Helen Glover and Heather Stanning undecided about defending their Olympic title

Double Olympic rowing champions Helen Glover and Heather Stanning are in no rush to decide if they will defend their crown at the 2020 Games in Tokyo.

Coached by Welshman Robin Williams MBE, the reigning European, world and Olympic coxless pair champions are on an unbeaten run stretching back five years and almost 40 races.

"I think it's really important we sit back and acknowledge what we have achieved and enjoy the moment," Stanning told Tuesday's Sportswomen show on Sky Sports News HQ.

"I think all three of us - Robin included - know we just want to have a year where we kind of acknowledge what we've done in the last six years. When we make the decision it's got to be the right decision.

"If we go to Tokyo, we are going to go there to defend a double title and that will be something different, not something anyone has done before, so we need to make sure we make the right decision."

Glover puts the duo's domination in their event down to a constant desire to keep getting better under the tutelage of Williams.

"We have an ultimate desire to win and to win at the Olympic Games was our goal but what really drove us was how good we know we can be as a crew, regardless of what anyone else was doing," Glover said.

"Robin our coach was a huge driving force [behind our success].He's been with us for every one of our races and his coaching was crucial."

Stanning, who served in Afghanistan with the Royal Artillery, is due to return to the army later this year, while Glover revealed she is a little daunted as she prepares for a new challenge of her own.

"I'm getting married in a couple of weeks," Glover said.

"It's been nice because it's given something to think about and plan for but I'm not much of a planner so this is a difficult time for me!"
