How can I prepare for an Ironman 70.3 in 6 months?

I ve been training consistently for a while now and I’m looking to specifically work on preparing for my first Ironman 70.3 in 6 months (finishing it in less than 5 hours). I know I need to balance swim, bike, and run training, but I’m not sure about the best approach

What worked for you? Should I be doing brick workouts frequently or focus on building each discipline separately first? How should I balance volume vs intensity? Should I do two workouts per day or keep it to one longer session knowing that i have a full time job? Any specific training plans you’d recommend?

I saw a 6 months Ironman 70.3 training plan mentioned in another thread here https://besttriathletes.com/half-ironman-70-3-training-plan/, and I m curious if anyone has tested it out and seen results

Would love to hear what s helped you build the endurance and strength for all three disciplines. Thanks guys
