If you know someone who is taking part in the mass event, you can now use the Official TCS London Marathon App to send them a motivational Belief Booster to help them complete their 26.2 miles with a smile! Simply type out your Belief Booster message of support and, if approved, it will appear on the world-famous gantry on The Mall as your chosen participant approaches the Finish Line. 

Supporters can also use the Official TCS London Marathon App to:

• follow participants’ progress
• keep up-to-date with the Elite Leaderboard
• and find out results.

Meanwhile, if you’re a participant, you can use the Official TCS London Marathon App to:

• record your 26.2 miles
• track other participants (and invite friends and family to track them too!)
• listen to an inspiring soundtrack
• take selfies to post on social media
• find expert tips and advice
• and much more!

If you're a participant who has signed up on our official fundraising platform, your supporters can donate to your chosen charity via the Official TCS London Marathon App while they cheer you on. A ‘Donate’ button will appear on your tracking page, making it even easier for family and friends to give towards your special cause!

Don’t miss your chance to take advantage of the Official TCS London Marathon App, powered by TCS, and make even more memories on Marathon Day.
