12 Week Advanced Half Distance Plan: Built for Progress

Most advanced plans are boring because they rely on repetitive volume that leads to plateaus. This 12 week program is different. It is designed for the athlete who is already a strong runner and cyclist but needs their swimming to match that level. We included a huge variety of sessions to keep you engaged while helping you move through the water more easily. This plan replaces generic training with science based sessions that have a clear purpose, ensuring you arrive at the start line ready to race rather than just survive.

How You Will Succeed

• Better Efficiency: Focus on moving through the water with less effort so you have more energy left for the bike and run segments.


• 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 how to manage your effort on the bike so you still have strong, capable legs for the half marathon finish.

The Science of Your Progress

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


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


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


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

Your 12 Week Roadmap

• Weeks 1 to 4: Building the Base. Set your benchmarks and start building the stamina you need for race day.


• Weeks 5 to 8: Specific Training. The focus shifts to sessions that mimic the exact effort you will need on race morning.


• Weeks 9 to 12: Peak and Taper. Reduce your training volume while keeping the quality high so you feel powerful on race day.

This Plan Is For You If:

• Land Strong Athlete: You are a good cyclist and runner but want your swimming to be just as effective as your land based disciplines.


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


• Mid-Pack Swimmer: You expect to exit the water in the middle third and want a plan written by a pro coach to maintain that edge.
