It's the London 10K with the X-factor, and you need to sign up before the end of play tomorrow, Wednesday, July 16, to get the full experience at the inaugural ASICS LDNX 10K road race.

ASICS LDNX is London's brand new 10K, heading to the iconic Wembley Stadium on Sunday, 24th August 2025. Runners must register by this Wednesday to secure their personalised souvenir bib so thousands of spectators can cheer them on by name on event day. Limited places remain in the current allocation, so you must act fast to get a great price.

When we heard about LDNX, our first thought was: 'Why is it called LDNX?' Fortunately, the organisers anticipated that question and the answer is front and centre on the event website: "The name is based on the home of the event (London) and the Roman numeral for 10 (X)."

The first ASICS LDNX has space for 12,000 entries and is set to be the UK’s largest new 10K featuring epic live music along a fully closed road route, with a finish line on Olympic Way in front of the iconic Wembley arch.

Participants will also enjoy a unique indoor start experience, a buzzing event village and an official after-party at BOXPARK Wembley. Every entry includes a stunning spinning Finisher Medal; Event Pack posted to you in advance; special indoor start experience; After-Party at BOXPARK Wembley; live music (during and after) and top training tips and advice from ASICS experts.

Andrew Smith, CEO of organisers A.S.O. UK, said: “Wembley will be the centre of attention this summer, so alongside iconic football games and record-breaking concerts, this major new 10K will give everyone a chance to perform in legendary surroundings. ASICS LDNX 10K will be an unforgettable experience for those who take part, with some innovations that are unlike any other 10K in the UK."
