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 an athlete with developing swim technique, the goal is saving energy for the bike and run. We focus on building a solid engine before introducing sessions that challenge your race pace. This 12-week build gives your body time to get used to the work, helping you improve without the risk of overtraining. Every hour spent training contributes directly to your stamina and race-day confidence.
