12 Week Endurance All-Round (run base)

Aidan King

12 Weeks

Training Plan Sample Week

Plan Description

Looking to improve all-round endurance and fitness in running? Looking to incorporate some strength sessions to enhance your running?

This is my 12-week all-inclusive training plan, based on 6 years of being an endurance athlete and enthusiast. Including the key leg, core and all-round s&c sessions that I know work to increase run performance.

This exact programme has been used to get top 100 at Great West Run, sub 19 min 5k, GB Duathlon World Champs qualification and multiple marathon results for clients.

If it isn't broken, don't fix it - and that is why I am sharing this training plan with you - BECAUSE IT WORKS!
