The South East Mountain Rescue team are hosting their seventh annual fundraiser this evening in Clonmel.
'The Long Way Round' will consist of a 15km route around the Comeragh Mountains.
Those taking part have the option to run or walk while taking in local roads, forest tracks, and the open mountainside.
The event provides the Rescue team with the chance to meet mountain walkers in a positive circumstance.
Liam McCabe is with the Rescue team, and he told WLR News it's a great way to meet the community.
"We usually, obviously, meet in different circumstances, and this is a very enjoyable night out," he said.
Liam wanted to highlight to anyone considering doing the route that it is safe and well marshalled.
There is a list of recommended items to bring on the walk/run, such as rain gear, head torches, and a high-vis vest.
The 15km route will see participants make their way from Carey's Castle Car Park, around the Comeraghs, out at the Holy Years Cross, and back into the town of Clonmel.
There are over 600 people currently booked in, but the Rescue Team are predicting numbers of up to 800.
Liam also told WLR that those taking part can expect some small Christmas surprises.
Runners will leave Clonmel at 6:15pm. Walkers will be taking off in staggered groups five minutes later.
