Endurance Race Series

🇺🇸 HAPPY LABOR DAY!

Today we’re celebrating the hard work that keeps our communities moving, including all of the runners, volunteers, race crews, and supporters who help make the ERS community what it is.

And since a long weekend is always a good excuse to put another race on the calendar, we’re taking 15% off ERS race registration! From 9/4–9/7 use code LABOR2026 at checkout. www.enduranceraceseries.com

Enjoy the long weekend, get outside for some miles, and we’ll see you on the trails!

NEW RACE TEAM MEMBER

Help us welcome Justin Nucum () to the ERS Race Team and Ambassador crew!

Justin’s trail running journey started 11 years ago while training clients for obstacle course races. What started as part of the training quickly became a love for getting outside, exploring new mountains, chasing peaks and waterfalls, and catching early morning sunrises on the trail. He also mixes trail running with CrossFit, HYROX, and other hybrid-style training.

Justin is based in Orange County and runs with the HYROX OC Run Club. His favorite local trails are around Newport Coast and Crystal Cove, and when it comes to ERS, the South Bay 24 Hour and Valencia Trail Race top his list.

We’re excited to have Justin joining the team. Give him a big ERS welcome in the comments! 👇

MEDAL MONDAY 🏅

The Dixon Lake Trail Races will be held December 12th, and this year’s race shirt and finisher medals are officially here!

Dixon Lake is not the place to come looking for flat miles. The courses take runners through the trails of Daley Ranch with a mix of singletrack, dirt service roads, plenty of climbing, and some seriously good views. If you’re taking on the 10 Miler, you’ll make the climb to Stanley Peak for 360 degree views from the top.

📅 December 12th, 2026
📍 Daley Ranch, Escondido
🏃 5k | 10k | 10 Miler

Pick your distance, get ready to climb, and earn one of these at the finish line.

🌄 ERS Friday Trailhead: Hosp Grove

Tucked right into Carlsbad, Hosp Grove is a smaller trail system that can still give you a solid workout. The trails wind through a historic eucalyptus grove (dating back to 1908), with plenty of shade, packed dirt, rolling terrain, and short climbs and descents that add up quickly when you start connecting loops.

There are about three miles of trails within the grove, but it’s easy to put together a 4–6+ mile run by repeating and connecting different sections. Along the way, you’ll also find spots with views toward Buena Vista Lagoon and the coast.

📍 Jefferson St or Monroe St trailheads
🏃‍♂️ 3 miles of trails, 4–6+ miles with added loops
⛰️ Easy

Hosp Grove is a great option for a shorter trail day, some hill repeats, or an easy run under the eucalyptus trees without having to leave the city.

Death March Running Co has our favorite runner hats… we’ll be on the lookout for an upcoming Hat collab during this years trail season. These hat will be 🔥

RUN CLUB SPOTLIGHT 🔦

San Diego has an incredible run club community, and we’re kicking off a new series highlighting the groups bringing runners together across the county.

First up is San Diego Trail Runners (). Every Monday evening, the crew meets at Mission Trails for about four miles on the trails. All runners and paces are welcome, and no one gets left behind. It’s a great group for meeting more trail runners, exploring Mission Trails, and starting the week with some miles and good company.

📍 Mission Trails Regional Park | Mondays at 6PM
🏃 Avg. 4 miles | Trails | All paces welcome
🙌 Run Leaders Daniel Smith, Walter Bueno & Deanne Ross

Check on Instagram each week for the meetup location.

The ERS community is so much bigger than the runners wearing the bibs. It’s the volunteers filling cups, working aid stations, helping at the start and finish, cheering when you need it most, and giving up part of their day to make sure everyone else has a great race. ❤️

Our runners may be the ones crossing the finish line, but it takes an entire community behind them to make race day happen. To our volunteers, supporters, crew members, and cheerleaders, thank you for showing up for our runners and for ERS. We couldn’t do this without you.
