So I've finally given in and agreed to do a half marathon but only because of this fantastic charity.

Terrence Higgins Trust is the UK's leading HIV and sexual health charity. We support people living with HIV and amplify their voices, and help the people using our services to achieve good sexual health.

Your support helps us work towards a world where:

• There are no new HIV cases.

• People living with HIV get the support they need.

• Everyone can access good quality sexual and reproductive health services and information tailored to their individual needs.

• HIV and sexual and reproductive health free from shame and stigma.
