This polyester dress would be a great start to a running outfit. You might want to wear black tights or shorts underneath to prevent chafing or have pockets to carry race needs. This dress is made of polyester but doesn't look to be moisture-wicking, so consider wearing this for shorter distance races.

In The Next Generation, blue Starfleet uniforms were for medical and science officers. This Star Trek rash guard is made of thick, moisture-wicking material. It's made for swimming, so it's meant to have a snug fit. I actually have this top and have used it for kayaking. It would be an easy starting piece for a complete running outfit. Add black bottoms (running skirt, pants, or shorts), and you'll be good to go!

Dress up as Mariner, Boimler, or another command-track ensign with this funny cartoon-style Star Trek uniform costume t-shirt. This is a lightweight top made of polyester. Though it's not a technical, moisture-wicking weave, it's light and comfortable to wear. Again, just adding your own black pants or skirt will complete this look. You could dye your hair purple if you're going as Boimler, or add a fun alien prosthetic to your face or body to add some more authenticity to your running costume.

I wore this officially licensed long sleeve Star Trek costume shirt for the race. The command officer shirt is made of polyester, but it's not very lightweight or moisture-wicking. It was great for a 5K, especially this one, since it was a cool and rainy morning. I might wear this for a slow 10K too, but for a longer distance, or for actual racing, it might spell disaster in the form of chafing or over-heating.

For my race, I wore a black SparkleSkirt that I had in my closet already. Any black bottoms would work well with this costume, like this affordable black running skirt with shorts attached.

If you end up liking this particular skirt, it comes in different colors and cuts so you could get more to have on hand for future costume runs.

This awesome Star Trek running hat is made of moisture-wicking tech material and comes in all three familiar Star Trek uniform colors (blue and red in addition to yellow). I got the yellow one and it's a great match for the shirt. I like to run in a hat anyway so this was a great find.

This sublimated costume t-shirt was perfect for my needs. The Discovery uniform shirt comes in several different colors, including designs for command officers, science officers, and engineering officers (all blue with different detailing).

This is a polyester shirt with sublimation all-over printing so it looks great, but it's not very lightweight and it's not moisture-wicking. It was a relatively cool (for Florida, in April) morning for the race, so I opted to wear a white long sleeve tech shirt under this costume shirt. That gave me the look of wearing a long sleeve uniform top. This way I was also able to keep warm while standing around waiting for the start of the race, and cool once it was time to start running.

I really like Headsweats visors, so I did a little crafting to make a plain white Headsweats visor into a costume hat for this outfit. I used dark blue felt letters to spell out DISCO, for Discovery, on the front of the visor.
