The 3 Dads Walking have officially released their first book, 300 miles of hope. 

Mike Palmer, from Greater Manchester, Andy Airey from Cumbria and Tim Owen, from Norfolk, known as 3 Dads Walking, all tragically lost their daughters to suicide.

But they have turned that pain into strength, and have established themselves as national heroes in their work raising awareness and saving young lives. 

They walked 500 miles from Scotland to Norwich earlier this year, raising over £1.4 million for the suicide-prevention charity PAPYRUS.

They said: "We were (and are) three ordinary dads who found ourselves in a desperate place we never expected to be, engulfed by pain and suffering beyond imagining, but who chose to push back, to not allow it to overwhelm us, to build something positive from the shattered pieces of our lives. We wanted to do something... and this is what it became: Three Dads Walking."

In memory of their young daughters - Sophie, Beth and Emily, three dads set out on a 300-mile journey across the country, from the windswept Lakeland fells and Peak District dales to the open plains of the eastern Fens.

The book description is as follows: "Putting one foot in front of the other in spite of their pain, they capture the hearts of millions: laughing together, crying together, fighting to be heard. With each hill climbed and story shared, they begin to rediscover their faith in humanity and are inspired by the kindness of strangers across the land.

"Woven around personal diary entries and their own experiences of deep grief, their book, told in three distinct parts by each dad, grows into a beacon of hope for anyone struggling. It's about the power of speaking out, of friendship, laughter and courage (and blisters). The three dads bear a heavy load, but they walk on for us all, finding light on the path after the darkest times."

The book includes a foreword from Dan Walker and has been praised by the likes of Andy Burnham, Daniel Craig and Nicole Kidman.

It is available to purchase online and in bookshops now in hardback, paperback, kindle and audiobook editions.
