more efficient for the individual to power hike the hill instead of attempting to run the distance. A power hike is a method of descending hills (or ascending them) by stepping heavy on the foot that is to descend (or ascend), and is a tactic that an individual can use to conserve their energy for later in their run.
These tools will help an individual to manage their expectations of their performance during races with hills, and to avoid burnout. If the individual knows that a specific hill will impact their finish time, they can adjust their pacing to accommodate the hill. If they attempt to sprint up the hill, they may end up crashing their body much more later in their run.
Additionally, an individual should review their performance with these tools after their run to ensure that their energy levels and their exertion of effort during the race match the demand of the hills that they had to race against.
