Plan Description


Half Marathon | 12-Week Advanced Performance Plan


For an experienced runner, finding more speed requires moving beyond simple weekly miles. This 12-week program provides the professional structure needed to break through performance plateaus and achieve a personal best. By replacing unstructured running with sessions that have a clear goal, you build the stamina to hold your target pace. This plan respects your busy life while ensuring you are prepared for a result you can be proud of.


Success at this level is about precision. We focus on your ability to maintain pace through purposeful, high-quality sessions that challenge your limits. This 12-week build allows for the technical refinement needed to perform at your potential. This plan removes training uncertainty, letting you focus on the work while balancing a busy job. Every session improves your speed and durability, ensuring you arrive at the start line ready.

How This Helps You



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

  • Technique: Specific focus points help you move with less effort and stay strong late in the race.

  • Energy Control: Learn to manage effort so you have the stamina for a fast final few miles.

  • No Guesswork: Every session tells you exactly what to do, letting you focus on execution.

Your 12-Week Roadmap



  • Block 1: Foundation. Set your benchmarks and build the base stamina needed for harder work.

  • Block 2: Development. Shift toward sessions that help you hold your target race pace under pressure.

  • Block 3: Readiness. Fine-tune your race speed and follow a taper to ensure you feel powerful.

Is This Your Next Step?



  • Experienced Runners: You can run for 90 minutes and want to improve speed over the 21.1km distance.

  • PB Chasers: You want a professional plan to reach a new personal best and feel more capable.

  • Structure Seekers: You want a 5-run schedule that uses your training time effectively.

Your Deliverables



  • 12 weeks of training syncing to TrainingPeaks for clear session guidance on your watch.

  • 5 purposeful runs per week including easy efforts, interval sessions, and long runs.

  • 2-3 rest days every week to facilitate recovery and consistency.

  • Coach support via email for help with your sessions or practical training advice.
