Campaigners have been walking from Ipswich to Norwich in protest against cuts to mental health services.
They claim services are struggling to cope with long delays for people heading towards a psychiatric crisis who are then offered care in a unit hundreds of miles away.
They will be sending letters to all Norfolk and Suffolk MPs.
"People in Norfolk and Suffolk in mental health crisis, due to a lack of beds, are finding themselves having to be transferred away as far as Darlington, Manchester, Somerset and even Scotland," Emma Corlett from Unison told ITV News Anglia.
"If this happened in physical health, for example if somebody had a stroke and that was the nearest Accident and Emergency bed, we believe that our MPs would quite rightly be falling over themselves to say that immediate action needs to be taken."
