What does walking Shinnecock do to a 50-year-old body?

Shinnecock is a walking-only links course with significant elevation change and firm, uneven lies. For a 50-year-old golfer, that combination loads the lumbar spine, hips, and posterior chain far more than a flat cart course. Most golfers feel it as next-day stiffness through the low back, hip flexors, and calves — recoverable with the right post-round protocol.
