Dream of taking on the challenge of an Ironman Triathlon? Or a seasoned athlete looking to be even fitter for summer 2018?

Building base fitness is vital.

Without it, the 8 + hour race-specific sessions you need to complete in order to take on an Ironman can be far too much. Many amateurs fall short due to injury or fatigue before the start line. 

This plan can help you build fitness through time efficient, tried and tested programming.

  • Download or view the plan through an easy to use professional training software, Training tilt.
  • View the plan on your desktop or using the Training tilt mobile App.
  • Test your fitness at the start, during the program and at the end to track your fitness progress over the 10 weeks.
  • Pay just under 60p for every hour of the plan!

 Ironman races aren't complete without the athlete having a strong base of fitness. Whether it's your first time building a base or you want to increase your base fitness to achieve a PB season, this plan can help you.


Toms training plans are simple, effective and most importantly to me adaptable around my work. I've used TWF training plans for 3 years running and I get better every year.

I used one of Toms plans after a deflating IM Wales 2016. I felt that I had trained hard, been consistent and had gone out and trained a lot in the months leading up, I wanted to know where I was going wrong! With some solid advice and a structured plan I was able to take over 45 Minutes off my IM PB.
