16 Week Intermediate Half Distance Plan: Built for Progress

Many intermediate plans rely on repetitive volume that fails to challenge your fitness. This 16 week program is for the balanced athlete whose swimming ability matches their cycling and running performance. We included a variety of sessions to keep you engaged while targeting improvements across all three disciplines equally. This plan replaces junk miles with science based training that has a clear purpose, ensuring you arrive at the start line sharp and ready to race.

How You Will Succeed

• Balanced Improvement: Develop your swim, bike, and run speed at a consistent rate for a well-rounded race day performance.


• Personalized Pacing: Every session uses your personal targets so you know exactly how hard to work. No more guessing.


• Energy Control: Learn to manage your effort on the bike so you have the strength to finish the half marathon with a powerful run.

The Science of Your Progress

• Sustained Speed: Targeted intervals help you hold a faster pace for longer periods without your form breaking down.


• 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 move through the water faster and run with improved mechanics. Written by a professional coach.


• Aerobic Capacity: Diverse sessions increase your top speed, making your target race pace feel significantly easier.

Your 16 Week Roadmap

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


• Weeks 5 to 8: Adaptation. Safely increase your training volume as your body adapts to the workload.


• Weeks 9 to 12: Specificity. Shift to sessions that mimic the exact effort and speed you will need on race morning.


• Weeks 13 to 16: Peak. Reduce training volume while keeping quality high so you feel powerful on race morning.
