Helen Glover undecided about Tokyo 2020

The 30-year-old Penzance athlete won Great Britain's first gold of London 2012 with Heather Stanning in the women's pair.

And they repeated the feat four years later, claiming gold in Rio last August.

Stanning, a major in the British Army, has since retired, but Glover is considering her options and contemplating continuing for a third Olympics.

"Right now I haven't made a decision about rowing or not. I think I might go back into training for a few days and see if that helps," said Glover.

"In my mind I'd always had Easter as a point I'd wanted to have decided by, but that was plucked out of the air, really.

"I don't know what is going to make the decision happen. That's why I've decided I'll go back into training. There needs to be some sort of catalyst into making that decision. As yet, no light bulb moment has happened.

"I've tried not to think about it too much. Maybe thinking about it a bit will be the way I make my decision.

"I've already achieved what I wanted to from sport, which was Olympic gold and to go back I have to know I'm really going to enjoy the journey having achieved what I wanted to achieve."

British Rowing has not applied any pressure with any deadline for Glover to make a decision, but she wants to draw a line and move on in one direction or another.

She has been keeping herself fit and took part in the Devizes to London kayak race with husband Steve Backshall, the television wildlife expert she married last September.

They won the mixed event. And a week later she completed April's London Marathon in an impressive three hours five minutes, 27 minutes quicker than Stanning.

Glover added: "Part of the reason I wanted to take these challenges on - the kayak, the marathon and things like that - was because I need to be fit enough to keep that decision alive.

"My general fitness is the best it's ever been, but the specific fitness for rowing is down a bit, because I haven't been rowing.

"If I went back it could possibly work really well in the long term, because that general base fitness that I've worked on this year is obviously quite high."

Stanning's retirement last autumn will not impact on Glover's final thought process. The pair enjoyed a five-year, 39-race unbeaten run, but Glover won world gold in 2013 with Polly Swann when Stanning took a rowing sabbatical to tour Afghanistan on army duty.

Glover added: "If she was staying on it would've made me more likely to stay.

"But I always knew she wasn't staying on, so it was never a factor. In 2013 when she left, she didn't know for sure whether she was coming back and that was not a factor at all for me. I was always going to carry on.

"I do know what it's like to row without Heather. I do know I can be in a successful partnership without Heather, so those things haven't affected my decision.

"However, I loved rowing with her. It was an amazing experience. Aside from the results, the journey was great, with Robin (Williams, their coach) as well.

"Without those two around at the moment, I know the journey will be very different."
