As many big city marathons aim to adopt greener practices, the 2025 TCS London Marathon has introduced a finisher medal policy that has confused many 2025 participants.
Since its inception in 1981, the TCS London Marathon has been known for its tradition of handing out medals at the finish line on Pall Mall, in front of Buckingham Palace. However, this year, the 56,000 participants must choose whether to receive a medal or to opt out via their registration portal. The move is part of the event’s sustainability efforts to reduce the event’s impact on the environment.
One major factor behind this change is the environmental impact of finisher medals and T-shirts. Both items are manufactured in China and significantly contribute to the marathon’s carbon footprint.
The policy has caused turmoil among some participants, who have taken to Facebook groups to voice their opinion. One participant wrote, “Who the hell runs a marathon and doesn’t want a medal?! It should be the other way round, log in to opt out of a medal!”
Another added, “Completing the race is an achievement in itself, and everyone who finishes deserves recognition and a medal. It’s about effort, perseverance, and the spirit of pushing through to the finish line!”
To navigate concerns, the organizers have assured that any participant who wants a medal on race day will still be able to receive one, even if they forget to update their registration before the April 22, 4 p.m. GMT deadline.
If participants opt out, they can choose the sustainable alternative: planting a tree. Through a partnership with Trees Not Tees, participants can contribute to reforestation projects in the U.K. Those who choose this option will instead receive a digital certificate featuring their tree’s photo and geolocation, allowing them to visit it if they wish.
In addition to the broader sustainability push, London Marathon organizers encourage participants to travel to the start line on foot, by bicycle, or via public transport on April 27.
