Robin Calvert was never expected to live past childhood. Born with a rare heart defect and raised in a home that rejected modern medicine, he was taught to rely on faith, not doctors. But somehow, he survived. Then he kept surviving. What followed was a life both extraordinary and painfully real. 'Riding Thumper' is the honest and inspiring story of one man's lifelong battle with illness, told with clear-eyed humor, emotional depth, and an unflinching look at what it means to live truly. From childhood in the mountains of South Lake Tahoe to a lifetime spent pursuing passion, purpose, and independence, Robin brings readers into a world shaped by hardship, resilience, and small victories that mattered more than they should have. Through decades of surgeries, setbacks, and personal loss, Robin never gave in to despair. Instead, he sought meaning through theater, love, family, and the freedom of a motorcycle ride across the country. This is not a book about dying. It is a book about living while knowing what's coming. It's about holding on to humor, finding peace in unexpected places, and pushing forward when the world quietly expects you to stop.
