Sharon Mexal

Sharon is in the healthcare industry and lives with her family in Orange County, CA.  She is an OC legacy runner and believes running and staying active is a big part of staying healthy, along with keeping up with routine check-ups and a healthy diet (and the occasional beer).  A melanoma survivor, Sharon is an advocate for early cancer screenings and has raised over $5,000 fundraising for melanoma non-profits as part of completing three races in the World Marathon Majors series – Berlin, New York, and Chicago.  The OC half marathon is her favorite race (there’s no place like home), with a fun expo, an amazing course, an even more amazing finish line party, and events for the entire family!   Sharon can’t wait to be an ambassador for the 2021 OC Marathon!

Courtney Brady

My name is Cheryl Vargo. I have been running for 6 years. I am part of two running clubs in Orange County, She Runs This Town (SRTT) and Team Red, White and Blue - OC. My very first marathon was the OC Marathon in 2018. This time around I will be running the half marathon. In 2020, I ran two virtual marathons and in the spring of 2021 I completed my first 50K two months before turning 50. My dad ran the very first LA and OC Marathons, and is still active today at 84. Running has helped me improve my mental health, mostly around controlling anxiety. I love the route, the race support, and the finish line celebration and looking forward to running the OC Half Marathon in November!

Ivette Cordova

Hi fellow runners! I’m Ivette from Orange County, CA. I am a very active mom and wife that loves to run/bike/hike. I also work in the Human Resources industry so, as you can imagine, it can be challenging.. going for long runs helps me keep my sane. This will be my first time running with the OC Marathon. I am ecstatic to be an ambassador and representing this event for 2021. I have a passion for running, I have since 7th grade. I was part of the Cross Country team. I ran my first 5K in Santa Ana in 2015, then my first Half Marathon in Tustin 2017. That's when I fell in love with running all over again. My biggest accomplishment was running the LA Marathon in 2019. I enjoyed every mile. I am currently training for OC Half and Run Sip Santa Barbara Hal.  Busy months ahead, so you will see me out there training hard. See you at the start line on November 7, 2021!

Desiree White

My name is Desiree or Des for short! I'm 30 years old and I have been a runner for 6 going on 7 years now. I'm a mom of a 10 and 7 year old and they love to join in on my runs and they absolutely love running in kids runs. I'm a medal collector and love running to add more medals to my collection. I have been running OC Marathon for about 6 years and complete my Beach Cities runs every year to get that special Beach Cities Medals that I love so much. I got into running during a dark time in my life and one day I strapped on a pair of running shoes and never stopped running 🙂 my goal is to spread positivity and love whether it be for fellow runners and/or outside the sport. In a world that has grown so dark and evil I believe there is still good in this world and in people and I will do my best to spread love and positivity whereever I go! I love helping others start their running careers and am ALWAYS willing to lend a helping hand and give advice to those that want it.

Erin Sremaniak

My name is Erin Sremaniak, I’m 32, and this is my first year as legacy and first year as an ambassador. I was a dancer until my 20s but was never athletic. I had done one half marathon before signing up for the beach cities challenge and had no idea what a PR was. When I achieved my first one at OC 2019, I knew I wanted to keep going and keep running. Here I am, 3 years later: healthier, faster, stronger, and 9 half marathons deep! I live in Costa Mesa and work in Newport Beach and OC is my home race- I can’t wait to see everyone at the start line!

Courtney Brady

Hello Runners! My name is Courtney Brady and I was born and raised in Orange County, California.  I am a mother to two boys (8 and 11), a wife and a lawyer.  I found my passion for running about five years ago when I challenged myself to run a 5k to see if I could accomplish it.  Since then I've run seven ultramarathons, two marathons, and lots of half marathons and 5ks! I love running for the time it gives me to process the stress of a busy working mom life and the movement I need to feel recharged. The OC Half Marathon is my absolute favorite road race because of the awesome course and people.  When I'm not training for that,  you can find me in our local mountains and trails or reading (or, more realistically, living that mom life) Happy Running!

Jenny Bradley

Hi, I'm Jenny, I'm originally from the SF Bay Area, and I've been running for about four years now! I picked it up very casually, until my sister shared an interest in running a half marathon together. Since then I've covered the distance of one 50k, 10 marathons and 21 half marathons, plus countless training miles! The running community has kept me running strong -- first in LA and now in beautiful OC! I am always down for a run club night, and let's face it, at 38 years old and always training for something, they are my only chance at a thriving social life! As a resident of the OC for just over a year, I'm so excited to represent all this race encompasses, from the energy of the runners and community, the gorgeous course, the Beach Cities Challenge and beachside training miles!

I love the OC Marathon and I am ecstatic to be representing this event for 2021. I’ll be racing the Half Marathon in May and I’m shooting for a sub 1:40. Long-term running goals include capturing that unicorn (looking for my first BQ!) and running a sub 21 min 5k. I love to run and have been injured enough to know that nothing is guaranteed. I never take a run for granted and I always run with a love for the sport.

We'll be doing some training for the OC Marathon, so come check us out. This will be my 3rd time running an OC Marathon race. This is such a great course, and I recommend it to my runners. I will be participating in an event called Run Across Haiti in May, where I'll be running 200+ miles in 8 days across the country of Haiti to show that it is not a place to be feared, and to help end poverty by providing dignified jobs to families out there.

