Trees Not Tees

Tess Not Trees x Mourne Mountain Marathon

We’re working with Trees Not Tees, to offer competitors the option to plant a tree instead of receiving a t-shirt! 🌳


Why Trees Not Tees?

Trees Not Tees is an innovative initiative aimed at reducing waste and supporting reforestation efforts. Each year, millions of event t-shirts and other swag items are produced, many of which end up in landfills.

By choosing to plant a tree instead, competitors can make a positive environmental impact and contribute to the fight against climate change.


How It Works

When entering for the Mourne Mountain Marathon, you will now have the option to opt-out of receiving a t-shirt and choose to plant a tree instead.

Simply tick the box on the entry form. For those who still want a t-shirt, don’t worry, that option is still available too.


The Benefits of Planting Trees

  • Environmental Impact: Planting a tree helps remove carbon dioxide from the atmosphere, providing clean air and combating climate change.
  • Biodiversity: Trees provide habitats for a diverse range of species, supporting wildlife and promoting ecological balance.
  • Sustainability: By reducing the production and disposal of t-shirts, we can lower water usage, pollution, and waste.


Personalised Certificates

Competitors who choose to plant a tree will receive a personalised e-certificate from Trees Not Tees. This certificate includes a photo of your tree, its species and the what3words geolocation of where it’s planted.

It’s a wonderful keepsake to commemorate your contribution to a greener planet and can be proudly shared on social media.


Join the Movement

By partnering with Trees Not Tees, the Mourne Mountain Marathon is taking a significant step towards sustainability. We encourage all competitors to consider this option and help us make a positive environmental impact.
