Chris Knierim

Early career

Knierim started skating at age 12.^[4] He began a partnership with Brynn Carman in February 2006.^[7] They were coached by Dalilah Sappenfield in Colorado Springs, Colorado.^[4] The pair won the novice national title at the 2008 U.S. Championships and the junior silver medal at the 2009 U.S. Championships. They announced the end of their partnership on April 9, 2009.^[7]

Knierim began skating with Carolyn-Ann Alba in 2009. They won the junior pairs title at the 2010 Midwestern Sectional Championships^[8] and the junior pewter medal at the 2010 U.S. Championships, after which they parted ways.

Knierim began a partnership with Andrea Poapst in July 2010.^[9] They won the junior title at the 2011 Midwestern Sectional Championships and the junior silver medal at the 2011 U.S. Championships. Poapst/Knierim won gold at the 2011 Ice Challenge, their first senior international together.^[10] They parted ways at the end of the 2011–2012 season.

Teaming up with Alexa Scimeca and 2012–2013 season

Coach Dalilah Sappenfield suggested that Knierim skate with Alexa Scimeca. They teamed up in April 2012.^[11] They decided to train with Sappenfield, Larry Ibarra, and various other coaches at the Broadmoor World Arena in Colorado Springs, Colorado.^[12]

Scimeca/Knierim won the gold medal at their first international event, the 2012 Coupe de Nice in October.^[11] After a number of withdrawals by other teams, they received a Grand Prix assignment, the 2012 NHK Trophy in November, where they placed fourth.

The pair won the silver medal at the 2013 U.S. Championships in January. They were assigned to the 2013 Four Continents Championships but withdrew just before the event when Scimeca injured her right foot in practice.^[13] Scimeca/Knierim were named to the U.S. team for the 2013 World Championships after Caydee Denney / John Coughlin withdrew.^[14] They placed ninth in their World Championships debut in March.

2013–2014 season

Scimeca/Knierim experienced a setback that hampered their season when Knierim broke his left fibula in July. He underwent surgery that placed a metal plate and nine screws in his ankle.^[15] While Knierim was able to heal relatively quickly, the team believed they rushed back to competition a bit too soon. In January, they won the pewter medal at the 2014 U.S. Championships and were named second alternates to the 2014 Winter Olympic team. They then won the bronze medal at the 2014 Four Continents Championships. Their second place short program score of 66.04 set a new record for the highest score ever achieved by a U.S. pair team. Knierim had additional surgery in March to remove the metal hardware in his leg, which had been causing discomfort.^[16]

2014–2015 season: First national title

Scimeca/Knierim won the gold medal in their first ISU Challenger series event at the 2014 U.S. International Figure Skating Classic and won the bronze medal at 2014 Nebelhorn Trophy. They were assigned two Grand Prix events, placing fourth at both 2014 Skate America and 2014 Trophée Éric Bompard.

At the 2015 U.S. Championships, Scimeca/Knierim captured their first national title, setting new U.S. record scores in both the short program and the free skate. They also became the first American pair team in history to perform a quadruple twist in competition.^[16]

At the 2015 Four Continents Championships, Scimeca/Knierim placed fifth and earned new ISU personal best scores of 124.44 in the free skate and 187.98 total, setting new records for the highest scores ever achieved by a U.S. pair team in an international event. At the 2015 World Championships, the pair placed 7th, the highest finish by a U.S. pair since 2011. They then competed at the 2015 World Team Trophy, finishing 4th in the short program and 3rd in the free skate, which ultimately helped Team USA win the gold medal. Scimeca/Knierim earned new personal best scores of 127.87 in the free skate and 192.09 total, setting new records once again for the highest scores ever recorded by a U.S. pair team in international competition.^[17]

2015–2016 season: First Grand Prix medals and silver at Four Continents

Scimeca/Knierim began their season at 2015 Nebelhorn Trophy where they won the silver medal behind reigning Olympic champions Tatiana Volosozhar / Maxim Trankov.^[18] The team then competed at 2015 Skate America where they won the silver medal. They earned a new personal best short program score of 69.69, setting a new record for the highest score ever achieved by a U.S. pair team in international competition. The following week, they won the gold medal at 2015 Ice Challenge in Graz, Austria.

Scimeca/Knierim went on to win the bronze medal at 2015 NHK Trophy which helped qualify them for the 2015–16 Grand Prix Final in Barcelona, where they placed seventh. They were the first U.S. pair since 2007 to qualify for the Grand Prix Final.^[19] The pair entered the 2016 U.S. Championships as the heavy favorite for the title, but won the silver medal after costly errors.

