Greg Siple, co-founder of Adventure Cycling, retires

Published January 19, 2017

MISSOULA, Mt. (BRAIN) — Greg Siple, Adventure Cycling Association’s co-founder and art director of 40 years, will retire on Jan. 29. Siple, who will turn 71 on that day, will retain his role as art director in emeritus status.


Over the past five decades, Siple has dedicated his career and volunteer time to promoting and inspiring people from all walks of life to use the bicycle as a means of travel and adventure. Along with his father, Charles, Siple founded the Tour of the Scioto River Valley, a precursor to today’s mass bike events.

With his wife, June, he completed Hemistour, the first bicycle tour from Alaska to Argentina, which was featured in the pages of National Geographic in 1973 and could be called a foundational ride for the current bikepacking and touring boom.

He also co-founded Bikecentennial ’76, now Adventure Cycling Association, the largest cycling membership organization in North America, with his wife and Dan and Lys Burden.

“Greg is one of the four founders of Adventure Cycling, and the only one still on staff after all these years. We wouldn’t be where we are today, and neither would bicycle travel, without Greg’s quiet, effective commitment to the mission of Adventure Cycling,” said Jim Sayer, Adventure Cycling's executive director.

For almost 40 years, Siple has designed and contributed to Adventure Cyclist magazine. He recently co-authored the book America’s Bicycle Route: The Story of the Transamerica Bicycle Trail, published in 2016 and currently in its second printing.

“As the person who has worked most closely with Greg over the past 22 years, I'm having a hard time imagining life at Adventure Cycling's headquarters without his daily presence. His dedication to bicycle travel and cycling in general will be sorely missed, as will his good cheer and sense of humor,” said Mike Deme, Adventure Cycling's design and media director.

Siple plans on continuing his touring ways and will be doing so with his wife, June, on a pair of Brompton folding bikes.

The association will host an open house on Feb. 3 from 5 to 8 p.m. at Adventure Cycling’s headquarters to celebrate Siple's career as well as the completion of the newly remodeled east wing of the organization’s building.
