Endurance Race Series

We’re excited to welcome Strive Soda to the ERS family as our newest sponsor!

Strive is a hydration soda made for people who like to move. Each can combines bold soda flavor with electrolytes and organic wildflower honey, giving you something cold and refreshing to look forward to after the miles are done.

You’ll get a chance to try Strive at ERS events this season, so make sure you grab a can, kick back with your trail friends, and let us know which flavor is your favorite. We have a feeling these are going to hit pretty well after a few hours on the trails. 😎🥤

Welcome to the family, Strive Soda! We’re stoked to have you along for the season.

COMMUNITY SPOTLIGHT 🔦

After taking four years away from running, Danielle () found her way back in May 2025 and discovered a love for the trails along the way. Being outside in nature drew her in, but seeing complete strangers support and encourage each other is one of the things that keeps her coming back.

Her favorite ERS race is the Black Mountain Half Marathon. She loves the challenge of taking it on each time and the feeling of finally crossing that finish line after everything the course throws at her.

Her advice for anyone thinking about signing up for an ERS race is simple. ""It’s worth the challenge and the feeling you get when you push yourself.""

We’re glad you found your way back to running and into the ERS family, Danielle! 👏

The Jester would like to remind you that there is money on the line at South Bay 24 Hour. 💰🤡

The first runner to hit 125 miles during the 24 hour race will take home a $1,500 prize purse provided by Death March Running Co! That’s 125 miles of running, walking, snacking, questioning your decisions, finding a second wind, losing it again, and somehow continuing to move forward.

Think you’ve got 125 miles in you?

📅 July 24 and 25, 2026
🏃 South Bay 24 Hour
💰 $1,500 to the first runner to reach 125 miles

The clock is ticking. Who’s going for it?
