Sometimes runners like to dress up on race day. I've been participating in Disney races since 2016, and it's always a lot of fun to dress up for those events. Twice I've had a blast dressing up as Star Trek characters during Star Wars races: once as a Discovery Medical Officer and once as a TOS-Era Starfleet Command Officer.
I was always looking for my next Star Trek costume for running, so I was heartbroken to learn Disney won't host Star Wars races going forward. That won't stop me from themed race costumes, though. Here are some more ideas for easy Star Trek themed running outfits.
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.

Perfect Race Accessory: Star Trek Running Hat
Add a Star Trek running hat to your outfit for comfort and extra theming. I have this hat in yellow and it was perfect to wear for a race. It's made of moisture-wicking material, has an adjustable strap for a good fit, and comes in three Starfleet colors. Keep the sun out of your eyes or rain off your face when you wear a billed baseball-style running hat like this officially licensed cap in three colors.
