“I’m exhausted, in pain — and happy.”

Those are the closing words in Erik Pohlmann’s video that recaps his 20-hour, 13-minute race to summit the four Boise-area Grand Slam peaks in less than a day, an unofficial record.

Pohlmann rode his bike between the trails and up as many of the peaks as possible: Kepros, Lucky Peak, Heinen and Cervidae. He covered 81 miles by bike and 12 by foot. He climbed 12,000 feet by bike and 3,500 by foot.

He started his ascent of the painfully steep Cervidae at 11:50 p.m., reached the summit by foot at 1:12 a.m. and returned to his truck parked along Idaho 21 at 2:48 a.m. He had left the truck at 6:35 a.m.

“I thought it was fantastic,” Pohlmann, of Boise, said. “Toward the end, you’re always living in the pain, but the next day you wake up and reflect back on it and you think: ‘That was awesome. I want more.’ Overall, I really enjoyed it. It’s under your own power, it’s peaceful.”

He began by riding from the Boise River Wildlife Management Area office on Idaho 21, back toward Boise and out Blacks Creek Road to Kepros. He rode to the top and back down, then back out Idaho 21 to catch the East Highland Valley trail to Lucky Peak. He rode down a different route to end up back at his truck, where he had leftovers stashed for lunch.

He went to Hilltop Station for a burger instead.

He reached a Heinen trailhead at 5:11 p.m. and needed 3 hours and 15 minutes to reach the top by foot. He got soaked by thunderstorms along the way.

He hiked most of Cervidae, too — and completely in the dark.

Why did he choose such an extreme goal?

“I’ve struggled trying to answer that myself,” he said. “I have a lot of adventures that I go on, climbing peaks. I typically like doing stuff that people have not done — that’s the inherent adventure I was born with.”
