Here's what previous runners had to say
“I’d really recommend anyone who is thinking of taking on a race or other challenge in memory of a loved one to just go for it.” – Suzanne, who took part in the Royal Parks Half Marathon 2024, exactly one year to the date since losing her Mum to acute myeloid leukaemia (AML).
