This article covers everything you need to know about Grete Griffin: her background, her athletic career, how she and RG3 met, their wedding, their growing family, and where you can follow her online. If you’ve been curious about the woman often seen cheering RG3 on from the sidelines, here’s the complete story.
Who Is Grete Griffin?
Grete Griffin was born Grete Šadeiko on May 29, 1993, in Türi, Estonia. She grew up in a family with a strong athletic background — her older sister, Grit Šadeiko, is also a professional heptathlete who represented Estonia internationally. Track and field runs deep in the family, and Grete followed that same path from a young age.
Standing 5 feet 10 inches tall, Grete built her athletic foundation in Estonia before moving to the United States to continue both her education and her sporting career. In the fall of 2012, she enrolled at Florida State University, where she competed for the Seminoles’ track and field team while pursuing her studies. Florida State gave her the platform to compete at a higher level and eventually cross paths with the man who would become her husband.
Grete is often introduced simply as “RG3 wife” in headlines, but she built an athletic identity of her own long before she met Robert Griffin III. Her Estonian roots and competitive background remain a big part of who she is today, and she has continued to represent Estonia in international heptathlon competitions even after settling in the United States.
Grete Griffin’s Career & Professional Life
Professionally, Grete Griffin is a heptathlete — an athlete who competes in seven combined track and field events, including sprints, hurdles, jumps, and throws. It’s widely considered one of the most demanding disciplines in athletics because it tests speed, strength, and endurance all at once.
Grete’s competitive résumé includes a strong showing at the 2010 World Junior Championships in Moncton, Canada, where she placed fourth with a personal-best score at the time. She also competed at the 2012 World Junior Championships in Barcelona, Spain, finishing ninth. One of her career highlights came at the 2015 European U23 Championships in Tallinn, Estonia, where she posted a personal-best heptathlon score of 5,813 points and finished fifth.
While competing at Florida State, she balanced training, competition, and academics — a common challenge for student-athletes representing their home countries internationally. Her career slowed somewhat as she started a family with Griffin, but she has remained connected to the sport and to Estonian athletics.

The couple moved quickly. Reports at the time noted the two getting matching tattoos and being seen together publicly, including a trip to Los Angeles. Their relationship deepened over the following months, and the pair welcomed their first daughter together, Gloria, on July 2, 2017.
Just before their daughter’s birth, RG3 and Grete became engaged on May 13, 2017. The engagement and the arrival of their daughter happened within weeks of each other, marking a fast-moving and eventful chapter in their relationship.

The family has been visible at Griffin’s public appearances over the years, including during his final NFL seasons, when Grete and their children were regularly seen supporting him from the stands.
