In 1980, in what was termed the Marathon of Hope, Terry Fox, who had lost a leg to cancer and so ran with one artificial leg, attained 5,373 km (3,339 mi) of his proposed cross-Canada cancer fundraising run, maintaining an average of over 37 km (23 mi), close to the planned marathon distance, for each of 143 consecutive days.
However, beyond a certain point, negative consequences might occur. Older male runners (45-55) who run more than 40 miles (64 kilometers) per week face reduced testosterone levels, although they are still in the normal range. [34] Running a marathon lowers testosterone levels by 50% in men and more than doubles cortisol levels for 24 hours. [35]
A half marathon is a road running event of 21.0975 kilometres (13 miles 192.5 yards)—half the distance of a marathon. [1] It is common for a half marathon event to be held concurrently with a marathon or a 5K race, using almost the same course with a late start, an early finish, or shortcuts. [2]

At exactly four laps of a normal 400 m track, this distance is raced as a near replacement for the mile (it is, in fact, 9.344 m, about 30.6 feet, shorter; however, it is still colloquially referred to as "the mile"). The 1600 meters is the official distance for this range of races in US high schools. While this race is rarely run outside high ...
