There's just a few days until thousands of runners take to the streets for this year's London Marathon.

Most people who take to the start line on Sunday have their own reason as to why they're taking part, and many are also running to raise money for charity.

Preya Vaja from Leicester is running for the charity 'Group B Strep Support'. Preya's baby Uma nearly died in childbirth due to sepsis caused by Group B Strep - a bacterial infection that can be easily identified by a swab test.

The infection kills one newborn every week in the UK and yet many pregnant women have never heard of it.

Preya told Ady Dayman how she's prepared for a Marathon after such a challenging experience.
