Ever wondered which pace you actually need to run in order to achieve a sub 2h Half-Marathon? Pacr solves that issue for you, simply enter the distance and total time, hit calculate and you will know your 5:41 min/km target pace. Your trainer gave you some cryptic track workout, e.g. 600m at threshold pace of 4:21 min/km, whats that for a actual track lap? With Pacr you can configure your often used distances for which the durations will automatically always be calculated. The workout screen lets you import workouts in json format, and automatically calculates your predefined splits for it. Which makes interval training a breeze.