Naader Reda

I've been a high school history teacher for 13 years and going strong. I was excused from PE in school due to foot problems, but perseverance and time in the gym helped me see that I could really do physical activities. I ran my first marathon in November 2016 and never looked back! Because I graduated from Buena Park High School, it's especially significant that I'm able to represent the communities that I called home when I was growing up. In my spare time, I enjoy participating in food challenges, reading about history, and making YouTube videos.

Victor Hurtado

My name is Victor Hurtado from Santa Maria, CA. I started running 6 years ago in order to lose a few pounds and be a bit more healthy. Little did I know I would lose 80 pounds and still be running. Went from having a goal of running a 1:30 half to running a 1:14 and also a goal of breaking 3 hrs for the marathon to running a 2:47. I love to run and be active. You can find me running the streets of Santa Maria on a daily basis. Follow me on Instagram as I try and reach some new goals in 2021at the OC Marathon.

Hi, my name is Nani Luculescu & I live in Los Alamitos. I love racing a variety of distances & am continuously pushing myself to hit bigger goals every year.  I’m currently heavy into training for my first full Ironman race next March and will toe the line in beautiful New Zealand. For me, running the 2018 New York Marathon was extra special because I raced and raised over $5000 for Global Lyme Alliance in memory of my dad who died of Lyme induced ALS, 7 years ago. I began running as a way for me to deal with the grief of losing him and now I race to honor him.

Becca Brockmeyer

Caitlin Oishi

My name is Caitlin Oishi and I’m stoked to be repping the OC Marathon this year! I began running in high school on my track team, but it fell to the wayside over the years until I decided I wanted to get into better shape for my 30th birthday, when I ran my first Disneyland Half Marathon. From there I was hooked.  I live in Marina Del Rey and love doing my training runs along the beach path. During the week I work in reality television and on the weekends, chances are you’ll probably find me at Disneyland. When not running or working, I enjoy spending time with my favorite running partners, my husband Derek and dog Finn (ok, he’s mostly a cool down walker).

Megan Huston

Megan grew up playing soccer through high school, but didn’t start running seriously until after a cross-country move to Texas and later, Georgia. Leaving family and friends, she made the bold move to move her life to a different state to explore greater opportunities. After two soccer-related knee surgeries, running provided her both a way to explore her new home and stress relief. The stress relief grew into a passion and love for the sport. Megan has now completed nearly 90 half marathons and 8 full marathons with PRs of 1:50 and 4:19, respectively. Megan aims to encourage others to pursue their passions however scary they may be. She paces races a lot around Southern California, and enjoys encouraging and motivating others to push their own limits, whether for a PR or first-time half marathoner. OC is one of her favorite So Cal races and she hopes to see you out there in May!

Justin Dugat

My running journey started with meeting my wife who is a lifelong lover of running. I completed my first half marathon 9 years ago and was hooked. Running is a great mental and physical challenge, not like any other with an emphasis on the mental. I have always been fit and athletic but running and training for marathons takes it to a whole other level. I enjoy so much the end result when you finally complete the race that you’ve been training for months for, it’s a total rush! The OC marathon in particular is what brought my wife and I to move to Newport Beach. We’ve ran it for 5 years now. We fell in love with the race and Orange County, so much that we plan to continue to run this race for years to come!

Celerina Dugat

My love for running has been strong since I was a young girl. I couldn’t wait for track day in grade school P.E. class. I continued running all through my teen years and into my adulthood for exercise and simply for the love of running. All throughout my life during good times and bad, I have turned to running as a form of therapy and a treat to myself. In 2010, as a self challenge, I ran my first 1/2 marathon and never looked back. In 2015 my husband and I traveled from our home state of Texas to run our first OC 1/2 Marathon and fell in love with the OC so much we came back for “Runcations” to run the race for the next 4 years. One of my running goals has always been to be a race ambassador and I’m so honored to be chosen for the 2021 Ambassador team. I can’t wait to see you on race day as I cross my 26th finish line! Have a fabulous day and remember to always be... Running on Rosé. Cheers!

Elizabeth Forney

Hi! My name is Liz! I’m a 28 year old marathoner. I’ve always grown up loving to run, but only in the last few years did I catch the marathon bug. The OC Marathon was the third marathon I ever did, and I’m hooked. I already love Newport more than anyplace in the world, so running a marathon there made it a thousand times better! When I’m not running (which is rare) I’m hanging with my husband and golden retriever! We love to stay active and take walks and hikes!

Currently, I’m out recovering from an unfortunate injury that has sidelined me for a bit, but I’m planning on coming back to the running game stronger than ever! And I’ll absolutely be there to volunteer and cheer everyone on at the race this year!!!

Moises Alvarez

Moises first took notice of the running scene in 2009, when his younger sibling trained for the LA marathon. Moises was fascinated by the idea of running such distance. With an overweight and sedentary lifestyle, the thought of running a marathon seemed out of reach. It wasn’t till 2013, when Moises began to run and within months signed up for his first half marathon. Over the years Moises has participated in several marathons. His discovery of trail running gave him a new passion for running ultra’s. Now you can find him running mountainside trails on any given time. He always remembers how difficult it is to start running and train for any distance, even if it’s just recreational. He enjoys the satisfaction of helping out others train and reach their running goals.
