The countdown is on to the 2022 event, which will take place on June 12, with the organisers saying it will be the best one yet.
There will be four walks on the day in the vicinity of Hart Fell and the Moffat Beeftub.
Each walk has been chosen by team members to provide something for everyone. They all start and finish at the Annan Water Hall.
Route one is to Hart Fell Spa, the spring which was first discovered in 1748. It is 5.5 kilometres long and will take about two hours with 230m of ascent.
Walk two is to Hart Fell summit and is an 11km loop with 640m of ascent and should take approximately 4.5 hours.
The third walk is a circular route following the Annandale Way to the cairn that marks the northern end then up to Whitehope Heights (637m). It is 14 km long and takes up to five and a half hours.
And the longest route is walk four, which has a section of scrambling and is, in part, through trackless hillside.
MMRT say it definitely warrants the ‘Challenge’ in the name and added: “It is the sort of walk you might not think of doing on your own, however it is a rewarding day.”
It is 18 kilometres long in total and could take up to seven hours to finish.
Members of the rescue team will be on-hand throughout the day to help and answer questions.
They are hoping for a good turnout and reminded potential walkers that they can support MMRT or create their own JustGiving page.
