Olympic medallist Kristina Groves to announce her future in speed skating

CALGARY - Speed skater Kristina Groves will reveal her future plans in the sport at a news conference Wednesday.

Groves crashed and suffered a concussion in a World Cup race in November 2010, which put an end to racing for the rest of the season.

The 34-year-old from Ottawa has won three Olympic silver medals and a bronze as well as 18 world championship medals during her career.

She declined to state what her plans are, when contacted Monday by The Canadian Press.

Groves will make a "major announcement" at Calgary's Olympic Oval, where she has trained for the last 16 years. Her coach Xiuli Wang, Speed Skating Canada chief operating officer John-Paul Cody-Cox and members of the national team are scheduled to attend.

Groves said in a blog posting earlier this month she occasionally still suffers post-concussion symptoms, but believes the worst is behind her.

She also said she's been mountain biking this summer when she normally would be doing dryland training for the upcoming speedskating season.

Groves won a silver medal in the 1,500 metres and bronze in the 3,000 at the 2010 Winter Olympics in Vancouver and Whistler, B.C. She also won a world championship in the 3,000 metres in 2008.
