On the Appalachian Trail Tara is known as Candy Mama. She received that name during her nearly 6 month thru hike of the 2,200 mile trail in 2019. That experience inspired her to live life to the absolute fullest and she made a vow to spend as much time on trails as possible. As a wife of a U.S. Navy Diver Tara moves around the country often. She began exploring ultras in California in 2021 and ran her first 100 miler that October in North Carolina. After that first 100 mile race it became her new obsession. Since 2021 she has run 17 ultras and podiumed in all but 3. Tara has set Fastest Known Time speed records on the Mountains-To-Sea Trail (1,175 miles), Benton MacKaye Trail (289 miles), and the Colorado Trail (486 miles). She enjoys spending long days and nights on trail and hopes to be doing that for the rest of her life. If you see Tara during a race say hi! She loves to chat. Her favorite quote is “everywhere is within walking distance if you have the time.” by Steven Wright.

Mike McKnight has been running ultras for just over a decade. His intro to ultras was very unique. In 2012 he broke his back in a skiing accident. His injury caused him to lose his job and defer his college classes for a full year. He miraculously recovered within a few weeks, and because he didn’t have a job or classes to attend, he started running a lot of miles every day. This put him on a path to ultra running, and hasn’t looked back. Mike has an amazing wife and two kids, and resides in the mountains of Northern Utah. He loves pushing his limits and believes that comfort is a waste of potential.
