Interval training for runners: when and how to start
How interval workouts improve speed and conditioning when they are added at the right dose.
Short answer
Interval training alternates faster running with recovery. Start with a few short repeats, warm up well and keep most weekly running easy.
Intervals are not all-out suffering
The point of intervals is exposure to faster running with enough recovery to maintain quality. Turning everything into continuous suffering misses the point.
A first example is 6 repetitions of 30 seconds fast with 90 seconds easy after a warmup. Finish feeling in control.
Warm up before speed
Run easy or brisk walk for 10 to 15 minutes before faster blocks. Warming up prepares muscles, joints and the cardiovascular system.
After the intervals, cool down for a few minutes instead of stopping abruptly.
Weekly dose matters
For most recreational runners, one interval session per week is enough at first. The rest of the week supports base, technique and recovery.
The question is whether the session improves the plan or just feeds pace anxiety. A smart coach should know the difference.
FAQ
Can beginners do interval training?
