This is a chip-timed race. There are also 4-member relay team registrations available for the 8-hour ultra, with options to run, walk, or ruck, and one person on each team participates at a time. Cash prizes will be awarded to winners. The 0.8-mile paved loop circles the beautiful Granny White Park and includes a few gentle hills, with temperatures in early November typically ranging from the 30s to the 60s. This event was created to honor Lieutenant Colonel Shelli Huether, who, along with Captain Jessica Wright and Senior Master Sergeant Scott Bumpus, tragically died in a plane crash in McMinnville, TN, on September 8, 2020. Shelli had a servant’s heart, volunteering countless hours with the USO, Operation Stand Down, and many other charities and organizations, and she was also an avid runner who constantly set new goals for herself. This race and fundraiser aim to honor Shelli and all veterans while raising money for incredible charities in her name. www.shellihuetherhonorrun.com

Memphis, Tennessee (United States of America) - "Running From Yeti - Memphis". In Nepal's folklore, Yeti is an "abominable snowman" who looks like an ape, is taller than an average human, and is believed to live in the Himalayas, Siberia, Central and East Asia. Yeti, during the pre-19th century, was believed to be a "glacier being" who was worshipped by the indigenous communities. However, in Memphis, he is a cute big fellar that we can't wait to see this January 10th, 2026—to playfully run from him, take pictures with him, high-five him, and have a chilly party with him! Come join us and run, walk, jog, or cartwheel; earn your comfy hoodie for all participants; choose between one of the bonus swag; enjoy tasty treats and food; wear white to match Freddie; and dance to some Yeti music. www.runsignup.com/Race/TN/Memphis/RunningFromYetiMemphisTN?aflt_token=Nktw0AUB3nF4FPeh7Y7AWqQewFdw9sGt
