Your Half Distance | 12-Week Intermediate Performance Plan

If you want to do more than just finish, you need to focus on getting faster through a structured plan. This 12-week program helps you break through plateaus and improve your times in all three sports. By replacing random miles with sessions that have a clear goal, you build the strength to start your race feeling ready. This plan respects your busy life while making sure you are prepared for a performance you can be proud of.

For a front-pack swimmer, the goal is using your technique to gain an early advantage while saving energy for a strong run. We focus on building a solid engine and introducing sessions that challenge your race pace. This 12-week build is designed for athletes who already have a good level of fitness and want to sharpen their performance. Every hour spent training contributes directly to your stamina and race-day confidence.

How This Helps You

• Improved Technique: Swim sessions designed to help you move faster with less wasted energy.


• Personal Pacing: Every workout uses your personal targets so you know exactly how hard to work.
