<p><strong>Changing Standards</strong><br><br>

April 19, 1897—<b>OPEN</b> Fifteen men run the first Boston Marathon, open to any male 19 or older.<br><br>
1970—<b>4:00</b> To control crowds, the first qualifying standard is instituted. "This is not a jogging race," say organizers.<br><br>
1971—<b>3:30</b> BAA lowers the time restrict field to 1,000; 1,067 enter.<br><br>
1972—<b>3:30</b> Women, now allowed officially to enter, are kept to same time standards.<br><br>
1977—<b>3:00</b> New time is instituted for men 39 and under.<br><br>
1980—<b>2:50</b> Due to record number of entrants, standards tighten for men 19-39, 40+ (3:10), and women (3:20).<br><br>
1981—<b>3:20</b> New standard for men 50-59; men 60+ and women 40+ get 3:30.<br><br>
1984—<b>3:50</b> As the ranks of "masters" women rise, new time set for women 60+. (Women 50-59 must run 3:40.)<br><br>
1987—<b>4:00</b> The BAA eases times for all women (from 3:30 for those under 40 to 4:00 for 60+) and men 18-39 (3:00).<br><br>
