About this event
The TCS London Marathon is one of the most popular marathons in the world and in 2026 we will be cheering on our team as they embark on this remarkable adventure, turning their passion into action and their miles into meaningful change.
Turn your marathon dreams into reality and join Team SIA in 2026
We have a limited number of London Marathon places each year. As such, we ask anyone who is interested in running for us to fill out our application form as early as possible. This helps us shortlist all interested supporters and choose our team members.
Fundraising target: £2000
** The deadline for applications closed at 10pm Monday 16 June 2025. We are currently reviewing and will be informing the successful applicants by the end of June. Please note these timings may be subject to change.
Official ballot and own place runners
In addition to applying directly with us, we highly recommend everyone enters the London Marathon public ballot, as this will maximise your chances of taking part. The winners are drawn at random, so everyone has an equal chance – it’s all about the luck of the draw.
** The 2026 ballot closed on Friday 2 May 2025 and results of the ballot were announced on 19 June 2025.
If you are lucky enough to be successful in the public ballot, then we would love you to join #TeamSIA! You will receive all the same benefits as our charity place runners (see below) Please contact our challenge events team to find out more:
