KatrÃÂn Tanja DavÃÂðsdóttir (; born 10 May 1993) is an Icelandic former CrossFit athlete known for her ten appearances at the CrossFit Games. That was from 2012 to 2023, with the exception of 2014 and 2022. She is the women's champion of the 2015 and 2016 CrossFit Games. KatrÃÂn is the second woman to repeat as champion, following in the footsteps of her countrywoman, 2011 and 2012 CrossFit Games champion AnnÃÂe Mist ÃÂórisdóttir.
KatrÃÂn has a background in track and gymnastics. She became interested in CrossFit when she saw AnnÃÂe Mist ÃÂórisdóttir win the 2011 CrossFit Games. She first qualified for the CrossFit Games in 2012 where she finished 30th. She also qualified for the 2013 Games.
KatrÃÂn missed qualification in 2014 due to a relatively poor performance at the Europe Regional on Event 5, a combination of legless rope climbs and sprints. KatrÃÂn finished in the top 10 on every 2014 Regional Event except this one, in which she dropped to 24th. In the end, 9 points separated KatrÃÂn from the final 2014 Games qualifier out of the Europe Regional, third-ranked Norwegian athlete Kristin Holte.
KatrÃÂn has said that missing qualification in 2014 was the "differentiator" that helped her come back to the Games and win in 2015.
Katrin's only event win at the 2015 Games came in the final event, Pedal to the Metal 2, but that was enough to move her ahead of countrywoman Ragnheiður Sara Sigmundsdóttir, who had been in first place going into the last two events.
At the 2016 CrossFit Games, KatrÃÂn won 3 events: Double DT, Handstand Walk, and The Plow. She beat off a challenge from Tia-Clair Toomey to become the 3rd athlete (after Rich Froning and AnnÃÂe Mist ÃÂórisdóttir) to have repeated their win at the Games.
At the 2017 CrossFit Games, KatrÃÂn managed two wins, Strongman's Fear and 2223 Intervals. In a tightly fought Games, she ended up in 5th place overall.
In 2018, KatrÃÂn finished 3rd behind Tia-Clair Toomey and Laura Horvath.
In 2020, KatrÃÂn received an invitation to the Games. In the Covid-19-affected season, KatrÃÂn won two events and finished fourth in Stage 1 to become one of five female athletes who can compete in person at the ranch in Aromas. At the Stage 2 of the Games, in a much-reduced field dominated by Tia-Clair Toomey, she managed one event win and returned to the podium, finishing in 2nd place.
In 2022, KatrÃÂn failed to qualify for the CrossFit Games after finishing sixth at the Games semifinal Strength in Depth, and then third in the Last Chance Qualifier.
KatrÃÂn qualified for the 2023 CrossFit Games after finishing second in the North American West semifinal. At the Games, she performed poorly in the Pig Chipper event, but came 2nd on two events (Cross-Country 5K and Echo Thruster Final), finishing up in 7th place overall.
KatrÃÂn withdrew from the 2024 season due to a back injury and underwent surgery.
In December 2024, KatrÃÂn announced her retirement from competitive CrossFit.
KatrÃÂn started doing CrossFit in September 2011 at the age of 18. She had 10 years of training as a gymnast as well as 1 year of competition experience in track and field (athletics).
From 2016 to 2021, she trained under coach Ben Bergeron (CompTrain) at CrossFit New England in the United States of America. Prior to this, she trained at Reebok CrossFit Reykjavik, in Reykjavik, Iceland, and CrossFit Stodin. In 2021, Katrin left CompTrain and moved to train at Reebok CrossFit Reykjavik under coach Jami Tikkanen. After failing to qualify for the 2022 CrossFit Games, she moved to Mat Fraser's HWPO training camp.
KatrÃÂn appeared on the 30th season premiere of The Amazing Race, where she asked teams to identify two national tonics: BrennivÃÂn and ÃÂorskalýsi.
KatrÃÂn's grandfather is Helgi ÃÂgústsson, the former ambassador of Iceland to the United States.
In 2021, it was announced that she was in a relationship with former Canadian ice hockey player, Brooks Laich. They announced their engagement in December 2024. Their daughter Emberly Heba was born in October 2025.
