I have completed the Cowtown Challenge 10K/Half in 2017, 2018 and 2019. I complete the challenge because why not, I was already going to be down might as well run more and get more swag. I enjoyed coming back to this race several years in a row. It was mainly because of the price but also there was a series so if you completed 2017-2019 all the medals would fit together. I would highly recommend this race, from the expo to race it is one you can't miss. I really like having the challenge and I know that in 2020 it changed slightly as there is an additional fee for a better challenge swag. I also like having a participant shirt along with a finisher shirt. If you sign up at the expo for the next year it is cheaper. The expo is one of the best one I have seen with lots of vendors and free stuff. Definitely check out this race.
