News Finding: At the other end of the range studied, the age of the top 1,000K runners remained unchanged; the leading women and men are an average age of 42 and 49, respectively.
Paper Finding: In 1,000 km, most female runners were in age group 35-39 yrs, whereas most male runners were in age group 55-59 yrs.
News Context: Between 1977 and 2012, the age of the year's 10 fastest men decreased from 35 to 33. At the other end of the range studied, the age of the top 1,000K runners remained unchanged; the leading women and men are an average age of 42 and 49, respectively. The trend noted at the shorter end of the ultra spectrum has, if anything, accelerated since 2012, the last year the analysis included.
Paper Context: In 100 km and 200 km, most of the runners were recorded in the age group 45-49 yrs for both genders. In 1,000 km, most female runners were in age group 35-39 yrs, whereas most male runners were in age group 55-59 yrs. The athlete's ages of the ten fastest women ever were 40 ± 4 yrs (50 km), 34 ± 7 yrs (100 km), 42 ± 6 yrs (200 km), and 41 ± 5 yrs (1,000 km) (Figure 4 ).
