Plan Description

If you’re a beginner or intermediate swimmer, or a triathlete looking to improve your swim performance, the Zero to Hero: Sub-7 400m Swim Plan is a focused 4-week training block designed to help bring your 400m swim time down towards the 7-minute barrier.

Rather than simply adding more volume, this plan uses structured, purposeful sessions to improve the specific fitness and pacing needed to swim a faster, more efficient 400m.

Who Is This Plan For?
Ideal for:
🔹 Beginner and intermediate swimmers
🔹 Triathletes wanting stronger swim fitness
🔹 Athletes already swimming consistently
🔹 Swimmers targeting a faster 400m time

This plan works best for athletes currently swimming approximately:
🔹 Approx 7:30 for 400m
🔹 Or close to breaking the 7-minute barrier

What Does The Plan Focus On?
Across the 4 weeks, sessions are designed to improve:
🔹 Threshold swim speed
🔹 Race pace familiarity
🔹 Aerobic endurance
🔹 Speed endurance under fatigue
🔹 Pacing control and efficiency
The aim is not just to swim harder, but to hold a stronger pace for longer while maintaining good form.

What’s Included?
The plan includes a progressive mix of:
🔹 Structured interval sessions
🔹 Race pace work
🔹 Aerobic support sets
🔹 Controlled speed endurance training
🔹 Technique-focused swimming
Sessions build week by week to steadily improve confidence, pacing, and swim fitness.

The Bigger Picture
The goal of this plan is simple:
🔹 Become fitter
🔹 Become more efficient
🔹Become more confident swimming at speed
And move yourself closer towards that sub-7 minute 400m benchmark
