We’re pleased to confirm that we’re hoping to offer carefully adapted, smaller and simplified events from September onwards.
Following updated guidance from the UK Government and the governing bodies who license our events - UK Athletics and British Triathlon - we’re working on the details to determine which events could safely take place. There’s a quick reference list on what we know so far at the bottom of this page but if you see an event open for entry on our website it means we are planning for that event to take place.
We know how important races and organised runs are to every runner. We understand that for some, the return of events can’t come soon enough. For others, taking part in an event still holds significant concerns.
It’s not going to be quite like it was before. Things will have to be a little different for a while. But the benefits of committing to a goal, running with others and that finish line feeling will be all the greater for the recent challenges we’ve all overcome.
Specific details on each of our events
We’re carefully adapting our event plans – from getting there to going home. We’re thinking through every detail that makes events feel great to work out what the safer alternatives are. Whilst the specific details for individual events are changing, all events will incorporate a range of fundamental changes to ensure a socially-distanced and contact-free event, the details of which are summarised below. Sadly, it is likely that some events will not be possible under these new requirements and in those cases we’ll announce their cancellation and explain why. Each event is different, so where they do go ahead we’ll explain what’s changed and why it’s all in place to keep everyone safe. We’ll also summarise everything you need to know in a final ‘Event Information’ email, sent a few days before your event day. If you have a question before entering, we’re here to help.
What to expect at events that go ahead:
Small and scheduled staggered/rolling wave starts
Contact-free registration with race pack by mail.
Simplified bag drop measures where available
Covid-secure water stations although self-sufficiency is advised Safe pick-up for medals and snacks
Bookable time windows from getting there to going home to control capacity.
Thank you for your support and understanding over these four months. We’ve missed you! That finish line feeling will be worth the wait. #SeeYouOnTheStartLine

Fuel and water stations will be placed every 2 miles.
Pacers, mile markers and chip-timed results will make it as easy as possible to get your pacing right, so that you can focus on your run and practice refuelling and rehydrating during a race.
Subject to availability, we expect pacers to be running at least the first 16 miles, clearly marked with target marathon times between 2h45m and 5h30m.
Not sure on which distance you should run? Don't worry, all three of 16, 20 or 24 miles have the same entry fee and you can change your mind at any time. Prior to Sunday 21 March, you can drop us an email but otherwise just tell us at the event - before the race at registration or, if you change your mind mid-race and decide to run one or two laps more/fewer than planned, as soon as you finish.
Take this opportunity to rehearse your:
- race day nutrition
- race preparation and travel
- running in a busy race situation with a marked out course that is new to you
- running in all of your marathon race kit
- race rehydration and refuelling
- recovery and strengthening
