Passion Drives Performance
We love what we do, and that energy fuels a learning environment that’s inspiring, committed, and alive.

Growth Through Challenge
We embrace discomfort as a necessary part of learning — and help our skiers do the same.

Our Story
Inside Edge Coaching was founded by Joshua Duncan-Smith and Guy Dale, two internationally respected coaches who share a deep commitment to elevating the sport of skiing through science, skill, and authentic connection. After years of working together across Canada and New Zealand in the Whistler Blackcomb snowsports school and at the prestigious Rookie Academy in Treble Cone their aligned philosophies and complementary experience led them to create a coaching experience unlike any other.
​
Together, they bring decades of global experience at the highest levels of instruction, performance coaching, and instructor education.
​
Josh began teaching in the Swiss Alps in 2011 and quickly discovered his vocation in ski instruction. He now holds top-level certifications from Italy (AMSI), New Zealand (NZSIA), Canada (CSIA), Ireland (IASI), and with the Professional Ski Instructors of Europe and Canada (PSIE & PSIC). Josh is a senior examiner and current Demo Team member for both the NZSIA and PSIE. As a global ambassador for Original+, Carve Sport, Zip Fit, and SHRED Optics — and with a growing audience through his YouTube channel Josh Duncan Smith brings technical precision, elite-level insight, and a tireless passion for helping skiers unlock their full potential.
​
​
Guy discovered his love for skiing on the dry slopes of the UK, a foundation that sparked a global coaching journey spanning Europe, Canada, Japan, China, Australia, and now New Zealand. Based in Whistler, he is a CSIA Level 4, APSI Level 4, CSIA Level 4 Examiner and a two-time Interski Team member for the CSIA, having represented Canada at Interski 2023 in Levi, Finland, and set to do so again in 2027 in Vail, USA. He also serves as Chair of the CSIA’s Technical and Educational Committee (TEC) and is a camp leader with extensive experience running training programs in Japan, Australia, and beyond. Currently, Guy is a global ambassador for Head Skis, Auclair Gloves, and Varga Goggles. With a background in racing and leadership roles at Mt. Buller and Whistler, he brings a uniquely versatile and athlete-focused approach to development.
​
​
Inside Edge Coaching was born from a desire to leave a meaningful mark on the ski industry — to offer something different. In a market where technical depth and personal connection are often treated separately, Josh and Guy believed in a more integrated approach. They saw an opportunity to create something truly powerful.
​
Together, they’ve built a coaching philosophy that’s precise but personal, demanding yet supportive. At Inside Edge Coaching, you’ll find an environment where trust is built first, connection is central, and progress is inevitable — turn by turn.
Meet The Team
Inside Edge Coaching aims to be the world’s leading ski coaching community — where science, passion, and connection inspire every skier to reach their highest potential. We create inclusive, science-driven experiences that help skiers transform, learn, and grow while igniting lifelong passion.

Coaching Philosophy
At Inside Edge Coaching, we believe the best learning happens when skiers feel connected, valued, and challenged. Our philosophy centres on understanding the whole skier — their physical mechanics, mental approach, and emotional motivation.
​
Grounded in the latest research on biomechanics and skill acquisition, we tailor our coaching to each group’s needs, blending scientific precision with an intuitive feel for the sport. We prioritise building strong relationships within our groups, because we know that connection fosters motivation and unlocks deeper learning.
​
We embrace a “connect before we correct” mindset — guiding athletes through progress with empathy and trust rather than judgment. By nurturing this supportive culture, we empower skiers to grow confidently, sustainably, and with lasting passion.
