“In her book Across the Line, Sue Reynolds dares to ask a bold question: What would happen if an ordinary age-group athlete in her seventies trained with Olympic coaches? The answer takes her on an extraordinary path filled with breakthroughs, setbacks, and powerful lessons in resilience, grit, and self-discovery.  Candid, funny, and deeply inspiring, Across the Line is more than a story about sport. It’s a story about daring to dream bigger, finding strength in unexpected places, and stepping into the question, “Why not me?” Dive into Sue’s journey to explore what elite coaching taught her about life and sport, and discover how her story can inspire all of us, no matter our age or starting point.”

– Rich Soares, triathlon coach, Grit2Great Endurance Podcast

“Across the Line shows that you can’t extract the athlete from the history they bring into the coach-athlete relationship…The book explores what happens when the same mental models that make her so incredibly capable blind her—and, more importantly, her coaches as well—to a dangerous level of exhaustion. The book reads like a memoir but also a method. Sue lays out a model of high performance that may be equally applicable to any athlete in any sport, and to anyone striving for excellence in the parts of life worth everything—being a parent, teacher, or coach.”

– Maarten Bout, Age-Group World Silver and Bronze Medalist, 8x National Champion, 2022 Triathlete of the Year

“Across the Line describes how Sue Reynolds stepped up to another level of training, learning how to balance multiple workouts with proper recovery and how to run by feel…[It is] an important book for coaches, athletes, and high performers in any field to read as it explores the fine line between pushing hard and pushing too hard…A lovely valuable book.”

– Bobby McGee, elite running coach

“Sue brings the same enthusiasm, honesty, and work ethic to her book as to her training. Across the Line is a really insightful piece of storytelling to life…I loved reading Across the Line—it has so many fascinating aspects lying within.”

– Darren “Daz” Smith, elite triathlon coach for Olympic medalists and world champions, including Daniela Ryf, Anne Haug, Lisa Norden, Vicky Holland, and Sara True

“Across the Line is an exposé of the benefits and potential consequences of employing the ‘whatever it takes’ mentality to train and compete as is promoted in the world of elite athlete development. Sue Reynolds recounts in this book her courageous and harrowing journey into and through the high moments and darkness that can befall an athlete pursuing mastery at their craft."

– Jeff Troesch, internationally-renowned sports performance consultant, author of One Day Better

“Sue Reynolds lost over 150 pounds, took up triathlon in her sixties, and became a world champion…She wanted to answer a question most age-group athletes never dare ask seriously: what would happen if an ordinary amateur trained with the same expectations, the same daily habits, and the same meticulous standards as an Olympic-level athlete? That question took her to the World Triathlon Championships in Pontevedra in 2023, where she led the swim—alone, three minutes clear, asking an official which way to run because she had never been at the front before. It eventually took her somewhere she hadn't planned to go at all. Her new book, Across the Line, covers all of it.”

– Simon Ward, tutor and coach educator, British Triathlon High Performing Coach Programme, and host, Be Battle Ready Podcast

“Across the Line is a must read for anyone who shares a passion for the process of success and pushing yourself to the limits…This book is relatable for coaches and athletes…a must read for every triathlete!”
