Breaking Assumptions
One world record - Sixty Three Triathlons
A lifetime of proving assumptions wrong.
the book
Most people see the finish line.
They often don’t get to see the miles before it.
Breaking Assumptions follows Tom Scheer's journey through three years of 70.3 triathlons on a quest to break a World Record — but the real race began decades earlier.
Each race tells a different story: childhood, identity, adversity, leadership, family, resilience, and the moments when life challenges the assumptions others place on us.
