She said she had last heard from David as he entered the Knoydart Forest and told her he would likely not have signal for a while.
Jade and his friends were tracking him via GPS but after a period of time passed without hearing from him, they decided to alert the police.
A friend was in the area waiting to see him pass, but Jade decided to drive up to the location.
“On the drive up, I received a call from the police saying that the case was going to be escalated to David being a high-risk missing person,” she said.
“Shortly after that I got a call to attend the police station in Kyle of Lochalsh where they delivered the news.
“Then the next morning his friends and I went to the mountain rescue base in Kintail where we identified him.”
A spokesperson for David’s running club said they were “deeply shocked and saddened” to hear about his death.
“David was an immensely talented runner and a wonderful person who will be sadly missed by all who knew him,” they added.
