About this race

‍ SEASONAL CONFUSION RUN

5K • 10K • Half Marathon • 5K HYBRID

Sunday, September 13

5000 E Ocean Blvd, Granada Beach | Long Beach, CA

Sweater or bikini? Iced coffee or pumpkin spice?

It’s California — we’re officially in a state of seasonal confusion.

The Seasonal Confusion Run celebrates that weird in-between moment when summer won’t let go, fall is pretending to arrive, and the weather absolutely refuses to cooperate.

Come run the coast in whatever makes sense to you — hoodie, tank top, or beachwear encouraged.

 

RACE DAY SCHEDULE

• Half Marathon: 7:00 AM

  Half Marathon Hybrid: 7:00AM

• 5K & 10K: 8:00 AM

• 5K 10K Hybrid: 8:10 AM

Same-Day Registration & Bib Pickup: Opens at 6:00 to 8:10  AM

 

NEW:  HYBRID CHALLENGE

Want more than the 5K, 10K, Half Marathon? Take on our Hybrid Challenge, combining your run with a finish-line functional fitness challenge.

Everyone starts together and completes the normal  course.

When Hybrid runners return from the course, they DO NOT cross the finish line yet. Instead, they head directly into our TFL Hybrid Zone to complete:
