24 Week Advanced Competitive Full Distance Training Plan - 2026

This plan is for experienced athletes preparing for a full distance / 140.6 race with a performance goal, and who are ready for a more demanding, structured build. It is written in the way we coach at TCC Endurance: practical, progressive, honest, and built around consistent training rather than chasing one-off hero sessions.

Across the 24 weeks you will build towards race-specific fitness with a strong mix of endurance, controlled intensity, longer key sessions and taper. The weekly volume sits around 8 ½-18 hours, so this is best suited to athletes who already know they can handle consistent long-course training.

Who this plan is for

• Advanced Competitive athletes preparing for a full distance / 140.6 triathlon.


• Athletes with long-course experience or a strong endurance background who want a more performance-focused plan.


• People who want structure, progression and clear guidance rather than a random collection of sessions.


• Athletes who can train most weeks between 8 ½-18 hours.

What to expect

The plan includes structured swim, bike and run sessions with clear purpose behind the work. You will move through base fitness, endurance development, race-specific preparation and taper, with the key sessions placed where they matter most.

The aim is to help you arrive at race day fit, sharp, confident, and ready to make good decisions when the distance starts asking questions.

TCC coaching approach

At TCC Endurance we believe the best long-course results come from consistency, smart progression and knowing when to push and when to absorb the work. This plan reflects that. There are challenging weeks, but the training is there for a reason, and the easier days are just as important as the harder ones.

If you follow the plan well, listen to your body, and keep the bigger picture in mind, you will give yourself a strong platform for a successful full distance race.

Included in the plan

• 24 weeks of structured full distance training.


• Swim, bike, run and supporting endurance sessions.


• Progressive weekly structure leading into race-specific preparation.


• Clear session guidance so you know what each workout is trying to achieve.


• A taper into race day so you arrive fresh and ready, not flattened by the training.

This plan has been reviewed and updated for the 2026 season.
