Half-Ironman in April 2022 (30 weeks left) – should I repeat 18 weeks plan?

Hi all!

I’m a beginner triathlete – although I have done 3 70.3s already, I am basically bad at all 3 sports. That doesn’t take away from my enthusiasm though, and I am always thinking about how I can improve in any of the disciplines.

My A event (and my only event for now), is a Ironman 70.3 in April 2022, about 30 weeks away. I’ve just bought and started my 18 weeks Ironman 70.3 Level 1 plan, but realizing that I’m going to end it 12 weeks before the event… I am left wondering what I should do.

There likely won’t be any events before my 70.3, so I can’t / don’t want insert any race.

A few of the options I thought of:

1) Stop the 18-week plan – maybe focus on 1 or 2 sports over the next 12 weeks, and then start the 18 weeks plan, well, 18 weeks before the race. I would really like to improve on all 3 sports though, but question is if I wouldn’t benefit more from focusing on say cycling or running first.

2) Stretch the current plan – repeat some of the initial weeks i.e. Week 1, week 1, week 2, week2, week 3, week 3, etc.. I would not be looking forward though to moving all the workouts manually in Trainingpeaks to make this work.

3) Complete the 18 weeks, start a 12 weeks plan thereafter (or alternatively, re-start the last 12 weeks of the 18 weeks plan)

I am curious as to what this group thinks what are some pros/cons. Clearly it’s highly individual and depending on what/how I set my priorities, but I’m really torn and maybe not entirely clear what all considerations are.

Thanks much in advance!
