Halloween Leftovers – 5K, 10K, 10-Miler, Half Marathon

Halloween Leftovers – 5K, 10K, 10-Miler, Half Marathon takes place in Long Beach on November 1, 2026, with four distances packed into one morning. The half marathon (13.1 miles) and the 10-miler both go off at 7 a.m., then the 10K and the 5K follow at 7:30 a.m., so you pick the distance that matches where you are in your season.

This is a road event, and it works well as a late-fall checkpoint: race the half as a fitness test before a winter marathon, or use the 10-miler as a hard, supported long run. If the half is your target, eight to twelve weeks of steady running with one weekly long run stretching toward 11 miles will cover it. The 10K and 5K ask for less mileage and more time at threshold pace, and the later start makes them the easier option if you want to sleep in another half hour.
