4-week swim training foundations for triathletes

Who's it for?

Start your triathlon swim training the right way

Double Your Distance is a 4-week program designed to help triathletes build the confidence and capability needed to train effectively in the water.

It’s not about learning to swim. It’s about learning how to train your swim, giving you the fundamentals required to progress.

"If you’ve raced before but never properly trained your swim, this is a great place to start."

Designed for triathletes getting started with swim training

Follow structured weekly sessions that steadily build speed, endurance, and race control.

New to structured swim sessions

Comfortable in the water but lacking direction

Focused more on bike and run until now

Want to improve swim performance without guesswork

How it works

A simple, structured 4-week progression

Over four weeks, you’ll follow a clear progression designed to help you build distance, improve technique, and develop consistency in the water. Train with structure, not guesswork.

Confidence first. Performance next

The focus is on:

Developing sustainable swim endurance

Understanding pacing and effort

Improving technique through in-depth video breakdowns and specific drills

Building consistency in your training routine

Each week builds on the last, so you can progress without feeling overwhelmed.

Train with structure from day one

Every session includes clear guidance, structured sets with defined purpose, and a repeatable format you can follow with confidence.

Start strong. Keep progressing.

Double Your Distance prepares you to step into structured, ongoing training.

This is your starting point. The next step is building on it with TRI Swim Club.

Helping triathletes build confidence and consistency in the water

Everyone starts somewhere. This is where progress begins.

Finally seeing real improvement

Before Tri Swim Club I felt stuck swimming the same times with no clear direction. The program completely changed how I train, and now I’m seeing real improvements in both my technique and speed.

Breaking through a swim plateau

Ziggy’s programming helped me break through my swimming plateau. The workouts are perfectly structured for triathletes, with purposeful drills and no wasted sets. I can’t imagine following any other swim program.

Purposeful workouts that deliver results

Tri Swim Club completely changed my swimming. In six weeks I dropped 15 seconds off my 100 pace. Ziggy’s focus on technique and purposeful session structure makes every workout clear, progressive, and effective.

Structure that builds motivation

Even as a former college swimmer, it’s hard to stay motivated in the pool. Coach Zach provided the structure and guidance I needed to stay focused, improve my swimming, and complete my first 70.3.

Swimming became the best part

Swimming used to be my least favorite part of triathlon, but Tri Swim Club changed that completely. The training helped me feel relaxed and strong in the water, and I even set a personal best on race day.

A swim program that actually works

After years of racing triathlons, this is the first swim program that truly worked for me. Ziggy’s stroke analysis and structured workouts helped me improve immediately while keeping sessions challenging but achievable.

From beginner to distance swimmer

Two months ago I could barely swim 50 yards. After a stroke analysis with Ziggy and six weeks in Tri Swim Club, I swam 2,200 yards non-stop at under 2:00 per 100 pace. The improvement has been incredible.

Could not recommend the TRI Swim Club enough!

Ziggy was amazing at providing feedback on my technique and after implementing some of the drills he suggested, my stroke and speed in the water improved massively.

A Completely Different Approach and It Works

My speed is at a level I've never had before. I got out of the water feeling fresh, had a great T1, and it set up my whole bike. Now we're building toward Kona together.

FAQ

Who is this program for?

Double Your Distance is a 4-week program designed for triathletes who are comfortable in the water but new to structured swim training. If you've been focused on bike and run and have been getting by in the swim, or if you've raced before but never properly trained your swim, this is the right starting point.

Is this a learn-to-swim program?

No. Double Your Distance assumes you can already swim at least 800 meters. It's about learning how to train your swim, developing pacing, endurance, efficiency, and consistency so you can progress with purpose rather than guesswork.

What does a typical week look like?

The program includes three structured workouts per week, strategically designed to build and progress over a four-week cycle. Each week includes video lessons from Coach Ziggy with defined sets, drills, and effort levels, so you always know what you’re doing and why.

What happens after I finish the four weeks?

Double Your Distance is designed as a stepping stone into TRI Swim Club, the ongoing monthly training program. By the end of the four weeks you'll have the confidence, structure, and habits to train consistently at the next level.

Do I get access to Coach Ziggy?

Yes. Double Your Distance is supported through the TRI Swim Club app, which includes coach support and feedback via in-app messaging.

Do I get access to the TRI Swim Club community?

Double Your Distance is a standalone 4-week program and doesn't include access to the TRI Swim Club community. If you're looking for that, joining TRI Swim Club after completing the program will give you access to the full community alongside your ongoing training.

How much does Double Your Distance cost?

Double Your Distance is a one-time payment of $40. There's no subscription or ongoing commitment. Buy it once and own it forever.
