If you're an experienced runner, looking to improve your 10K time and run a 35-45 minute 10K, we've got the plan to help. It involves four weeks of training, running 6-7 days per week. It will be a mixture of tempo, speed and fartlek runs.

Two key things to remember before starting the training plan:

1. The sessions aren’t set in stone. Be flexible with speeds and distances where you need to, especially if you start to feel tired.

2. Feel free to change the order of the sessions to fit in with your life. If you are mixing changing sessions around, follow the basic principle of not scheduling too hard sessions back-to-back.
