Training foundations

It's wise to follow a training schedule (see above), but whether you're a beginner or seasoned racer, here's a round-up of the key ingredients of training:

  • First, if you're a complete beginner to running, you'd be best off with our BIG Beginners' Index - full of advice and basic get-started programmes.
  • Otherwise, start with the three key sessions of any runner's week.
  • Then, take a look at our basic guide to speedwork (once you're running regularly, this will make the single greatest difference to your race).
  • If you've wisely invested in a heart-rate monitor to control your training effort, our introduction to heart rate training will come in handy.
  • On top of that, 39 great speed sessions, from the simple to the murderous, and...
  • ... race-specific speedwork (not for beginners!)
  • And a guide to doing your weekly long run right.
  • Finally, if you want to see how ordinary runners can move their training to its next level, Hard Training, with Mike Gratton, is a fascinating read.
