Clive Wooster from Famosa and Damien Weight from Tomy are to undertake another challenge in aid of the Brainstrust next month.
The duo will attempt to walk north to south and east to west across the Isle of Wight in two days - March 18th and 19th.
Starting at the most northerly point - Cowes - they will head south to St Catherones Point on day one, covering over 25 miles.
On day two, they will start at the most easterly point - Bembridge - and across west to the Needles, notching up another 25 miles.
Wooster commented: "We've done the coastal path around the island in the past, but this time will leave the well sign-posted route and take a path literally less travelled. We will cross the little visited interior of the island, climbing through forgotten valleys, fording streams, warding off wild animals and possibly encountering the occasional Lidl."
