Duos come in all shapes and sizes, and often rely on a symphony of opposites.

In honour of the London Duathlon we’ve collected our favourite duos of all time to help inspire you to take on this double act event. 


In a story of sisterhood, this classic pair from the 90s namesake film Thelma & Louise go on the run together. The idea of two lead female fugitives was radical at the time, causing the film to be heavily debated. 


Cheese-chomping chums Wallace and Gromit - a clumsy inventor and his silent canine companion - take on some cracking adventures together. From criminal penguins and mechanical trousers to a murder mystery in a bakery, whatever happens, Gromit is usually there to save the day. 


Burger and chips – a classic combo that no one can deny! You simply can’t have one without the other. 


Sonny & Cher – the all-singing, acting and presenting married duo – spent a decade together making hits like I got you babe’, starring in films, presenting their own show and selling 40 million records worldwide. 


Funny female duo French and Saunders had twenty years together spoofing everything from Madonna, Harry Potter and Catherine Zeta-Jones to America’s Next Top Model. Check out their Titanic spoof in the video above.  


Ant & Dec met at the age of 14 as PJ & Duncan on the children’s TV series Byker Grove. They became best friends and have grown together since to become award-winning TV presenters. To make sure they aren’t mistaken for one another, they have always followed the 180-degree rule. Let’s get ready to rumble!!


The original slapstick comedy duo from the 1920s - Laurel and Hardy, Laurel the lumbering friend to haughty Hardy. They are known all over the world for their humour, but often under different names like ‘Flip and Flap’ in Poland. 


The ever popular Nintendo's Super Mario Brothers Mario & Luigi make a great family duo. This unlikely high-performing pair of little and large Italian plumbers spend their day’s drag-racing, collecting balloons and trying to rescue Princess Peaches. An adventure so big, you'll need both Bros.!


An unlikely pair, Sam and Frodo are a good foil for each other – necessary on such an epic journey! Although their patience was tested and challenged, they made it to the end by having one another. 


The original dynamic duo, Batman and Robin have been gracing our screens since the 60s and comics since the 40s! A pair that have stood the test of time while fighting crime with a series of BANG! KAPOW! and Holy smokes Batman!, one is not quite the same without the other.

Variety is the spice of life

Much like Batman and Robin – what is a run without a cycle? Pairing the two can make such a challenge more fun to complete. Variety is, after all, the spice of life. And with training advice, heaps of fundraising support and a sponsorship target of just £325, you can’t go wrong!

There’s a choice of distances, and if you only fancy one part, you can of course do a team relay instead.
