Blaynes Lifestyle: Elen Rivas shows off her VERY toned figure in a sexy black bikini

She recdntly completed the London Marathon in a very respectable five-and-a-half hours and is clearly keen to show off the results after her months of training.

Mother-of-two Elen Rivas looked stunning as she lounged by the pool of her hotel in Barcelona, Spain, wearing a sexy black monokini which flattered her toned curves and highlighted her lithe figure.

There were no signs of any lumps or bumps as Elen made the most of the sunshine on her well-earned trip, pulling off the notoriously difficult-to-wear monokini with aplomb.

So it's no wonder the 35-year-old model, who recently said she's in the 'best shape of my life', attracted a few admiring glances as she sauntered casually around the pool and cooled off with a dip in the swimming pool.

And if Elen was aiming to make ex-boyfriend Peter Andre jealous with her sexy poolside outfit, she has surely succeeded.

The pair split this month after five months of dating, and 38-year-old Peter recently insisted he will work hard to stay friends with the Spanish star.

He told heat magazine recently: 'We're mates, and if we had stayed together that could have been ruined. We never argued and if the relationship had continued, we would have started to row.

'We never saw one another. I am so busy and so is Elen, and in my heart, I knew that the relationship was never going to step up to the next level. We weren't going to get married. We are better off as friends - and we are.'

And Peter stayed true to his word when he encouraged fans on Twitter to sponsor Elen in her London Marathon bid.

Elen completed the Marathon in aid of the charity Wellbeing of Women, and told her followers on Twitter she found the whole experience very emotional.

She tweeted: 'Hiya,what an amazing day was yday at the marathon.The atmosphere was superb. I must say it was incredible seeing a all that people running.

'Finally I got in the finish line after 5.5hrs with 2 massive blisters in my big toes..I feel like a truck has run over me..lol.'
