Frequently Asked Questions

Do I need to be mega fit?

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 monthly 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.

What if I don't enjoy it, can I get a refund?

Absolutely! If you try it and decide it's not for you, we offer a 30-day no questions asked money back guarantee.

Can I use a treadmill?

All running challenges are designed to undertaken outside, however, if you are unable to go outside we will accept treadmill entries. If participating on a treadmill, the treadmill must be set at a 2.5 degree angle.
