Gregg Alan Walchli died on November 6, 2025, at home with family after a courageous 10-month battle with Cholangiocarcinoma (bile duct cancer). Gregg grew up in Hermiston Oregon and attended Hermiston high school where, in 1980, he was a part of the 4×400 relay team which set the school record – which stood for 30 years. Gregg studied Accounting & Finance at the University of Oregon. Eugene. He was a valued employee for over 25 years at Integrated Real Estate in Seattle. While running at lunch time on the Seattle waterfront, he met his wife, Cheri Pompeo. With Cheri, Gregg ran marathons on 7 continents, 3 times around all 50 states, and all the provinces and territories of Canada. He completed over 333 marathons in over 30 countries before a knee injury limited him to shorter distances. He was an amazing travel planner and arranged for and accompanied Cheri to 60 countries for marathons. Gregg’s passion for the Rolling Stones complemented his running passion. He became a fan as a preteen and attended every concert available to him. Many times, these coincided with marathon trips in the US and Europe. Gregg is survived by his wife, Cheri Pompeo, sons Mick and Dylan Walchli, stepchildren Maureen Gillis, Ian Gillis and Marissa Moon, sisters Cheryl Walchli and Diane Fetterhoff, brother Phillip Walchli and mother Marge Walchli and several nieces and nephews.
