Following two hugely successful events at HMP Brixton and HMP Newhall, the Prison Reform Trust is proud to partner with HMP Liverpool Physical Education Instructors to host the a full marathon inside a British prison.

I was lucky enough to run a three-hour timed race in a women's prison last year, and I found it a truly humbling experience. I'm excited to take part in this marathon at HMP Liverpool. I know how powerful running can be, and how important exercise is to the rehabilitation of inmates.

Any donation, however small would be so appreciated
