Are the runs that are listed on this site available to everyone or only those who have access to Marine Corps Air Station Yuma? 

Both. Every run listed will include information about who is eligible to participate.

Are the runs listed on the website only MCAS Yuma runs?

At the moment yes, but we plan on expanding the website to other MCI West base runs, and runs that are within the of Yuma and close-by surrounding areas. 

Can children participate in the runs?

Each run is different, so be sure to read the information about each run, or contact the host of the run to verify any information.

Can I bring a pet or a stroller to the runs?

We can answer for MCAS Yuma. Most likely you can bring a pet to the run, but the pet must stay on a leash and you are responsible for cleaning up after your pet. Strollers are also allowed on the race course, but please use a jogging stroller, as this will benefit all involved. 

Can I get a refund for any of the races?

This includes on who is hosting the race. For the most part, MCAS Yuma cannot give refunds unless the race is cancelled- which more than likely will not happen. 

I am having trouble registering, who do I contact?

Contact Walter Sosinski at for only MCAS Yuma registration questions/concerns. 

What do I do if I am a vendor who is interested in selling products or advertising my services?

Contact our MCAS Yuma Sponsorship Coordinator at and this person will provide you with more information, or point you in the right direction. 

What if I never ran a 5K before?

Most 5K’s are fun runs, which means that walking is OK. Unless you are looking to race with others, then don’t worry about the running part. The goal is to get out there and have a good time and to follow your own pace. But if you are looking to actually run your first 5K, follow this guide by the Mayo Clinic. 

Is there anything else I should, other than work out, before race day? does a pretty good job at listing out some good things to help prepare you for a race the week of.
