A 16 week training plan to prepare you for a 50k to 90k ultra marathon. Each week has a particular focus and the overall plan is split into four 4 week blocks.
This plan assumes a basic level of fitness and a minimum level of running specific training, if not then a bespoke targeted plan may be more suitable.
One of the prime foundations is the principle of consistency each day, each week and each month. This can include daily checks on your health and wellness, introducing active recovery sessions, establishing a strength training routine that can be completed week in week out.
Every week will include a variety of training sessions with the objective to help your body adapt in order to prepare for the event, some weeks will include a higher number of runs, others higher intensity, some wil include back to back or double day runs. Every variation is designed to help stimulate and improve your endurance habit so you are ready for race day.

The Endurance Habit - We are what we repeatedly do. Excellence, then, is not an act, but a habit. Doing the right things on a regular basis, without a pause for thought, so they become a way of life.

Heavily involved in coaching cycling at youth and U23 level as well as developing my passion for ultra running.
