An epic run

For half a century, TCS has been a trusted partner in the UK, driving innovation and progress. As we mark this milestone, our commitment to making a difference continues—on the roads of London and beyond.

On April 27, 2025, the sporting world’s focus will shift to the British capital for the 44th TCS London Marathon 2025. Thousands of runners will gather at the starting line in Blackheath. The historic 26.2-mile route, which culminates at The Mall, will take runners past some of the city’s most famous landmarks, including The Cutty Sark, Buckingham Palace, and Tower Bridge.

In a precursor to the marathon, the TCS London Marathon Running Show 2025 will be held from Wednesday, April 23, to Saturday, 26 April, at ExCeL London. And on April 26, the TCS Mini London Marathon will once again feature a one-mile for children in Reception to Year 7 and a 2.6K route for children in Reception to Year 7 and a 2.6K route for those in Years 4 to 12 who can go a bit further.

Many milestones

The TCS London Marathon has come a long way since the inaugural race in 1981. More than a million people have crossed the finish line since then, and over £1.3 billion has been raised for charity.

Along the way, there have been several inspiring feats by athletes, including multiple world records being broken. The 2024 TCS London Marathon witnessed Elite runner Peres Jepchirchir set a new world record by reaching the finish line in 02:16:16, becoming the fastest female marathon runner.

The men’s course record was set in 2023 by Kelvin Kiptum, who broke the 2019 record held by Kenya’s Eliud Kipchoge, a four-time winner of the event and arguably the greatest marathon runner of all time. Kipchoge is set to run again in the 2025 edition of TCS London Marathon.. Marcel Hug set the men’s course record in the wheelchair race in 2022, while Catherine Debrunner broke the women’s record.

Going virtual

TCS first developed the TCS London Marathon Official App in 2016. Following the pandemic in 2020, the app was refreshed to support the first virtually held marathon. It brought together 38,000 people from across the globe as they competed remotely and got the marathon a Guinness World Records title for ‘Most users to run a remote marathon in 24 hours’. The 2024 edition of the TCS London Marathon app (downloaded 685,000+ times) – and the marathon itself – was no different. Every participant, whether running in person or taking part in the ‘MyWay’ virtual event, was in the running (quite literally!) for a medal.

The app re-energized and inspired MyWay participants with different soundtracks and the Belief Booster feature. The latter let participants’ families and friends in on the excitement, too, allowing them to send out messages of encouragement. Several of these were flashed on giant screens at the finish line.

Imagine the difference

TCS’ innovations in the digital space are creating new possibilities for athletes. Using our Digital Twin technology, we have been working with two-time Olympian and Boston Marathon Champion Des Linden to create the first-ever digital heart of a long-distance runner. The technology aims to help athletes better measure their health and performance.

TCS is also making the London Marathon more accessible and inclusive, uniting communities, amplifying fundraising, and inspiring more people to stay active. As part of a unique initiative to encourage schools to participate in the TCS Mini London Marathon, TCS rewards every child who finished the event by offering £10 to their schools to help enhance PE or IT equipment.  equipment.
