Choosing your 2027 race
Set the goal first, then the date
A first marathon takes 16 weeks, a half 12, a 10K 8. Count back from the race to know when the plan starts — and check it fits your calendar.
Register early for the majors
Boston, Chicago, New York and Peachtree run on qualifying times, lotteries or waves and fill months ahead. RunRun race pages show registration dates.
A tune-up race 6 to 8 weeks out
A 10K before a half, a half before a marathon: the tune-up validates your pace and builds confidence. Find it in the same month of the calendar.
Check the course and the weather
Chase a PR on a flat course in spring or fall. Pick a trail by its climb: 13 miles with 2,500 ft of gain is a different race from 13 miles with 6,500 ft.
Keep the holidays for fun runs
Turkey trots, jingle bell runs and night races keep you moving without pressure before the 2027 build starts.
