Awards and Accreditation

We’re proud to be one of the most accredited and award-winning outdoor adventure providers in the UK. But don’t just take our word for it; take a look below at the various awards that have been bestowed on us over the years!

2025

We will always be proudest of any awards that recognise our exceptional customer service or dedication to young people and 2025 was certainly the year that this was recognised in abundance!

BRENTWOOD BUSINESS AWARDS:

CONTINUED PROFESSIONAL DEVELOPMENT:

2024

In 2024, we were proud to be recognised as Best Small / Medium Business and a Finalist in Best Customer Service. These awards celebrate the passion, dedication, and energy our team puts into every experience, and remind us why we love what we do!

BRENTWOOD BUSINESS AWARDS:

2023

Gaining recognition from the board of experts that do what we do well – Obstacle Racing – is truly special. 2023 was a great year, when we scooped four awards at the UK OCR Awards.

UK OCR AWARDS:

2021

2021 was a standout year for us, with big wins at the UK OCR Awards. We were thrilled to take home Obstacle of the Year and Best Training Facility, celebrating the dedication, creativity, and hard work our team puts into every course and experience.

UK OCR AWARDS:

Another year of winning big at the Mudstacle Awards (indeed, having won the UK’s Best All Round Obstacle Race for the 6th consecutive year) and at the Running Awards, both of which we’re very proud of. 

RUNNING AWARDS:

MUDSTACLE AWARDS:

2018

Another year of winning big at the Mudstacle Awards  (that makes 18 industry Mudstacle Awards in 5 years!) and our first time winning at the Racing Awards – something different for us but one which we’re nonetheless very proud of. After all, there’s lots of running involved in our races, as much as there is obstacle tackling!

RUNNING AWARDS:

MUDSTACLE AWARDS:

2017

Nuclear Essex is for everyone – kids, adults, beginners, athletes and even our spectators! And 2017 was definitely a year that celebrated our entire customer base, as it rightly should.

It’s always good to know that we’re doing a great job overall in all aspects of Nuclear Essex, and our two wins at the Mudstacle Awards in 2016 certainly celebrated this!

MUDSTACLE AWARDS:

2015

2015 was the year of the obstacle! And our awards at the Mudstacle Awards certainly recognised this…

MUDSTACLE AWARDS:

2014

Where it all began: with the mud, the obstacles and providing fantastic events for our adults and children of all abilities and fitness levels across Essex and beyond:
