George Meegan's 1977-1983 trek from the southern tip of South America to Alaska covered roughly 19,000 miles on foot the entire way, still recognized as the longest unbroken walking journey ever recorded.
Even with all that scheduled treadmill time, astronauts still lose bone density in space. The impact forces from walking in microgravity are measurably lower than walking on Earth, which seems to be part of why exercise alone doesn't fully offset the loss.
