The aim of interval training is essentially to improve a runner’s speed.
This is achieved by working the body harder than during a steady run, but in short periods, so you can then recover (during a rest period or “interval”) before repeating the process. Amongst other things, the short but harder exertion improves the bloods ability to carry oxygen; the hearts ability to pump blood; and the muscles’ strength and stamina – making us quicker runners!
While ORCs Tuesday night sessions are generally steady paced hour long runs, Thursdays are the preserve of more intense ”interval training”.
A virtually infinite number of workouts can be created by varying the four elements (Distance-Interval-Repetitions-Time) of interval training. A few of the more common types follow.
