Meet the founder

"I created Rokman to inspire action"

Hi, I'm Terry Rosoman, challenge enthusiast and Rokman Founder. Having experienced firsthand the transformative power of embracing physical challenges in my fitness journey, I came to recognise the profound impact it had on my mental well-being.

These challenges offer more than just physical exertion; they provide a sense of purpose and direction, pushing us to explore and expand our boundaries while fortifying our resilience to navigate life's daily stresses.

Observing the growing struggle among those around me to find time and motivation for training, and witnessing the toll it took on their mental health, I felt compelled to create Rokman. It's a platform designed to eliminate the barriers typically associated with race day events, igniting a passion for self-improvement among its members. Rokman aims to make pushing your limits achievable for anyone, regardless of their schedule or ability level.

our ethos

Welcome the pain. Embrace the suffering.

Without meaningful trials of strength and courage we stagnate, weaken and never truly flourish in life. Let's embrace adversity and run the gauntlet together, to test and further and limits and reach our greatest potential.

You've heard of the Beep Test? Well, this is like the Beep Test on a bad day. A really bad day.

Choose your starting time limit and then keep covering a distance of 400m within that limit until failure. However, here's the kicker.

Week 4

Pressure Cooker KM

Starting Target


Split Reduction


Like the Pressure Cooker Quarter Mile Challenge, this test requires participants to run mile split times for as long as possible starting with the target time given.

No. Rokman challenge series offer a variety of different levels of entry to suit all fitness levels, from novice all the way up to advanced.

How does it work?

How does it work?

How long do we have to complete each challenge?

We recommend that you complete each challenge within 7-days from the date of issue. However, we understand that life can often get in the way, so that’s why accept submissions up until 7-days after the end of the series.

What is someone cheats?

We do our very best to weed out any cheating by asking people to evidence their challenge attempts. However, due to the nature of this being an online challenge series, it’s not 100% fool proof.We have to take everyone’s submissions at face-value. If we can confidently identify people either cheating or doing the challenge incorrectly, we will notify the competitor privately via email.At the end of the day, the leaderboard is just a bit of competitive fun. These challenges are personal tests of resilience. If people decide to cheat, they’re only cheating themselves. If you concentrate on yourself and give your best honest performance then you can hold your head high at the end of the day.

Do you offer refunds?

Unfortunately, we unable to offer refunds on challenge series entry, however, we do offer transfers. If you’re unable to take part in this challenge series, let us know and we can transfer you on to an alternative series.
