For more detailed information, please visit the FAQ. The specific course profile, course elevation, and the typical race time wet bulb temperature and ambient temperature data for each marathon is then used to determine how one would expect to perform at one marathon compared to another under these conditions. The assumption is that your speed as a fraction of the world record is a constant that is the same for every distance. The Marathon Time Conversion tool utilizes an algorithm derived from research on how grade, elevation, and wet bulb temperature and ambient temperature affect marathon running performance. This form tells you what running times you should expect on different distances if you were to train specifically for those distances. For example, use this tool to see how much faster or slower you would expect to run if the weather was normal for race day and run on the current year's course. This tool compares marathons and converts times using data for what you would expect on a typical race day. Or, just have fun - this is one of our favorite calculators. Use this as you get older to compare your times to your earlier PRs and/or use these to create a handicap for an older friend or relative. Custom Race Map & Elevation Profile Service This calculator can help you determine the age and sex equivalent times for your time.Request a Race be Added to the Pace Band Page.Request a Marathon be Added to the Marathon Time Converter Tool.Faster Running: Craig's Running Calculator (also training paces).Using Riegel's formula t 2 = t 1 × (d 2 / d 1) 1.06: In road running the appeal is not always just to run a precise distance, but also to do this in a prescribed time. Running Calculator (also training paces, altitude and temperature effects) The running pace per kilometre in practice. Running pace calculator, training plans, and coaching by renowned running coach, Greg McMillan. Runworks: Running Calculator (also training paces, altitude and temperature effects).Some of the many other race performance predictors Nevertheless, the method is reasonable and easy to understand. It's also not clear if the curve obtained from world records applies to amateurs without any change. Keep in mind, this is only an estimate, and optimal performance at any distance depends upon a variety of factors, including a training program specific to that distance. Smaller features in the graph might be noise that could be smoothed out. Based on your time for a given running distance, this calculator estimates the equivalent performances at other distances. The author has over 10 years of running experience including track, road, and trail running. The peak between 400m and 800m is explained by the transition from sprint to middle-distance which requires the runner to tap from a different energy source. Compute pace and time according to elevation gain, altitude and temperature. The graph below derives b experimentally using world records. Need some help Event Time Announcer Show local times worldwide for your event. To specify noon (middle of day), select 12 / 12 pm in the Hour-field and 00 in the Minutes field. Your running pace will be 360 seconds per kilometer (3600 sec/10 km 360 sec/km), and your speed will be 10 kilometers per hour (10 km/1 h 10 km/h). To specify midnight (start of day), select 00 / 12 am in the Hour-field and 00 in the Minutes field. Enter the time it took you to run that distance, in hh:mm:ss format after. Peter Riegel proposed using the constant b=1.06. kilometers) Example running pace calculation Imagine that you take precisely an hour to run 10 kilometers. Select the units for the distance you ran, either kilometers or miles. To make a marathon in under 4 hours, you need an average pace of 5.69 min per km (5 minutes and 41 seconds). The next value, your required pace, is what probably interests you the most.

Your speed as a fraction of the world record:Ī simple formula to predict performance is t 2 = t 1 × (d 2 / d 1) b where b can depend on the distance or other factors. Our marathon time calculator will automatically display the speed you need to achieve such a result 10.55 km/h.