At the 2016 Four Continents Championships, Scimeca/Knierim won the silver medal in their best competitive outing to date. ^[20] They earned new personal best scores of 140.35 in the free skate and 207.96 total, which are the highest scores ever recorded by a U.S. pair team in international competition.^[17] A subsequent injury to Knierim limited the team's training before the 2016 World Championships, where they placed 9th. They were 7th in the short program with a personal best score of 71.37, which set a new record for the highest score ever achieved by a U.S. pair team in international competition.^[17] The pair then competed for Team North America at the inaugural 2016 KOSÉ Team Challenge Cup, where the team won the gold medal.

2016–2017 season: Major illness, surgery, and successful return

Alexa Scimeca Knierim became sick in April 2016, and her illness interrupted the Knierims' training throughout the summer months. She was properly diagnosed with a rare, life-threatening gastrointestinal condition in August and underwent two abdominal surgeries that month.^[21][22] The pair resumed light training in late September.^[23] Scimeca Knierim underwent additional surgery on November 1 and returned to training by the middle of that month.^[21]

Scimeca Knierim's illness involved regular episodes of vomiting, debilitating pain, difficulties with sleeping, eating or drinking, as well as significant weight loss.^[21] Already small, she lost 20 pounds and shrunk to just over 80 pounds.^[24][25] Knierim stated that when his wife initially returned to the ice following surgery, she had to hold his hands just to skate a lap around the rink and could only skate for 10 minutes before having to go home for a nap because it was so physically draining on her body.^[26] The pair withdrew from both of their Grand Prix events, the 2016 Rostelecom Cup and 2016 Cup of China, and the 2017 U.S. Championships. They resumed full training in January^[27] and were named to the U.S. team for both the 2017 Four Continents Championships and the 2017 World Championships.

In February, the Knierims made a strong return to competition at the 2017 Four Continents Championships, where they placed sixth in a deep field of Chinese and Canadian pairs. Their total score was the second highest score ever achieved by a U.S. pair team, behind only their score from Four Continents the prior year. The pair then competed at the 2017 World Championships, where they skated two strong programs and placed 10th in an exceptionally deep field. 5th through 10th place were separated by just 4.35 points. They placed 8th in the short program with a personal best score of 72.17, the highest score ever achieved by a U.S. pair team. They were the only U.S. pair to qualify for the free skate. Their total score of 202.37 is the second highest in U.S. pairs history, and they are the only U.S. pair to have ever surpassed the 200 point barrier.^[28] This was the Knierims' fourth top 10 finish in their four Worlds appearances. They are the only U.S. pair in the past five years to have earned top 10 finishes at the World Championships.

2017–2018 season: Second national title and Pyeongchang Olympics

The Knierims began their season at the 2017 U.S. International Figure Skating Classic, where they won the silver medal and were narrowly edged by Canadians Kirsten Moore-Towers and Michael Marinaro. They placed 1st in the free skate after having changed their long program in the week prior to the event.^[29] The team then competed at two Grand Prix events, 2017 NHK Trophy and 2017 Skate America, where they placed a solid fifth in deep fields at both events. It was revealed after Skate America that Chris Knierim was recovering from a patella injury.^[30] The Knierims have been the top U.S. finisher at every international event they have entered for the past three years. Their scores throughout the Grand Prix season were the clear highest by a U.S. pair team.

At the 2018 U.S. Championships, the Knierims won their second National title with a score of 206.60. They placed 1st in the short program, 1st in the free skate, and performed a quadruple twist in competition for the first time since 2016. They are one of the only pairs in the world capable of doing a quad twist. Following the event, the Knierims were named to the 2018 U.S. Olympic Team that competed at the 2018 Winter Olympics in Pyeongchang, South Korea. They were the sole U.S. pair team at this Olympic Games.^[31]

At the 2018 Winter Olympics, the Knierims won an Olympic bronze medal in the figure skating team event as a key part of the U.S. team. They placed a strong 4th in the short program with a season's best score, and placed 4th in the free skate. Their total score was the highest of their season. In the pair event, they were 14th in the short program and finished 15th overall in what was the strongest Olympic pair competition to date. In the free skate, the Knierims became the first U.S. pair, and the second pair ever in history, to successfully perform a quad twist at the Olympics.^[32]

Weeks later, the Knierims competed at the 2018 World Championships. They placed 11th in the short program with a strong performance and finished 15th overall after an uncharacteristically shaky skate by Alexa that included a fall on a death spiral. They were the only U.S. pair to qualify for the free skate.

On May 14, 2018, U.S. Figure Skating announced that the Knierims had left their coach, Dalilah Sappenfield, to train with 2018 Olympic champion Aljona Savchenko and her coaching staff. They will train part-time in Oberstdorf, Germany.^[33]
