The importance of organising eco-friendly events

Blog green mudathon eco friendly events hero

As humans we are the biggest threat to planet Earth.

We impact the environment in many ways including overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can be catastrophic and damaging to our beautiful world and unfortunately, these effects are already visible all around us. The Earth is warming, rainfall patterns are changing, and sea levels are rising.

However, we have the knowledge and the tools to be able to turn things around before it's too late. There are things we can put in place right now to work towards a better future for Earth and for all those living on it. If we focus on sustainability, little by little it will improve the quality of our lives, protect our ecosystem, and preserve natural resources for forthcoming generations.

Here at Colliers, we think it’s important to go green. It’s more important than ever for us to minimise our impact on the environment where we can. One of the things we have been doing recently is making sure that when we organise events, we do them with sustainability in mind.

We recently organised The Mudathon, a charity event for both our employees and clients. A 5k extreme mud challenge with over 100 obstacles including lakes, slides, ropes, and lots and lots of mud. Sustainability was high on the priority list for the organising committee, and we made sure that choosing eco-friendly options where possible was central to the decisions we made.

Keeping it local 

We believe supporting local and independent businesses is fundamental to The Mudathon’s sustainable future and therefore all food and drink suppliers were sourced near to the site in Dorking. 

Our coffee supplier, Surrey Horsebox provided us with locally sourced coffee and the superb food was provided by Nyama Catering Co. whose eco-friendly values include, responsible purchasing of foodstuffs from sources that conform to high environmental, social, and animal welfare standards.

Away with plastic!

The Mudathon Committee purchased bamboo trophies, seeded wristbands and gantry from Firebrand Promotions. a carbon neutral local company that plants 10 trees for every order of £500. Our fully recyclable wooden medals were purchased from ZeroWaste Medals

Each T-shirt purchased from Selekt Run & Cycle, were made from 100% post-consumer recycled plastic bottles and we did not purchase 700 bottles of water this year for participants, instead we encouraged people to bring their own to fill at the fresh water taps on site. In fact, by signing up to The Mudathon, everyone taking part helped recycle 4,200 plastic bottles!

Dedicated venue

The Mudathon’s site is based in the Surrey Hills, the event was hosted by Camelot Events and Nuts Founder Wayne Monkman who has been operating outdoor adventures and OCR at his Dorking site for over 25 years. Unlike other OCRs and Mud Runs, Camelot operate from a single site all year round. We really wanted to limit the number of cars on site, therefore communal transport was provided from the local train station. The marquees used were second hand and no new flags or banners have been purchased since pre-COVID.


Go digital, save trees! Our social media campaigns, posts, and emails from start to finish were all online. No paper or printing was used throughout the process. On the day, registration and last-minute sign ups were completed on iPads.

We know that there is still a great deal of work to be done to make the world a more sustainable place, but without the small steps being taken, the larger goals can never be met. We are proud of our achievements, which also saw the event raise a total of £26,100, split equally between our three charities: The Brain Tumour Charity, Small Steps and LandAid.
