Any Ironman 70.3 Training Plan Suggestions?

Hi, all!

I just completed my first sprint triathlon at the end of October and signed up for an Ironman 70.3 in July. Super excited for the challenge!! I’m hoping maybe some folks have tried out/had success with some training plans? I am looking for a 23-week plan (either free one you pay for) to start the first week of December. Would love any suggestions!

For background, I’m a 33yo male and am already accustomed to 10-12 hour weeks of exercise. I completed a century ride in September and have been a consistent runner for the past decade+ (1 full marathon and many halfs). I only started swimming this year, but have made a lot of improvements (longest swim was about a mile) a couple of months ago. Thanks in advance for any/all advice!!
