Theia Friestedt   The Endurance Lab

USAC Coach and fitness instructor specializing in cycling and strength for endurance athletes. Co-owner of the Endurance Lab, providing group coaching services to cyclists and triathletes of all levels and abilities.


Theia is a licensed USAC Certified Cycling Coach, TRX Coach, and long-time yoga practitioner. Theia holds a J.D. from Faculdades Metropolitanas Unidas, Sao Paulo, and an LL.M. in American Law from Boston University. Fitness has always been a part of Theia’s life, as she managed to train consistently during her frequent business trips around the world. After a long career in Mergers & Acquisitions, Theia was finally able to pursue her passion of becoming a full-time coach. Theia combines her knowledge and experience in other disciplines to help athletes develop strength and mobility off the bike, to support their performance on the bike. Theia participates in road, gravel, and (her favorite) cyclocross races. Theia lives near Chicago with her husband, two children, and beautiful dog. She speaks English, Spanish, and Portuguese, and loves traveling and experiencing different cultures.
