Interval Runner remembers all workouts, can show them on a map and totals them on a weekly or monthly basis. Interval Runner has eight routines allowing a runner to choose a technique that is the most useful for their current running situation. For example, when training for a short race like a 5K, workouts with Fartlek routine help a runner buildup their speed. Another example, when running long races, the Pyramid routine is useful on the day before the long race for a short shakeout run.

This is a flexible custom interval timer and training scheduler with historical analysis, and you are the only one who has access to your data! As a runner, I’ve had challenges finding a running timer that can manage my more involved interval combinations. Custom Running Intervals allows you to build variable activities with repeatable blocks of intervals. Intervals can be by time or by distance with 3 intensities - walk, steady, and fast. You can repeat your intervals a specific or indefinite number of times, for a defined amount of time, or for a given distance. With an inexpensive upgrade, you can create as many combinations of repeatable sets in the variations you choose, build a training plan on a calendar, see results of past runs, and export results to other apps. Also, your data is only available to you - even I can’t see it. Your data will only exist on your phone, or in your own iCloud storage if you choose. If you save your data to iCloud (by default), you can view the results on any other iPhone or iPad that shares the same iCloud account. Features: 1. Configurable intervals - distance (miles, kilometers), time (hours, minutes, seconds). 2. Configurable repeat blocks of intervals - # of times (or until stopped), distance, time. 3. Clone activities (use an existing activity - repeats and intervals - as a basis to create a similar activity). 4. Apple Watch monitoring and control and heart rate (iPhone app must be started). 5.

Map view to verify GPS location prior to starting run. 13. Map view of running route in results including markers by mile/kilometer and pauses. 14.
