Philippe Cresik’s smartwatch GPS data gives clues to runner’s death

Philip Kreisik, an avid trail runner whose disappearance last month called off a week-long search and rescue effort, was likely to begin his trail run at Pleasanton Ridge Regional Park, an official said Tuesday. He died four hours later.

Although Krei began to advance his route at an accelerated clip, he eventually slowed down dramatically and veered off course.

He may have been “suffering from heat stroke, or having some sort of delirium” in his final moments, Sgt. Alameda County Sheriff’s Office spokesman Ray Kelly said Tuesday, based on a review of GPS data from Cressick’s smartwatch.

While a coroner’s official report is still not complete, the data – which was first reported by The San Francisco Chronicle – suggest that Cressik died before any legion of professional and volunteer explorers arrived, Kelly said.

Cressick, who left his phone in his car at the Moller Ranch staging area on July 10 when he asked his wife for a one-hour hike, seemed to have started hitting his mark at high speed Is. About 12 mph – about 5 minute mile pace.

But after about 45 minutes, Kreisik’s pace slowed down to a light jogging pace. Kelly said she picked up speed again for a while, but after being in the park on a scorching summer day for more than two hours, she slowed to walking, and her movements became erratic, Kelly said. said.

Kelly said the watch’s data had been reviewed by experts, who believe Cressik eventually landed in a crisis.

“Since GPS data starts with circles and circles and circles, and there’s no rhyme or reason to it, it’s very sporadic and it’s a very confusing and very distracting type of data,” Kelly said. “He didn’t take the whole path, he took a part of that path. He deviated from his plan.”

Cressick started on his trail run at around 10:49, and based on his running experience and starting pace, Kelly said it was very likely that Cresick could have been back on his car by noon if the run was clearly was planned.

“He definitely finished,” Kelly said. Officials believe Cressick was intending to take a roughly 8-mile route along a loop trail in Park, outlined on his Strava fitness app, which he was unable to complete because of his running. Should have taken about an hour.

Kelly said his wife, Zhen Yao, told Kreisik that he had gone missing at around 2 p.m. that evening and that searchers were looking for him until that evening.

Search efforts mounted, and law enforcement teams used night flights with drones, scent dogs, and heat signature sensing technology to try and locate him. Thousands of people from the Bay Area and beyond eventually helped find Cressick on August 3, when a volunteer searcher found his body under a tree, a short distance from the Game Trail.

Officials had previously told this news organization that the watch Kresik was wearing did not have GPS capability. Kelly said officials initially had mixed information about what type of watch Kreisik had. It was a Suunto branded smartwatch with GPS capabilities, although it did not track biometric data, such as his heartbeat.

Kelly said Kreisik covered a total of 9.62 kilometers, or about six miles. While there is no biometric data from the watch, Kelly said officials believe Cressik died shortly after recording his final movements, about four-and-a-half hours after starting the exercise.

A preliminary autopsy completed earlier this month showed no signs of foul play, Kelly said, and combined with clock data, it indicates that Kreisik may have suffered from a “medical incident” during his run. is likely to.

“There was no sign of major broken bones or significant traumatic injuries that would cause you to become disabled or non-mobile,” Kelly said.

“The clock data is very important and it is certainly helpful for investigators and the coroner’s bureau and family to give us a timeline and a better understanding of the events that happened at the end of Philip’s life,” he said. “In that regard, it’s very helpful and helps to put your mind at ease about any other possible scenario.”
