Your Half Distance Triathlon 18 Week Race Plan
Welcome to your 80/20 polarised Half Distance Triathlon training plan!
We will use the very latest techniques of polarised training to get you to the finish line in great shape & enjoy your training journey on the way. This plan is 18 weeks with a general phase of 9 weeks, a specific phase of 7 weeks & a 2 week taper.
Polarised training is a model which means you will spend 80% of your time training at a moderate intensity & 20% at a high intensity. Polarised training plans generally outperform other training methods & help prevent injury.
In the specific phase, the weekend swim & bike or bike & run workouts are scheduled on the same day & should be done back to back as a "brick" session to simulate the demands of long distance triathlon racing.
On weekdays during the specific phase, bike & run workouts scheduled on the same day are optional bricks. These sessions are good opportunities to practice pacing & nutrition & to test out race equipment so that these things are familiar on race day. There is an optional Sprint or Olympic Distance practice race or race simulation in week 15.
In the general phase there are sessions in HR Zone 3 & above to develop speed, muscular endurance & aerobic capacity.
This plan is for first time half distance athletes & even first time triathletes and enable you to finish strong at your event. You should be able to swim & run comfortably for 45 minutes & cycle for 60 minutes & complete at least 3 hours of aerobic exercise over seven days.
The weekly training load starts at 4 hours in week 1 & peaks at 10 hours in week 16.
What do you get in the plan:
- 18 weeks of swim, bike, run and S&C sessions (HR & Power)
