7 things not to miss at the Cancer Research UK London Summer Run

This year we put a sunny spin on the UK’s most popular 10K – Cancer Research UK London Winter Run – with an exclusive one-off Summer special. Introducing the inaugural Cancer Research UK London Summer Run!

Our Cancer Research UK London Winter Run is infamous for its fun route activations and party atmosphere, so the Cancer Research UK London Summer Run will be no different. Here are 7 things to look forward to on Sunday 5th September 2021…

Flamingo Flamboyance Frenzy

Our iconic penguins are back for a long overdue beach holiday. Listen out for feelgood summer classic tunes as you head into the craziest beach party London has ever seen.


Penguin Beach Party

Brand new for 2021, our flamingos will be out in full force to cheer you on and show some pink pizazz.


Awesome Medal

Exclusive one-off medal for our summer run, we’ve gone bright and bold with our inaugural medal.


Lifeguards & Sharks

Some jawsome entertainment here, with our friendly sharks and team of lifeguards. All Baywatch-esque slow-motion running is encouraged here!



Loads of live music

We’ve lined up some of our greatest hits from previous years and scattered them around the route. Keep an eye (or an ear) out for the Rock Choir, Drumworks, Pantasy Steel Band and Capital Connections.


World Famous Landmarks

You’ll see London in a new light as you run past famous landmarks such as Nelson’s Column, St Paul’s Cathedral, The Gherkin and more. Keep an eye out for Boris as you will be finishing outside Downing Street.


A safe return to running

Running events are back! We have worked very hard to ensure that this is a safe and comfortable experience for all. We have worked with local councils and stakeholders to implement a variety of measures that will ensure that runner safety is paramount.
