Work for AMBIT1 With sound and light. High intensity interval running inspired by coaching methods used by Peter Coe when coaching his son, olympic champion and 800m world record holder of Sebastian Coe. This interval running App guides you through an interval session starting with 15 min warmup, then 10 x 200m interval running exercise with 30 second recovery between intervals. The hard intervals are supposed to be high intensity, i.e. very hard. The recovery should be made walking. The App will show meters left during the interval and seconds left during recovery.
