Lyle was born and raised on a small cattle ranch in Whidbey Island, Wash. Growing up, she was active in the local Pony Club and competed in eventing before focusing solely on dressage. She was a member of medal-winning teams at the 2002 North American Junior Dressage Team Championships and the 2004 North American Young Rider Championships.
During the summer of 2005, Lyle began working with Debbie McDonald as a working student, and has since become assistant trainer for the Thomas family at River Grove Farm.
Lyle and Wizard have been forming a solid partnership over recent years. Wizard was imported from Holland as a five-year-old by the Thomas family; McDonald rode Wizard originally, before Lyle took over the ride in 2006. The pair competed at the Intermediaire I level their first year together, and by 2008 they clinched the USEF Young Adult “Brentina Cup” Dressage Championship. In their first National Grand Prix Championship at the 2009 Collecting Gaits/USEF Dressage Festival of Champions, Lyle and Wizard made a statement by winning the Freestyle.
In February of 2010, Lyle swept the Grand Prix and Grand Prix Special with Felix and the Grand Prix Freestyle with Wizard at the CDI3* in Thermal.
Lyle spent the early part of the summer of 2010 training and competing with Wizard in Germany. The pair finished in the top 15 at the CDI Hagen, and continued to gain experience at the CDI Munchen Reim. While in Germany, Lyle spent two weeks training with legendary dressage rider and coach Klaus Balkenhol.
Lyle and Wizard had a successful year in 2011. At the Great American Insurance Group/USDF Region 8 Dressage Championships, the pair won the Grand Prix Freestyle and finished third in the Grand Prix Test. Lyle and Wizard finished out the year by winning both the Grand Prix Test and the Grand Prix Freestyle at Dressage at Devon.
Lyle spent the first half of 2012 cruising to strong results on the East Coast. At the World Dressage Masters Palm Beach CDI4* presented by International Polo Club Palm Beach, Lyle and Wizard won the Grand Prix Special and finished fourth in the Grand Prix Freestyle. The pair took top honors at the 5* West Palm Beach in both the Grand Prix Test and the Grand Prix Freestyle.

Later that summer, they traveled to the United Kingdom to participate in the 2012 London Olympic Games to compete as Individuals.
Following their Olympic appearance, Lyle and Wizard had a light year in 2013, but still finished second in the Grand Prix Freestyle and third in the Grand Prix Test at the Gold Coast Opener CDI-W.
Lyle and Wizard were back with a vengeance in 2014, beginning the year at the Adequan Global Dressage Festival (AGDF). During week one, the pair won the Grand Prix Test. Lyle rode Wizard to a first-place finish in the Grand Prix Special CDI4*, as well as earning second in the Grand Prix Test CDI4* during the AGDF week five. Two weeks later, the pair helped USA Team I claim top honors in the Wellington Nations Cup CDIO3* sponsored by Stillpoint Farm. Lyle also received the Individual Gold medal for her Grand Prix Freestyle with Wizard. Next up, she and Wizard won the Grand Prix Freestyle and were second in the Grand Prix Test in the Palm Beach Dressage Derby CDI-W. The pair competed in the final week of the ADGF, taking home the wins in the Grand Prix Test and the Grand Prix Special in the CDI5*.
Lyle traveled to the U.S. Dressage Festival of Champions presented by The Dutta Corp with Wizard and had a strong showing. The pair was third in the Grand Prix Freestyle and fourth in the Grand Prix Test and Grand Prix Special, to finish fourth overall in The Dutta Corp/USEF Grand Prix Dressage National Championship. For their efforts, they were named to the Short List for the 2014 Alltech FEI World Equestrian Games U.S. Dressage Team. The pair then headed to Europe for the summer to hone their skills. At CDI4* Fritzens-Schindlhof, Lyle and Wizard were third in the Grand Prix Freestyle and fifth in the Grand Prix Test. They tied for 10th at CDIO5* Aachen in the Grand Prix Freestyle before finishing fourth in the Grand Prix Test and Grand Prix Special at CDI3* Verden.
