Your Half Distance | 12-Week Intermediate 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 mid-pack swimmer, the goal is refining your technique to save energy for the bike and 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 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.
- Energy Control: Guidance to help you manage bike effort for a strong half marathon finish.
- Build Strength: Sessions to help you stay powerful and avoid injuries as training load increases.
Your 12-Week Roadmap
- Weeks 1-4: Stamina. Set your targets and build the fitness needed for the harder work.
- Weeks 5-8: Progress. Increase training time and improve your skills in the water and on land.
- Weeks 9-12: Readiness. A taper to help you recover so you feel fresh and fast on race morning.
