🌄 ERS Friday Trailhead: East Fortuna Trails

Looking to explore a different side of Mission Trails? The East Fortuna trail system inside Mission Trails Regional Park delivers runnable fire roads, rocky singletrack, steep climbs, and incredible ridgeline views. Expect a little bit of everything out here. Smooth dirt sections where you can open it up, punchy climbs that will get your heart rate up fast, and technical rocky stretches that keep you paying attention.

📍 East Fortuna Staging Area (Mission Gorge Rd)
🏃‍♂️ 3–12+ mile route options
⛰️ Moderate to Difficult

The East Fortuna summit rewards you with panoramic views of the surrounding mountains, downtown San Diego on clear days, and some seriously good sunrise and sunset miles. It's the perfect spot for off-season vert, long miles, or exploring new terrain.

Big thank you to Gnarly Nutrition for supporting the Endurance Race Series this season. Gnarly makes products that runners actually use and trust, from hydration and fuel during long efforts to protein and recovery mixes that help keep the body moving day after day.

We’re especially big fans of how easy their drink mixes are on the stomach during tough efforts, because nobody wants to play roulette with their nutrition halfway through a race.

Stoked to have Gnarly as part of the ERS family this year. Be sure to check them out at our events and show them some love.

The Endless Summer Trifecta is here! ☀️

This summer, we’re connecting three of our favorite events into one big challenge and one seriously cool medal set. Complete Trails n' Vines, Mission Trails Twilight Runs, and South Bay 24 Hour (shorter distances ok), and your three medals will fit together like puzzle pieces to create the Endless Summer Trifecta medal.

From wine country trails and golden hour singletrack to overnight miles, each race brings a completely different experience and atmosphere. Put them all together and it becomes the ultimate ERS summer.

We wanted this challenge to feel like more than just collecting medals. It’s about showing up all summer long, chasing adventure with friends, staying consistent through the heat, and making memories out on the trails.

Who’s going for all three? 🔥🧩

Still day dreaming of our first ever wine run!

🎉 Happy Birthday to ERS Ambassador, ON Running Race Team member, and Ultrabuds Run Club leader Patrick ()!

Patrick is the kind of person who makes every group run better. Always encouraging others, always showing up for the community, and somehow still smiling after absolutely cooking everyone on the climbs. As an ERS Ambassador, Patrick goes above and beyond to support the community by leading group runs, helping welcome new runners into the sport, representing ERS out on the trails, and bringing positive energy to every event he’s part of. He truly embodies what this community is all about.

We’re lucky to have you in the ERS Family, “Fast Pat.” Hope your birthday includes good trails, good friends, and at least one run where you let the rest of us keep up. Show Patrick some birthday love in the comments. 👇

This is what our trail family looks like. Real smiles, tired legs, and that feeling you only get after sharing miles with good people out on the trail. It’s more than just the run, it’s the laughs, the encouragement, and the moments that stick with you long after the finish line.

Every ERS event brings together people who show up for the run and stay for the community, and it shows in moments like this.

Come see for yourself why so many runners keep coming back.

💗Happy Mother’s Day from the ERS Family.

Today we’re celebrating the moms who show up in every way. The ones pushing strollers, chasing finish lines, cheering at the tape, and somehow still finding time to get their miles in. These are the women who balance it all and still make it out to the trails. Early mornings, long days, tired legs, and big smiles.

To all the ERS moms out there, we see you and we appreciate you. Thank you for bringing your strength, your energy, and your heart to every start line. Drop a 💗 and tag a mom who inspires you.
