It’s simple. Enter a recent best effort in the pace calculator to find your pace or time. The "predict" pivot will give you projected finishing times for other, common race distances. The "prepare" pivot gives you the correct training paces for easy runs, long runs, and various kinds of speed training. A quick tap lets you schedule a workout in your calendar, complete with notes on warmup, target pace, and any rest intervals. Easily share complete race time and pace predictions, as well as training paces. It’s advanced. More experienced runners and coaches will appreciate unique features like our customizable splits. (Yes, like you, I remember running repeats on a crazy, non-standard, indoor track.) Runners competing in extreme conditions can use the "perform" pivot to fine tune pace and time based on race-day weather and course conditions. (Alternately, you can normalize a time from a performance in difficult conditions.) Power users can also tweak the settings page to customize the application’s calculations to reflect their individual fitness in several categories such as acclimatization to heat and altitude, strength on trails, on climbs, and more. Only Run Ranger gives you all this in one simple, easy-to-use package. No other running app or online site comes close. They can’t, because most of Run Ranger’s advanced calculations are based on original research incorporating tens of thousands of real-world running performances. Finally, Run Ranger is the only running app that lets you customize the numbers behind the calculations by using our simple but powerful settings page. NEW • Customizable splits • Boston Marathon helper • We have completely redesigned the settings page in order to give the most accurate race predictions and training paces. Please review your settings to get the most accurate calculations as well as to enable age-adjustment and Boston Marathon helper.
