With sustainability top of the agenda, the Royal Parks Foundation and Limelight Sports work together to do everything we can to help reduce the impact of the Half Marathon on the environment.


  • Participants receive a Fairtrade cotton bag as they finish, collecting free samples (no flyers/vouchers!) from the Festival site.  This reduces waste as they pick up only what they want.
  • Litter areas set up for the public have clearly labelled bins for recycling and general waste.  These areas are staffed during the event to maximise the amount being recycled.

Sustainable Procurement

  • Participant race t-shirts are made from sustainably sourced bamboo and recycled polyester. Our local supplier works closely with her manufacturer in China to ensure a closed loop of sustainable work practices. 
  • Race shirts are shipped, not flown.
  • Participant medals are made from FSC-certified European wood. The lanyards are made from recycled materials, and a split ring attachment to the wooden medal encourages re-use e.g. as a key fob.
  • Where possible, we produce race branding, signage and décor without dates for re-use in future years.
  • We order only what is necessary, to reduce waste.


  • Exhibitors, charity partners and sponsors are not permitted to “leaflet” within the event site, reducing the paper brought to site and minimising litter. 
  • Balloons are not permitted, due to the potential dangers to wildlife if they get free.
  • All plastic bottles (water and hydration drinks) used on site are collected and taken for recycling locally.
  • In 2013, over 60% of all event waste was recycled.
  • Separate recycling areas for food market traders and other exhibitors ensure that all waste is recycled – particularly packaging
  • Discarded clothing is collected and donated to Oxfam.  Oxfam sorts the clothing for recycling or sale.
  • Surplus food from the catering areas, the exhibitors or the food market is collected at the end of the event and distributed to those in need.

Sustainable Event Management

  • Limelight Sports, our sports management agency partner, has been certified to ISO 20121 (International Standard for Event Sustainability Management Systems) since July 2012 and since March 2010 to BS8901.
  • A stakeholder management record identifies issues, objectives and actions for social, economic and environmental requirements of the event; a key part of the event planning.
  • The event build and de-rig times are managed to minimise the need for artificial lighting –saving energy while ensuring that the Park wildlife is as little disturbed as possible.
  • Participants register online, with all communications via email or social media.  The only exception is the personalised runner’s race pack. Though we encourage collection at various pick up points leading up to the race, a few are sent out shortly before the race with t-shirt, runner number with timing chip, and a folded runner information booklet (printed on recycled stock) containing important on-the-day messages and content from sponsors.
  • Event staff are provided with bicycles to move quickly around the route, keeping vehicle movements to a minimum.
