How It Works

BREAKING: Local eyewitnesses have just reported a rare Summer GRIT sighting, a comet-like run challenge only seen twice a year in the wild.

So real that it’s unreal, this Summer GRIT is a throwback to the OG deep fakes– when mythic beasts roamed the earth, when sailors told tales of the terrors of the deep, when the sirens sang their songs, each to each.


Chose a distance goal for the month of July. This is a goal that should be challenging, that should take you out of your comfort zone, that should test your limits without breaking them.

Level up throughout the month of July by hitting mileage tiers and collecting mythical creatures from our Summer GRIT lineup.

What You Get

In exchange, you’ll get some great running swag, like an Asics summer tech tee or tank, Believe-branded headband (courtesy of Junk Headbands), and event sticker. Plus, every participant/character will be entered to win weekly shoe giveaways and incredible prize packs from Asics and Running Warehouse (sorry, no unicorn horns, we already ate them all in our run-up to the Boston Marathon).

Swag for Summer GRIT: Unreal Edition

This time around, we’re still honoring the beasts of burden who slay mountains and miles: one grand prize to the top elevation gainer for the month, and one grand prize* to the person who racks up the most mileage* for the month (proceed with caution).

You’ll also be part of an amazing community through the GRIT Facebook and Strava groups, where we support each other from start to finish.

Registration opens on Memorial Day 5/29 at 9:00 a.m. E.T. and is $45 for ONE DAY ONLY. We sold out the last GRIT in 12 hours, so don’t procrastinate on this! Learn more and sign up at the link below.

Swag option open to U.S. residents only. Free option open to everyone, regardless of geographic location.
