Prabhupada was walking on and on very fast.

Yamuna : In that early San Francisco period, Srila Prabhupada allowed us to spend time with him all day and into the night, but morning walks were one of the most relishable, glorious times with him. I generally wanted to be on the morning walk. One of the other devotees and I used to get up at two in the morning, pick flowers in Golden Gate Park, make garlands for Srila Prabhupada, present them to him, and go on the morning walk. Those moments in the park were always very special for us, walking next to our spiritual master, trying to chant Hare Krishna just as he chanted Hare Krishna. The morning walks were japa walks, and he walked briskly, chanting Hare Krishna with his hand in his bead bag. He walked like a young man of twenty-five. The first day I went I was wearing wooden yogi shoes, and my feet bled because Prabhupada was walking on and on very fast.
