Mean Girls 5K, 10K & Half Marathon

On Mean Girls Day, October 3rd, 2026 he asked you what day it was. You said it’s October 3rd.

Now lace up and run.

Welcome to The Mean Girls 5K, 10K and Half Marathon, a pink powered comedy fueled tribute to the most quotable high school ever. This event transforms the LA River Path into North Shore High where every runner is either trying to make fetch happen or survive gym class without being personally victimized by Regina George.

Presented by Jed and Ted’s Excellent Races.

Wear pink if it’s Wednesday. Wear sweatpants only if it’s Saturday. Do not wear army pants and flip flops unless you want everyone else to buy army pants and flip flops.

This is your chance to run like you’re late for Calc, dodge Regina’s bus, and earn a medal pretty enough for the Spring Fling Court.

Choose your challenge:

• The Burn Book 5K - A fast and funny out and back perfect for anyone who wants to run, walk, gossip, or talk about how butter is a carb.
• The Glen Coco 10K - Six point two miles of pure candy cane energy. You go Glen Coco. Treat yourself and your friends. None for Gretchen Wieners.
• The Full Plastics Half Marathon - Thirteen point one miles of pure drama control. Stay hydrated. Stay cute. Try not to start a three way call attack. Cross the finish feeling like the new Spring Fling Queen.
• The Multiverse Lunch Table Dash (Virtual) - Run from anywhere. Work. School. Your bedroom. Africa.
