Whereas it took the last official runners 30 minutes to cross the starting line last year, this year it will take fewer than 10 minutes for each wave to cross. It is important to note that the anticipated net difference in this method versus previous years' 'one gun, one start' is only about 10 minutes, meaning the last runner will be crossing the starting line this year at 12:40 p.m. as compared to 12:30 p.m. last year.
