TWIN FALLS — He’s done it before, and on the longest day of the year, Miles Daisher says he’ll do it again.

Daisher, a Twin Falls resident, plans to reclaim his unofficial record for the most human-powered BASE jumps off the Perrine Bridge in 24 hours. The professional BASE jumper will take to the air at 10 a.m. Tuesday, weather permitting, and complete nearly four jumps per hour to beat the 61-jump record held by rival Danny Weiland.

September usually has the best weather for BASE jumping, but the solstice will have the most daylight — though Daisher intends to continue his jumps after dusk.

“I’ve got plenty of Red Bull,” he said. “I can keep going all night long.”

And he’s confident that while his 57-jump record in 2007 got cut short by high winds, this time will be different.

“I know that the universe shall provide,” Daisher said. “You gotta believe.”

The chances are it won’t be an officially recognized world record — though Daisher will look into that. For now, he’s focused on preparing for the jumping and hiking aspects. Sixty jumps and trips up the canyon wall will push him past the distance of Mt. Everest — so his goal is at least that.

“It would be nice to beat Danny Weiland,” Daisher said.

Weiland set the unofficial world record on Sept. 16 after Daisher had held the title for more than 10 years.

“It’s a physical feat not only to climb out of the canyon, but to jump off again,” said Melissa Barry, director of Southern Idaho Tourism.

Barry’s agency is one of a few local sponsors for the jump — and Daisher’s parachute will sport a Twin Falls-themed logo she hopes will spread a message to people watching the jumps online.

Daisher is sponsored by Red Bull, and a member of the Red Bull Air Force — a specialized team of expert pilots. As of Tuesday, he had made 4,460 lifetime jumps, the last being in Petra, Jordan.

“That was like an ultimate rush,” he said.

When he isn’t BASE jumping or skydiving, Daisher might be found feeding goats at his Twin Falls home, hiking or mountain biking.

Wind gusts should be less than 20 mph for his BASE jumping — conditions he can test with an anemometer, but will probably use his own “built-in” gauge. He may start jumping a day early if conditions appear more favorable.

Spectators wishing to view BASE jumping can watch from the I.B. Perrine Bridge or the nearby Canyon Rim Trail. Daisher is also taking sponsors willing to donate to the Magic Valley Trails Enhancement Committee. Information is available at

“Some people think I’m crazy, he said. “But if you’re not doing what you love, then I think you’re crazy.”
