2014 Chicago Marathon to guarantee spots for some runners

January 16, 2014 3:40:49 PM PST
Some big changes are coming to this year's Chicago Marathon. Runners will be guaranteed spots in the race, but only if they have participated in a marathon within the past two years and under certain conditions.

Men must have completed a marathon in less than 3 hours and 15 minutes. Women must have finished in less than 3 hours and 45 minutes. A lottery will be held for non-guaranteed spots.

Registration for the marathon begins March 5.
