Ron Ostrom of Yellowknife has set a goal of walking around the Frame Lake Trail 365 times this year, and has already gone around the lake 195 times since January.
In total, Ostrom intends to walk 2,900 kilometres, roughly the same distance as walking from Yellowknife to Edmonton and back.
"It's not that hard to get motivated," he said.
"It's so beautiful out here on the trail. People ask me all the time, 'You're out here all the time, don't you get bored?' But every single day it's different out here, whether it's the lighting versus the changing of the colours out here to sometimes there's snow. Every day it's a different experience and it's always beautiful. Very rarely do I have to drag myself out here."
His sister, Julie Warnock, has been along for most of his walks.
"When we were really little, Ron used to, for recreation, run around and around the outside of the house and count how many times he was doing that," she said. "So he's always been a loop kind of guy."
Some Yellowknifers are wary of the trail, as it has been the site of a number of assaults, sexual assaults and robberies.
Yellowknife mayor Mark Heyck says the perception that the trail is not safe is driven by media.
"We've talked to the RCMP many times and they don't deem it an unsafe trail by any means," he said.
"People really, really enjoy it. It's one of the premier lakeside trails that I think you'll see in any community across Canada."
"Every time I come down here and walk around the trail, I just feel absolutely refreshed and ready to go. It just adds to my quality of life all over."
Warnock says her brother is nothing if not committed to his goals. Last year he set out to walk the loop 200 times.
"Ron's thing last year was if he died in a plane crash before he met his 200, I was to take his ashes in an urn around the trail."
On National Aboriginal Day, Ostrom plans to walk the trail five times.
