Mr Murphy (62), who established and owned the successful Clearway group of companies, collapsed and died last Wednesday.
The Portadown businessman, who was due to return home on Monday, had gone on the trip with the Blazing Saddles charity cycle group to raise money for the National Council for the Blind of Ireland.
shock
Over the years, Mr Murphy had taken part in various fundraising cycles around the world, and his death has come as a huge shock to everyone who knew him.
Mr Murphy started the Clearway Group of Companies from modest beginnings at the family home on the Brownstown Road, Portadown, in the early 1970s.
In 1978, the company expanded and moved to Dobbin Road, which is now the main headquarters.
The company's main activity is processing and recycling scrap metals but it is also involved in environmental services.
Today, Clearway are one of Ireland's most successful companies, employing more than 160 people both north and south, with around 90 people working at the sites in Portadown and Belfast.
The company also owns the landfill site at Aughrim Quarry just outside Lisburn.
In the Republic of Ireland, the company trades as Hammond Lane Metal Company where it employs 70 staff in Dublin, Cork and Athlone.
The Clearway Group is Ireland's biggest recycler and exporter of scrap metal and was recently listed in the Belfast Telegraph's top 100 Northern Ireland companies.
Mr Murphy, who was a keen cyclist, had travelled the world with the Blazing Saddles group on various charity cycles, raising substantial sums in aid of the blind.
He was also an avid supporter of many local and national charities and was very well-known in the local business community.
family
His other interests included motor cycling and he enjoyed nothing more than spending time with his family and many friends.
Mr Murphy, who lived at Campbells Lane, Portadown, is survived by his wife Dorothy, children Paul, Tracey, Colette and John, and grandchildren Sam, Amy, Kasey, Ellie and Paul.
His funeral will take place tomorrow (Saturday) at St John the Baptist Church, Drumcree, at 2pm, with interment afterwards in the adjoining cemetery.
As a mark of respect all Clearway yards will be closed tomorrow for the funeral, and will re-open as usual on Monday, May 12.
