Plan Description


Your Half Distance | 20-Week Beginner Confidence Plan


Stepping up to a Half Distance Triathlon is a massive personal challenge. This 20-week program provides a patient path to the finish line, removing the guesswork from your training. We focus on building the belief that you can handle the 1.9km swim, 90km bike, and 21.1km run. This is about proving to yourself that you can achieve a major goal through a long, consistent build that fits around your professional life and family commitments.


For a developing swimmer, the priority is better technique and feeling calm in the water. The 20-week schedule allows for a very safe and steady progression of stamina. You will build the strength needed for the distance while slowly introducing sessions that help you find a comfortable pace. This approach makes sure you build the belief needed to finish your race with pride. Every training hour helps you feel more prepared and confident for your race morning.

How This Helps You



  • Technique: Simple swim sessions to help you move through the water with less effort.

  • Routine: A professional schedule that works with your career and focuses on useful sessions.

  • Pacing: Guidance to help you manage your effort on the bike to protect your run.

  • Strength: Included work to help your body stay resilient as you build volume.

  • No Guesswork: Every workout uses personal targets so you know exactly how hard to work.

Your 20-Week Roadmap



  • Weeks 1-5: Routine. Find your current pace and build a solid foundation of stamina for the weeks ahead.

  • Weeks 6-12: Build. Safely increase your training time and work on your skills as you build confidence.

  • Weeks 13-17: Simulation. Practice your race-day efforts, pacing, and nutrition strategies.

  • Weeks 18-20: Readiness. A simple taper to help your body recover so you feel prepared.

Is This Your Next Step?



  • Developing Swimmers: You swim 100m in 2:30–3:30, cycle for an hour, and run for 40m.

  • First-Timers: You want a reliable, long-term plan to build the belief that you can finish.

  • Structure Seekers: You want a professional plan that tells you exactly what to do each day.

Your Deliverables



  • 20 weeks of training syncing to TrainingPeaks for clear session guidance on your devices.

  • 5-8 purposeful sessions per week including Swim, Bike, Run, and Strength.

  • 2 essential rest days every week to help your body recover and stay consistent.

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