When you're a world-class athlete, young and fit, it's a no-brainer that you would gravitate towards a like-minded partner.
It's no secret that the Olympic Village is a hotbed for romantic trysts - with use of Tinder rising dramatically, and reports that Rio 2016 organisers have ordered in a record 450,000 condoms for the athletes.
However, it's not always about the short-term fling. We've picked out some of the longer-term Team GB romances that will melt your heart.
Siobhan O'Connor and Chris Walker-Hebborn (swimming)
The Bath-based swimmers are a long-time couple. Walker-Hebborn is the tattooed north Londoner and O'Connor was born in Bath and raised in Keynsham, south of Bristol. She made her Olympic debut at London 2012, aged 16.
They are incredibly cute, posting adorable couple pictures on Instagram showing that they scrub up particularly well out of the pool.
O'Connor won silver in the pool, and Walker-Hebborn was quick to congratulate her on Twitter.
Kate Richardson-Walsh and Helen Richardson-Walsh (hockey)
The pair tied the knot in 2013, the year after winning bronze in the London Olympics, and became the first married gay couple to compete at the Games. This is skipper Kate, 36, and 34-year-old Helen's fourth Olympics together.
They've been team-mates for almost two decades, a couple for eight years and married for three - not bad going at all.
Chris Adcock and Gabby Adcock (badminton)
The Adcocks, one of the favourites for gold in the mixed doubles, married in 2013 and it has proven to be a match made in heaven. They won the first tournament they competed in on returning from honeymoon and went on to take gold at the Glasgow Commonwealth Games in 2014.
The couple have been together for over 10 years, and being team-mates would make combining their schedules a lot easier.
Michael Rimmer and Eilish McColgan (athletics)
As they say, those who train together, stay together (or something like that).
Rimmer, the 800m runner from Southport, is a former European Championship silver medallist and will race at his third Olympics. McColgan, whose mother Liz won Olympic silver and world gold over 10,000m, has battled back from injury to qualify for Rio in the 5,000m.
Liz has even been training the couple together, which adds to the cute factor.
Jason Kenny and Laura Trott (cycling)
The ultimate golden couple, with five golds between them, made their relationship public while watching beach volleyball with David Beckham at London 2012. It prompted one observer to say British Cycling had thought of everything to produce champions. They are engaged.
