What is the London 50-hour Improvathon?

The 11th Annual London 50-Hour Improvathon

‘Absolutely incredible. This isn’t theatre – it’s blood sports! WhatsOnStage ∗∗∗∗∗

‘Hilarious! Like nothing you’ve ever seen before. Late night clubbers and early morning joggers unite!’
Time Out Critics’ Choice

London’s 50-hour improvised comedy soap opera starring some of the world’s leading improvisers is back and sparklier than ever! This year’s epic takes us to 1980s Blackpool and The World Ballroom Dancing Championships… It’s Strictly like you’ve never seen it before! Expect big hair, big outfits, big dramas and huge laughs.

Starting at 7.00pm on Friday 9th February 2018, The Improvathon plays in two-hour episodes continuously until Sunday 11th February at 9.00pm (yes, that’s right through both nights!).


Playing annually since 2008, this theatrical marathon gathers some of the funniest performers from all over the world to appear as guests (dropping in for a few hours) or as main characters going the whole 50 hour mind-bending sleep-defying distance. After 30 hours without sleep, performers become too tired to censor themselves – hilarious, unpredictable, and unlike anything else, this is theatre at its most exciting.


You can drop in for any 2-hour episode or buy a full 50-hour event pass for only £65 (£55 if you book before Christmas 2017).

There’s also a special ‘Family Episode’ on Sunday 11th February at 11.00am, which is suitable for kids of all ages!
