Ultrarunner Harvey Lewis reaches the end of Lazarus Lake’s endless backyard

Harvey Lewis, a 47-year-old Ohio ultramarathoner, won the last-man-standing Big Dog's Backyard Ultra race after running the approximate distance between San Francisco to LA

The pleasures of winning a world championship can sometimes be small, but immediate. The evidence is plain in the smile of ultrarunner Harvey Lewis at 6.59pm on Wednesday 25 October. Lewis has just won the 2023 Backyard Ultra World Championship, but what appears to be of greater immediate relief is that after 450 miles, and for the first time in 108 hours (four and a half days), Lewis will not have to run four and one sixth miles (6.7km) at the start of the next hour.

Ultrarunners like Lewis compete in ultramarathons, or ultras. Any footrace longer than a traditional marathon (26.2 miles, or 42.2 km) is considered an ultra, although within that designation there exist multitudes - in New York City alone, ultras can range from pop culture-themed 28-mile events to epic journeys thousands of miles in length.
