Here at Guinness World Records London HQ, we're getting swept up in the romantic spirit of Valentine’s Day.
 
But rather than sharing flowers or chocolates this February 14, we’ve created a top 10 bouquet of the most heart-swooning, romance-inducing world records in existence.
 

Oldest married couple to complete a marathon on each continent (aggregate age)

 
Just a few days after Valentine’s Day 2015, Cathie, aged 61, and Troy Johnson, 68, set a record for the oldest couple to run a marathon on all seven continents. They have a combined age of 129 years 109 days.
 
The inspiring couple from the US set off on 8 February and over the following 11 days ran marathons together in Australia, the United Arab Emirates, France, Tunisia, the United States, Chile and Antarctica. #RelationshipGoals

Fastest wedding chapel

 
In 2010, Rev. Darrell Best of Shelbyville, Illinois, USA, converted his 1940s fire truck into a wedding chapel on wheels.
 
Dubbed 'The Best Man', the wedding venue allows lovers to tie the knot while they're on the road and is capable of reaching speeds of 99 km/h (62 mi/h).
 
Rev. Best, who has married over 40 couples in the vehicle, says that people love it because "it allows them to get married in any environment they want.”

Paulo Gabriel da Silva Barros and Katyucia Lie Hoshino, both of Brazil, have been verified as having a combined height of just 181.41 cm (71.42 in). They became record holders back in September 2016 after tying the knot.

Speaking to Guinness World Records in November 2016, Katyucia said: “We may be short but we have big hearts and lots of love for each other as well as everybody in our lives. Our life isn’t without its challenges but we are so happy we can tackle these challenges together.”
