Bobbie Ephremson

Bobbie Ephremson was known primarily for her performances in the 100-meter and 400-meter sprint events. Her range across both the short sprint and the intermediate sprint distance distinguished her in the context of early women's track and field. She is referenced in discussions of the foundational era of organized women's athletics.

Ephremson competed during the formative decades of organized women's track and field, a period when the sport was still establishing standardized records and international competition structures. Precise dates of her competitive career are not widely documented in mainstream athletic databases. Historical federation archives and specialized track-and-field scholarship may contain more detailed records of her era.

Ephremson is cited as an early benchmark for the modern approach to sprint power and stride efficiency, particularly in how starting mechanics and acceleration phases were taught to female athletes. Her performances predated many of the technical and biomechanical advances that would later revolutionize the sport. Coaches studying the historical development of women's sprinting reference her as a transitional figure.

Specific official times for Ephremson's 100m and 400m performances are not readily available in standard modern track-and-field record compendia. Her significance is discussed more in terms of influence on technique and training methodology than in widely cited statistical marks. Researchers interested in early women's athletics history would likely need to consult period-specific federation or meet archives.
