🧛 THE 2026 H³ SWAG HAS RISEN.

This year’s vampire theme is coming to life, and the swag has some serious bite.

Sink your teeth into this year’s H^3 race gear and finisher medal, featuring our bloodthirsty vampire design. Because if you’re going to survive 13.1 miles, you deserve something worth showing off afterward.

The swag is ready. The vampires are waiting.

Register for H^3 and come run with the creatures of the night. https://tr.ee/w0ORBxhpBq

That awkward moment when your running buddy asks if you registered before the price increase… and you suddenly remember you forgot. 😬

Don’t be THAT runner! Register for the H^3 Halloween Half & 5K and the Annual F^3 Half Marathon & 5K before prices go up after Sept. 25, then tell your friend to do the same!

Your future self (and your wallet) will thank you. 🧛🏃‍♀️

This Halloween, trade your cape for running shoes and sink your teeth into 13.1 miles at the H³ Half Marathon. 🩸

Come for the miles.
Stay for the Halloween vibes.
Leave with the bragging rights.

Because anyone can run a half marathon, but it takes a special kind of runner to do it with a little bite. 🦇

Nobody wakes up in January ready to run 13.1 miles.

The finish line is built one alarm, decision, and run at a time.

The runners who cross the F^3 finish line next winter are laying the foundation right now.

A season of commitment, growth, and becoming the runner you want to be.

🏃 What are you training for this year?

Every finish line has a starting point. If you want to run the 2027 Chicago Half Marathon & 5K, yours starts now.

The miles you run in the sweltering summer months become the strength you rely on in January when the wind whips off the lake as temperatures drop to single digits.

Who’s building toward their next big finish?

has done it again! 🏃‍♂️🔥

ICYMI....

When Joabe ran with us at the 2026 F^3 Half Marathon and broke a Guinness World Record by running in slides in 20° weather. (pictured with our race director!)

Then, in March, he broke another record by being the fastest person to visit every Chicago subway station.

Now he’s broken another record by officially running EVERY street in Chicago.

We are so proud to have him as a member of our running community and a citizen of Chicago!

Congratulations, Joabe!
