* We will not be having the RUNderground in 2021 * Join us for a fun-run in the Oklahoma City Underground! The RUNderground is a fun and exciting run/walk through the underground of OKC. Explore the different colored tunnels that weave their way under the city buildings. You will see places you didn't even know existed. Have fun on this 3 loop course that will go up stairs, escalators, and weave yourself crazy. You'll wonder what direction you will be heading.
