Plan Description

Middle Distance Beginner/Intermediate Triathlon Training Plan

If you want to race Middle Distance triathlon check out the 20-week Middle Distance Beginner to Intermediate Triathlon Training Plan from WhittleFit.

Who's it for?
This triathlon training plan is aimed at triathletes who may have trained for a couple of seasons and completed shorter events, or are new to triathlon but have some previous swim, bike and run experience. The aim is to help you to achieve your goal with a clearly structured 20-week plan which avoids over-training and injury, whilst progressing with just the right balance of challenging and achievable training.

Is it for you?
If you’re looking for a training plan designed by specialist triathlon coaches who have raced triathlon events all over the globe, and you don’t need a coach to hold your hand, then this is the training plan for you!

What's involved?
Because this plan is aimed at beginner athletes, it progresses very gradually over the 20-weeks to ensure you achieve your goal without injury or over-training, by building progressively, starting with a combination of shorter swims, rides and runs, building towards a peak week of just over 11 hours of training.

Why choose our plan?
The coaches at WhittleFit have raced at Iron distance events all over the globe, therefore we’re very well placed to advise on the training requirements to have a great race.
