Ultra-marathons have a long history (‘No limits’: how the marathon was overtaken in sprint to stretch horizons, 19 April). In 1809 Robert Barclay Allardice walked a thousand miles in a thousand hours on Newmarket Heath, for a bet of a thousand guineas. And then in the 1880s there were the “Wobbles”, six-day indoor races, at the agricultural hall in Islington, ending in a record of 623 miles, which, like the hall, still stands. Finally, there were in 1928 and 1929 CC Pyle’s Trans‑American races on which my novel Flanagan’s Run was based.

• Talking of distance running, do not forget the Buddhist “marathon monks” of Mount Hiei in Japan. They run between 40km and 84km for 100 consecutive days, sometimes twice in a year, for seven consecutive years – on mountain paths, wearing straw sandals and robes.
