North Shore rescuers have responded to a record number of calls this year, prompting a message of caution from the team.

Doug Pope, North Shore Rescue search manager, said being physically prepared is crucial before heading out to hikes like the Grouse Grind.

"It's an arduous hike and once you get up there, you're halfway up … going down really isn't a good option so you’re kinda stuck there. So you’re a lot better off preparing by going on less arduous hikes first,” he said.

Siblings Sam and Andrew Boonngum prepared to hike the Grind Sunday, and said they were aware of the challenges that lie ahead.

"Despite how many people talk about the fact it's a grind, it's actually that hard and people don’t take that seriously until they’re halfway up and they realize that ‘This isn’t that easy at all,’" Andrew said.

Pope said rescue crews are prepared for 80 rescues in July, much higher than the 60 rescues at this same time last year. Seventy-three rescues have already been completed this month.

"It's really difficult to sustain this many calls on an ongoing basis if this is the new norm,” he said.

Hikers should pack the essential materials to prepare for the worst case scenario.

"Things like a map, a compass, a GPS, some kind of communications tool to have with you," he said.

It’s also a good idea to leave a trip plan with a family member or friend detailing the start and end of your route, and expected timing of your excursion.

After an eight-year-old boy and his father were rescued from Hanes Valley last weekend they had a special message of thanks for the rescuers. The pair gave a handmade thank you card and a donation to the team.

“It kind of makes it all worthwhile when we get that kind of acknowledgement,” Pope said.
