This event is in the process of updating its Sustainability Strategy in light of its collaborative approach and recent survey. Work to minimise the environmental impacts of this event will continue throughout this process, with particular focus on:

  • Reducing plastic
  • Reducing waste
  • Cutting carbon emissions
  • Responsible procurement

 
In addition, it is striving to improve performance even further by making sure that sustainability is embedded at the heart of the organisation and culture.

Trees not tees

Finisher tees are now optional. You can choose to forgo your finisher tee shirt at the point of entry, and in lieu of this the organiser will make a donation to the National Trust Woodlands Appeal.

The organisers will donate a portion of the fulfilment costs for each runner who chooses this option to the fund and commit that this donation to be a minimum of £20,000 in 2023.
