Sombrero Ultra Running Festival ( SURF )

The Why

We wanted to create a premier event that would bring runners from all over together to enjoy miles in NE Florida. It was pivotal to that we allowed ample time for runners to reach their goals whether it is their first ultra, first 100-mile buckle or push themselves for more miles than they have ever done before. Join us in Middleburg, FL (just outside of Jax) at the Clay County Regional Sports Complex for the 2nd Annual SURF for a weekend full of fun with running, vendors, and other shenanigans. This is sure to be a fun and inspiring weekend. We will have some neat Valentines giveaways as well and some sort of Presidents Day Theme as well! Our Inaugural event was a smash and the participants really enjoyed the course and the ALL NIGHT/DAY FOOD AVAILABLE!

Pacers

The only runners that are allowed to have pacers are runners doing the 24 and 48 hour events. Pacers are only allowed after the runner has completed 12 hours and they must register with the RD or staff. We will allow exceptions on a case-by-case basis if there is a special need. Only Mike Martinez or Russell Hartzell can authorize the exception.

Crewing

There will be a runner's village for canopies, tents, and crews. Runners will have the option to crew out of their vehicle if they prefer. You can bring an RV but there are no RV hookups and there will be an RV fee of $15 to be paid at the race site in cash, Venmo or PayPal.

RV Parking

If you plan to bring an RV to the event please fill out this form and let us know. We want to make sure we allocate enough spots and space. You can pay through UltraSignUp as an add-on (there will be an extra UltraSignUp fee) or cash on site. We also take Venmo and PayPal. The QR codes for Venmo and Paypal are available in the RV Form.

Sanitation Protocols

Unfortunately, we're still living in the era with covid and other diseases, so we need to be safe to protect our runners and our volunteer staff. At each aid station we will have volunteers available to ensure that all hydration igloos will be sanitized adequately.

Aid Stations

Aid Stations There will be an aid station at the start/finish area which you will pass by 2x on each loop with the standard Ultra fare and we will have Skratch electrolytes and a stockade of pickle juice. Since this is a shorter loop and a cooler time of the year we will only have one aid station. This is a cupless race. All runners will need to bring their own bottles, hydration vest with bladder or collapsible cup to the event. Some of the Aid Station Items will be: Water Skratch Coke Ginger Ale Bananas Oranges Candy Bacon Chorizo and egg burritos Quesadillas Potatoes Broth ramen noodles burgers hot dogs brats. We will also have the Hot Food grilling area at the 1/2 way area in front of the bathrooms like this year! We have a personal chef John Ramirez that left EVERYONE well fed, please be courteous though and recognize he is not a " short order cook". We will have regular cooking schedules where we will cook breakfast items in the morning and lunch items ( beginning at 11am)

Music

John Ramirez of Fat Daddy J's will provide the tunes for the event or the soundtrack to your misery depending on your perspective.
