Since retiring, she and her husband Jim have focused on cycle touring, and trail advocacy. They have explored many of the destination trails in Europe and North America, studying various approaches to safety, sustainability, and bike-friendliness.

Ryan Gravel

Ryan Gravel, AICP, LEED AP, is the founding principal of Sixpitch and creator of the Atlanta Beltline, the reinvention of a 22-mile circle of railroads that began as the subject of his master’s thesis.  A designer, urban planner, and writer, he is increasingly called to speak to audiences across the world on topics as wide ranging as transportation, public health, affordable housing and urban regeneration.  Ryan lives with his family in Atlanta.  

Atlanta Beltline is changing both the physical form of his city and the decisions people make about living there. Now a $4 billion public-private investment in the early stages of implementation, the project’s health and economic benefits are already evident through record-breaking use of its first section of mainline trail and $3.1 billion of private sector redevelopment since 2005.

Ryan has received numerous awards and press related to his work on the Atlanta Beltline and tells his story internationally, but an essential aspect of his work is yet to come. Alongside project work at Sixpitch and research on similar “catalyst infrastructure” projects around the world, he makes a compelling case about what this movement means and why it matters. In his book“Where We Want to Live,”, Ryan investigates the cultural side of infrastructure, describing how its intimate relationship with our way of life can illuminate a brighter path forward for cities.

Matthew Schrager, PhD

Matt is Professor of Health Sciences at Stetson University.  He teaches courses in human anatomy/physiology, the physiology of aging, exercise physiology, biomechanics and research methods. His research focuses primarily on aging, bioenergetics, and functional capacity. He has a secondary research focus on the physiology and biomechanics of mobility and human performance. Matt holds a Ph.D. in Kinesiology (Exercise Physiology) from the University of Maryland and resides in DeLand, FL.

In his aging research, Dr. Schrager analyzes large-scale databases through the National Institute on Aging, and he has published with Stetson students research on blueberries as a potential countermeasure to the functional effects of aging. He is also interested in the role that the “built environment”/bicycling infrastructure has on encouraging or inhibiting physical activity. He has a wide range of relevant research interests including understanding and combatting age-related changes in performance and health. 

He recently took a sabbatical in the town of Haarlem near Amsterdam where he learned much from the Dutch cycling culture and infrastructure. He traveled to Copenhagen to meet with Mikael Colville-Anderson, CEO of Copenhagenize Design Co. and author of the book Copenhagenize, The Definitive Guide to Global Bicycle Urbanism, who recently lead a panel on  “How to Copenhagenize Miami” held at The Idea Center at Miami Dade College. Matt is continuing to communicate with him on ways to make DeLand and other central Florida cities more bike-friendly.

Bill Stanley

Bill’s earliest memories of cycling involve being launched down a hill multiple times by his older siblings, on a bike that was much too large for him to reach the pedals at the bottom of the downstroke. Fortunately, his sixty years of riding since then have been less hazardous.

After completing his bachelor’s in Technical Theatre, Bill (like most thespians) went on to employment in the performing arts, retail, construction, food service, manufacturing, and then information technology. 

In 2008, Bill retired from his position as Manager of Database Administration at Coty Inc. to spend his time riding and sailing on his and his wife, Laurey’s, 34-ft Gemini catamaran, Solstice, on the Chesapeake Bay. Within a few years, they upgraded to a 54-ft pilot house trawler, Ursa Major, and became official live-aboards.

A late start south in 2014 was the inspiration needed to spend a winter on the St. Johns River. During that winter, they happily volunteered to be marina hosts at Hontoon Island State Park and returned to host again for the winter of 2015-2016, with Bill driving the park’s ferry while Laurey worked in the park store.

Bill and Laurey “swallowed the hook” in 2016 with the purchase of a house in DeLand, Florida. Laurey accepted a position on their neighborhood’s HOA, while Bill has since picked up a part-time job at a local bike shop (to help support his cycling habit).

Bill is a big fan of long group rides and has completed the RAGBRIA, Great Allegheny Passage, and C&O Canal Trail, as well as the New River Trail and the Erie Canal Trail. Bill feels that the St. Johns River-to-Sea Loop has the potential to be one of the best long rides in the USA. Its 260 miles are easily covered in five days, giving riders two days to get here and two days to get home on a week off from work. What could be better than driving out of the winter cold of the Midwest to spend a week riding along the Atlantic coast and witnessing the ‘real Florida’ of the St. John’s River Valley?
