12 Week Advanced Half Distance Plan: Built for Progress

Many advanced plans are boring because they rely on repetitive volume that leads to performance plateaus. This 12 week program is different. We included a variety of sessions to keep you engaged while focusing on the high level precision needed to race at the front of the pack. It is for the experienced athlete who already has a strong swim and wants a training schedule to match that competitive drive. This blueprint replaces junk miles with science based sessions that have a clear purpose, ensuring you arrive at the start line sharp and ready to lead.

How You Will Succeed

• Better Efficiency: Refine your movement across all three disciplines so you can apply your full strength from start to finish.


• Personalized Pacing: Every session uses your personal targets so you know exactly how hard to work. You will stop guessing how fast you should go.


• Energy Control: Learn to manage your effort on the bike so you still have strong, capable legs for a high performance half marathon finish.

The Science of Your Progress

• Sustained Speed: Targeted intervals help you hold a faster pace for longer periods without fading.


• Saving Energy: Improve how your body uses fuel during the bike leg so you do not hit the wall during the run finish.


• Better Technique: Simple focus points help you swim faster and run with improved form. All swim sessions are written by a professional swim coach.


• Aerobic Ceiling: High intensity sessions increase your top speed, making your target race pace feel much more manageable.

Your 12 Week Roadmap

• Weeks 1 to 4: Foundation. Establish benchmarks and build the base stamina needed for higher intensity work.


• Weeks 5 to 8: Specificity. Shift to volume at intensity, simulating the exact metabolic demands of your race.


• Weeks 9 to 12: Peak and Taper. Reduce volume while keeping quality high so your systems are primed for maximum performance.

This Plan Is For You If:

• Front Pack Swimmer: You expect to exit the water in the front third and want a professional plan to maintain that lead.


• PB Chaser: You want a professional schedule designed to help you break your personal records.


• Experienced Competitor: You are ready for a structured plan that values quality and variety over just doing more miles.
