Your 19 Week Olympic Distance Duathlon Plan from a Level 3 British Triathlon Coach
Welcome to your training plan!
This 19-week training plan is for duathletes who have a specfic goal of walking up the podium steps and being the best in their age group.
Chose this plan if you have a few triathlons under your belt of have a strong history in the two discipline.
A pre-requisite would be that you can comfortably bike and run for 90 minutes. You should be comfortable with 6 hours of aerobic exercise over a week.
The weekly volume starts a 9.5 hours in week 1 and peaks in week 13 at 13 hours.
You should consult your doctor before embarking on any physical fitness training.
The training sessions can be completed in a number of locations. The bike sessions could be done either outdoors or indoors, the same goes for the running sessions. Ideally some of the running session should be done on a 400m track. We would strongly advise that you do spend as much time as possible training outdoors so that you get time training in similar conditions to those that you will be racing in.
I have set Monday as your rest day which will enable you to recover from the longer sessions at the weekend.
The first 14 weeks is your general preparation phase
Weeks 15 to 17 are the Race Specific Phase
Weeks 18 and 19 are your Taper Phase
The Plan Includes:
🏊 🚴♂️ 🏃 🧱 Bike, Run & Transition/Brick Sessions
🏋️ Strength & Conditioning session to help prevent injuries (from a NASM Personal Trainer)
⌚ Bike sessions include Power structured files for Zwift, TrainingPeaks Virtual, Wahoo, Rouvy, Garmin, Coros, Polar etc
