It is almost impossible to read a memoir or biography of a Victorian writer without coming upon the inevitable walking statistics. Even [John Stuart] Mill, that effeminate “logic-chopping machine”… walked fifteen miles three days before his death at the age of sixty-seven, a modest record compared with [Leslie] Stephen’s grandfather, who celebrated his seventieth birthday by walking twenty-five miles to breakfast, then to his office, and home again the same day. Fifty miles a day was about the average for the “Sunday Tramps” organised by Stephen.
