Soldiers from CFB Shilo will be invading Ninette on Thursday.
About 20 soldiers will be running along Highway 23 through Ninette along the lake as well as a route through town.
The race will take place from 6:00 a.m. to 4:00 p.m.
Motorists are advised to be careful when traveling through the area.
The training consists of a 14.8 km run, a grueling 1.9 km canoe portage and a 6.2 km paddle on Pelican Lake.
The entire race will be conducted with a 35 lb backpack.
The training is being held as part of preparation for the 50 km Mountain Man event to be held in Alberta later this summer.
