The busiest weekend in Arizona is December 12 and December 13, with 3 10K races on those two days, and the single busiest day is Saturday, December 26 with 3. Another 1 fall on a weekday, which is worth knowing if you are traveling for one.
As early as you can. 2 of these December 10K races already have a price increase on the calendar, and 8 are open for entry right now.
The typical entry is $30, with paid entries running from $30 up to $54.99. Entry fees climb as race day gets closer, so the same race is usually cheapest the week it opens.
November and January sit either side of December, which is where most people look next when a date does not fit.
