Hi,

My name is Tim Sorensen, and I’ve been in endurance sports since the 90's—as a marathoner, triathlete, and Ironman competitor.

But my early years looked like those of many endurance athletes.

I was training hard, dealing with recurring injuries, and constantly restarting just when things felt like they were clicking.

I thought the answer was to push harder.

It wasn’t.

The real issue was how my body moved—and the weak links I didn’t even know were there.

Once I started fixing that, everything changed.
I could train consistently, recover better, and finally build momentum.

That shift led me down a deeper path—studying movement, durability, and performance.

Since going full-time as a coach in 2010, I’ve earned certifications in personal training, corrective exercise, nutrition, and triathlon coaching, and I’ve coached athletes at every level—from first-timers to Ironman finishers.

But here’s what matters most…

I’ve helped hundreds of athletes go from injury-prone and frustrated
to durable, confident, and training consistently again.

Because at the end of the day, it’s not about how hard you train.

It’s whether your body can actually handle it.

But you probably don’t care about my background.
You just want to know if this will actually work for you.

Well, for athletes stuck in the cycle of training, getting hurt, and starting over…
this is exactly what I built this for.

That’s exactly what I teach inside the 14-Day Durability Kickstart.

Who Is This Course For?

This Course Was Built for Triathletes Who:

  • Deal with a nagging injury that never fully goes away

  • Build momentum—only for something to flare up and set them back

  • Put in the work—but their bodies aren’t holding up

What Categories Do We Focus On?

  • Identifying weak links that may be contributing to recurring strain

  • ​Restoring mobility in hips, ankles, and shoulders so your body moves the way it’s supposed to

  • ​Improving run mechanics to reduce impact and stop overloading the same areas

  • ​Building strength in the specific areas that break down under training

  • ​Connecting movement across swim, bike, and run so everything works together

  • ​And so much more!

Who Is This Course NOT For?

  • You want a quick fix instead of lasting change.

  • You’re unwilling to stay consistent with simple, focused work 

Frequently Asked Questions

Can I participate while working around pain or injury?

Yes—if you’ve been cleared to train.

You don’t need to be completely pain-free to start. This course teaches you to move more efficiently and reduce unnecessary strain—helping lower injury risk and rebuild consistency.

It can also help bridge the gap between injury recovery and returning to regular training.

As with any training program, participation involves risk. Stop if symptoms worsen and consult a qualified healthcare professional.

How long do I have access to the program & when does it start?

You get immediate access as soon as you join.

There’s no waiting, no start dates, and no schedule to keep up with. You can begin right away and move through the program at your own pace.

You’ll also have lifetime access, so you can revisit the material anytime—whether you’re working through something now or coming back later to stay consistent.

Can't I learn all of this on Youtube?

You can find pieces of this on YouTube.

The problem is it’s scattered, inconsistent, and not built around you.

One video tells you to stretch. Another says strengthen. Another contradicts both.

So you end up guessing… trying things… and staying stuck in the same cycle.

This program gives you a clear, step-by-step approach—so you know exactly what to do, when to do it, and how it applies to your training.

Instead of bouncing between random advice, you’re following a system designed to build lasting durability.

Do I need to have a certain fitness level before starting?

No.

This is built for where you are right now—Even if you’re returning from time off or rebuilding consistency.

Everything is designed to be adjusted to your current ability, so you can start without making things worse.

You’re not expected to be “ready.”

You start where you are, use what you have, and do what you can.

Should I do this before hiring a coach or following a training plan?

You can—but most athletes run into the same problem.

They follow a plan or work with a coach…
but the underlying movement issues never get addressed.

So the same tightness, breakdowns, and flare-ups keep showing up.

This fills that gap.

It builds the mobility and movement foundation your training depends on—so your body can actually handle the work.

When your foundation improves, everything else starts working better.
