TrailFit is starting up for the 2026-27 season. On Saturday, most of our trail crew leaders for a feast and planning session: Greg Bergeron, Zhen Low and his son Lukas, Doug Gillingham, Jose Llanos, Tom Cross, Jon Good, Evan Goodwin and John Vanderpot. Also at the meeting was the SURF Prez, Caryn Sandoval. Anita and Ken had carefully set up for dining al fresco on the patio but then just as everyone arrived the thunder and lightning started followed by heavy rain. Great Mex from Kaelin’s Market in El Cajon. Excellent strategy meeting and fun to catch up with everyone’s activites over the summer.

We’ve got a few dates on the calendar and will be adding more in the next week or two. We are grateful for all our hard working volunteers who are willing to drive up to our local mountains and help keep our trails in tip top condition. Please join us. We start early and wrap up by late morning followed by a nice lunch together. Excellent ultra running race intel and trash talk!

Did we all celebrate the final days of summer last weekend with Cuyamaca 100k? Feels like it! 🌧️ Congrats to all SURF members who ran, volunteered at the aid stations, swept the course, and to Mariela on her first year directing this classic race. The energy was great, temps weren’t *too* spicy, and we had fun showing up.

Big congrats to Katita Kazcpu who completed her UltraSlam with the final distance! 62 miles and change is no small feat, even with a 100-miler out of the way.

MAMMOTH TRAILFEST WEEKEND 🦣 This race series features five race distances ranging from 1k to VK to 50k. Unsurprisingly, many of the SURF’ers in attendance went with big dreams but every distance is unique and SUPER scenic. Shout out to those who ran the triple!

This event is fun for racers, volunteers, and friends + family. With gorgeous views and trails to enjoy, abundant camping and lodging, and easy shuttles (plus gondola rides), it’s a weekend worth attending for the first or fifth time.

San Diego representation was strong in the Sierra last weekend. Who’s counting down the days until next year? 🙋‍♀️🥹

What an incredible turnout for LOOP 3 of the Cuyamaca 100k route! 🔥 These training runs are an amazing way to preview the course with friends and refreshments along the way. Whether you’re toeing the start line or prefer to do a long run with company, it was great to see everyone on the trails and at the post-run SURF picnic yesterday! 🥪

This loop is surprisingly runnable with that sneaky climb at the end. Good incentive to save your legs on race day.

💥 SURF is not your average run club but instead a non-profit who maintains the trails we race on, provides aid station volunteers and provisions at local events, hosts several annual parties/races, and sponsors training run picnics. Your membership supports our ability to keep up traditions and support our local ultrarunning community. Learn more on our website and join us if you haven’t already!

See you at Noble Canyon this Saturday!!! 👋

Did you forget to join SURF at the Noble Canyon training run? I know — those last 3 (or 5) miles got us good. 🥵 If you appreciated the shade, sandwiches, and support at the finish line + 45 friends to share miles with, consider signing up today to contribute.

You small annual fee goes towards:
👉 post-run picnics at the trailheads
