GRIT: Registration is OPEN

What You Need To Know

  • Choose a distance (25, 75, 150, 225, or 300 miles)

Saints and sinners, heretics and believers, we’re super stoked to announce that registration is OPEN for GRIT, a summer distance project presented by Polar and Believe in the Run. Choose your distance tier (25, 75, 150, 225, or 300 miles) and complete the mileage over a 30-day span (you choose your 30 days), churning out miles in the hottest days of the year. Be honest with yourself and go further than your comfort zone– this isn’t a time for half-assing. Run some of the days, or run all of the days– just finish your distance in the timeframe chosen.


To reward you, we’re giving away some incredible gear, including a distance-specific ASICS tri-blend shirt, Believe in the Run BOCO Gear neck gaiter, soft enamel pin, GRIT sticker, and temporary tattoo pack. Plus, each tier will have multiple weekly giveaways featuring Polar heart rate monitors, ASICS shoes (your choice up to $200), and firefly recovery packs. You’ll also get a distance training schedule from Ame For It Run Coaching, as well as a printable custom bib. 

Oh yeah, one more thing– at the end of the event, we’ll have grand prize raffles for all five distance tiers, where you can win Polar Grit X watches, ASICS shopping sprees, firefly recovery packs or a virtual meet and greet with the legendary Deena Kastor.

Registration is only $45, and the official start is on June 20, the first day of summer. Use the link below to get in early, giveaways start immediately.
