About Us

The Cox Running Club was formed in 2012 to promote running activities in the DFW area. Membership is open to anyone interested in running, walking and fitness.

The goals of the club are to provide:

Social events
Quality local races
Companions for exercise or racing
Information and advice related to running, walking and fitness

Behind The Club

Volunteers Who Put It Together:

In 2012, we noticed that Fort Worth and surrounding areas were in need of a local running club that was for every runner.  What does every runner mean?   No matter your pace or where you place, if you run, you are a runner.  Regardless if you are a man, woman, child, old, young, fast or slow, if you get out there, you are a runner!

We are a group of volunteers who truly enjoy giving back to the running community and we want to help you achieve your running goals. We will provide a fun and safe avenue for fellowship, workouts, running and racing. We want you to help you make friends, running friends, and hopefully make you a better runner! Cox Running Club: “Changing lives one mile at a time.”


Demery Cox

demery Demery:  I was practically raised in the running community and feel it has been a part  of my  entire life. Due to my parents influence, running is a way of life or me. My father,  Ricky Cox is  a very accomplished runner and when my mother was younger, she used  to run. Running  and training to compete has shaped my life and character as a whole.  Since I co-own Cox  Racing Services with my dad, Ricky, running is also a large part of  my professional life. I have  4 young boys, Avery, Demery Jr., Brian and Ashton.

I am very family orientated man and try to include children in all the races that I direct,  co-direct and take part of. I would eventually like to be able to go to schools and talk to  children and young adults about the benefits of running and a healthy lifestyle. I have  met a lot of great friends through running, some of which I now consider family. Since the running community has been so good to me and such a large part of my life, I try to show my appreciation and give back to the community every chance I get. Running is a honest sport, you get what you put into it.



My name is Ricky Cox. I have been married to my beautiful wife Debra Cox of 35 years and I have 2 sons, 1 daughter, and 12 grad kids. My grandkids keep me busy.  I am currently a supervisor at The-T (Fort Worth Transit). I have been working here for over twenty years.  I am also Co-Owner of Cox Racing Services, a local production and timing company. The community has been amazing to me! I cannot stress how big of an impact running has had in my life. I have been running since my junior year in high school (O.D. Wyatt High School).

I decided to take running serious a couple of years after I graduated from high school. Since then I have ran and competed in over 1,000 local and national races. I won the Cowtown Marathon 3 times and qualified for the Olympic Trials in 1988. My PR in the Marathon is 2:17:26 (Boston), Half Marathon – 1:06:41, 10K- 29:48, 5K – 14:39 and Mile – 4:11. I still enjoy running and staying fit. I still participate in a few local races to go out and have a great time. I understand I am over 50 years old so I know my days of blistering fast running and PR’s are behind me. But I still enjoy training with my son and averaging 30-40 mile a week.



Johnny & Elizabeth MendiolaJohnny & Elizabeth Mendiola

Elizabeth:  I started running in my adult life after I became a stay at home, home schooling, work from home wife and mother. I enjoy running distance races and training for longer distances. I have 4 children and am happily married. I have an extensive volunteering background in the running community. I volunteer at races, large and small and served on another local running club board for over 7 years. I really look forward to this new opportunity and can’t wait to make more running friends and run with YOU! You can contact me at runfar@att.net

Johnny: I was introduced to the running lifestyle by my wife, Elizabeth.  It took about two years of watching her grow as a runner before I decided to join her at the age of 30. I started because I also wanted to get in shape and spend more time with her. I ran my first 5K at Cowtown in about 35 minutes, and that was my first taste of the adrenaline at a start line, and it was addictive. I continued to race and meet many runners and realized that a large running community existed that is full of great people who want to encourage, coach, talk and run with each other. My favorite distance is the 5K because I like to feel like I’m running fast, to which I have learned is a relative term.  I probably won’t win any races, but every now and then, I place in my age group which is exciting and keeps me motivated. My PR for the 5K is 22:05, (but I hope to shave off 6 seconds someday), 10K PR is 53:34 and ½ Marathon PR is 1:51:26. I enjoy one or two half marathons a year, but longer distances do not really appeal to me. I do enjoy long runs (10-12 miles) with my wife; it’s a fun, healthy way to spend some time together without our 4 kids interrupting!

We used to push our daughter in a jogging stroller and now she runs 5K’s. I enjoy racing with her and seeing her grow and fine tune her running skills. Our boys now run 1K’s and I am looking forward to watching them as they take up this fun sport. Running has been fun because of the great people I have met and the time I spend with my wife and kids. I hope to make new running friends and see existing friends at club events and continue to have good times. You can reach me at johnnymendiola@gmail.com


Tomas & Bernadette RazoTomas & Bernadette Razo

Tomas Hello, My name is Tomas Razo. I am married to Bernadette and we have three beautiful daughters who are also runners Adalia, Brooklyn and Irelyn. I was born in Pharr, Texas, but was raised in Fort Worth from the age of six. I started running at the age of 10, after asking my neighbor for training advice, who happened to be Ricky Cox. Ricky trained me and took me under his wing throughout my middle school and high school years, while I ran track and cross country. I decided to try something different after high school and became involved with powerlifting and bodybuilding. At the age of 28 I decided to return to my love of running.

Once again going to Ricky for advice and I haven’t looked back. I still weight train along with running ,cycling and swimming and will compete in triathlon occasionally.

Bernadette:  After supporting my husband’s running for years, I asked myself one day if running was for me. I quickly began my running routine and couldn’t get enough. Eight years and many races later, I try to run as much as I can. While being happily married and a busy mother of three girls, finding the time to run is not always easy. But thankfully running is something our entire family loves to do.

My oldest daughter has special needs and is involved with Special Olympics and my two youngest girls are twins and do all their races together. I’m excited to become more involved with the running community and look forward to serving on the board of Cox Running Club. Please contact me with any questions at bernadetterazo@gmail.com
