Things to consider

  • Please do a 15-minute warm-up and cool-down before threshold, continuous or hills or interval sessions.

  • If you’re feeling up to it, you may wish to consider a 20–30 minute recovery run in the morning before any of the quality sessions.

  • Always substitute cross-training for running if you are injured, very sore or it’s not safe to run.

  • Please add core conditioning, Pilates or yoga classes once or twice a week if you have time.

  • Try to stretch every day for at least 10 minutes.

  • Always eat within 20–30 minutes of finishing a run.

  • Always train at the specified paces; don’t compromise or run too hard. Tiredness always catches up, so take extra rest if required.
