This was yesterday's prompt, but I didn't have the time until now, here you go!

"Yo!
Stoked that you're creating the Austin Run logo! We're a large running event that happens once a year in Austin, Texas. We had over 5,000 participants last year and now it's time to get some great branding materials.
Austin Run is a charitable event for autism research and raises money for families in need of care, education, and information. The event is so much fun and many people dress up in crazy outfits. Last year we had someone dressed as Darth Vader followed by 50 Storm Troopers!
Anyway, the logo style is really up to you and we'd love to see what you can come up with. It could feature the Texas state shape, a landmark that represents Austin, something that represents running, or even just a text logo! Feel free to something whacky and fun or something more simple. I'm sure we'll love whatever you do!
Stay awesome,
Justin Reed
Austin Run - Charity Run for Autism"

I really liked the idea of people dressing up for the event, so here you have a letter R running with a cape on, I had fun with the idea.
