4 ways whose technology feeds sustainability at 2025 London Marathon

While more than 56,000 runners launched for the 2025 London marathon, many had relied on technology throughout their training course. A booming wearable market should be worth $ 171 billion By 2032, and GPS watches, mobile applications and platforms powered by AI collect data that allow runners to optimize performance.

The organizers of the London marathon also count on an innovative technology, not only to offer a transparent event but to reduce its environmental impact. From the smarter and reducing logistics of waste, transforming the urine of runners into fertilizer investments and carbon elimination, the organizers take advantage of the technology for the impact.

In a world where sports tourism is boomingAnd its carbon footprint rising, London Marathon’s sustainability initiatives provide information on how major events can balance performance with responsibility.

1. Circular technology creates fertilizers from urine

A start-up that recovers the nutrients from human urine to create fertilizers based on biosorps will take advantage of the toilets before the race this year. Around 1,000 liters of urine will be collected and transformed into fertilizers, to be used in tests to assess its performance on wheat growth. In a conversion process similar to the treatment of wastewater, bacteria will be added to create ammonium nitrate, which plants must develop.

Hannah Van Den Bergh, founder of NPK Recovery, the organization responsible for the new manufacturing technology, has shared: “Urine must not be waste and we are delighted to play a small role to help support the sustainability commitments of the emblematic London marathon.”

Urine is collected in an innovative sex equalizing the urinals of women, which are three times faster to use than regular portable toilets. Amber Prombyn, co-founder of Peequal, said: “We like to come to the TCS London marathon because we firmly believe that women should not have to choose between starting their race or waiting to go to Loo.”

Kate Chapman, responsible for sustainability for the events of the London marathon, said: “Part of our environmental strategy is to try to find a” forward use “for all waste generated during our events, for example composting, reuse, high school and much more.”

2. Application measures and reports have an impact

A cloud apply For the planning of responsible events, planning allows London marathon events to follow, measure and report the environmental and social impacts of the marathon in real time. It helps organizers to write carbon savings, to identify improvement areas and to transparently communicate their progress to Net Zero by 2030.

Transparent and verifiable impact reports have helped LME recently Become the first sports organization to achieve the “persistent leaves” status of the responsible sports council, recognizing its leadership in the creation of positive social and environmental changes.

Michelle Sandquist, certification director common“London Marathon Events has established a new world reference for what means leading with a goal. Their work illustrates what is possible when innovation, responsibility and the community are at the heart of the planning of events. ”

3. Elimination of carbon to combat travel emissions

More than 56,000 people will travel worldwide To participate in the London TCS 2025 marathon, which creates a lot of carbon emissions. To compensate, the organizers invoice international participants a climate levy of £ 26 ($ 34) from registration, which is used for carbon elimination. Technological solutions such as direct air capture, biochar and improved bad weather is among the supported carbon methods.

“This initiative is valuable because it reduces not only the programs but also aware,” said LME’s financial director, Jeanette Wong recently. “Encourage people to think about their travel choices is an important step in change in behavior.”

In the most recent published sustainability of LME report From 2023, Green House Scope 3 gas emissions, which are those caused by participants’ trips, the activity of the supply chain and the life cycle of the products purchased, represented more than 99% of the carbon footprint of the marathon.

4. Event management software cuts waste

Waste creation is a huge donor at the environmental imprint of sporting events. To solve this problem, the London marathon uses intelligent registration technology that poses key questions to runners to help reduce waste. Participants are asked if they wish to receive a medal from a finisher, allowing organizers to produce only what is necessary and to reduce the manufacturing and excess shipping emissions. The runners also have the possibility of planting a tree instead of receiving a t-shirt from a finisher, helping to reduce the environmental impact of textile production while supporting reforestation efforts.

For those who choose to receive a medal, some are available to ready On the finish line, to take photos and capture the moment. The medals are made from recycled and loose zinc alloy to reduce travel emissions, medals and ribbons are recycled in the United Kingdom

Intelligent logistics is at the heart of the new luggage Assembly area. The green runners of the team who avoid bringing a bag of kit or depositing it the day before the race help reduce the need for luggage trucks. This reduces fuel emissions and improves logistics efficiency on the day of the marathon.

The TCS London Marathon’s 2025 sustainability Efforts show that daring ideas and technology can help the largest breeds in the world to determine more lightly. From the conversion of waste to resources to the elimination of atmosphere carbon, each initiative reflects a deeper change of mentality, which favors innovation, responsibility and long -term impact. While global sports tourism continues to grow, the London marathon gives a powerful example, the future of major events does not only lie in performance and spectacle, but in the way they are delivered in a responsible manner.
