Longest Day still to come.
David Wade, Mick Levett and Adam Brannan will be aiming to complete the Longest Day challenge in aid of the Macmillan Cancer Relief charity next week.
The lads will be aiming to play an incredible 72 holes of golf in just one day on July 7.
They aim to start at 5am at Hunley Hall, before moving on to complete a round each at Wilton, Saltburn and Cleveland golf clubs before dusk.
David, a 39-year-old nine handicapper from Marske, said: "We've all been trying to get in as much training as possible so we're ready for the physical demands of 72 holes in one day.
"It'll be pretty much non-stop and so we all need to be as fit as possible on the day."
All three lads have been road running in preparation for the big day, which will see them tramp almost 16 miles across some of Teesside's finest golf holes.
Adam, a 47-year-old recruiter for the Navy and Royal Marines in Middlesbrough, has a handicap of 21, while Mick, who plays off 16, is aged 52 and lives in Thornaby.
He's a member at the Ingleby Barwick club.
