While 50,000 take to the streets of London, a Virtual London Marathon will also be held for a further 50,000 participants wishing to take part around the country - or even around the world.
Wiltshire Air Ambulance has secured 10 spaces in the Virtual London Marathon.
You will have a full 24 hours to complete your 26.2 miles on the day, so don't miss out. The Official London Marathon app will help you log your miles and enable you to receive a coveted medal and t-shirt for completing the challenge.
The suggested fundraising target for our participants is £200 and we'll provide you with a pack to help you kick-start your sponsorship.
