If you'd like to be the first to know when entries open for next year's event, sign up to our reminder service.


We have had to make the very difficult decision to cancel this year’s ULTRA LONDON event, due to take place on Saturday 31 July.  Unfortunately, a number of specific operational challenges relating to the delay in moving to step 4 of the Government's Covid-19 roadmap has put us in a position where we do not have the level of certainty required to progress with the event after discussions with a number of different stakeholders.

If you have entered the event, your full entry fee will automatically be refunded to the account you originally used to enter, this could take up to 21 days. You do not need to take any further action. 

We will be back in 2022 to finish what we started and we'd love to see you there. If you'd like to be the first to know when entries open for next year's event, make sure you sign up to our reminder service and we'll email you with further updates. Thank you for your understanding.
