We are looking forward to welcoming you tomorrow! Just a friendly reminder:

The best postcode to navigate to the event is: BN20 7XL - this is a new event site for 2021.

We recommend arriving at the event 30 minutes prior to your start time.

There is no spectating at this event. Please make sure any supporters you may have are aware of this.

2000, Monday 12.04.2021

Participant email "Sussex 2021 - Your start time" is currently being processed. You will receive this in your inbox this evening. A non-personalised copy of this email can be seen here. NB You can also find your participant details (number, start time) by logging in here.

1500, Monday 12.04.2021

Just a gentle reminder: this year's event will be hosted from the Helen Garden (BN20 7XL), to the West of Eastbourne and NOT from Birling Gap as it has been in previous years.

1600, Friday 09.04.2021

Participant numbers and timing chips have been posted out today. Please expect these to arrive on your doormat by Tuesday. A final update email (originally scheduled for today) will go out early next week, within which will be included your individual start time. With best wishes.

1000, Tuesday 30.03.2021

New start / finish venue for 2021! This year's event will be hosted from the Helen Garden (BN20 7XL), to the West of Eastbourne. This site provides easy access onto The South Downs and is within walking distance of Eastbourne (mainline) train station.

2000, Thursday 25.02.2021

This event will now take place on Saturday the 17th of April 2021. Please await a personalised email from us before contacting us with any individual questions.

1900, Tuesday 23.02.2021

The time table announced yesterday by the UK Government is great news as it allows for outdoor organised sports in England to restart from the 29th of March (*1). Big cheer! Unfortunately the date is just 9 days later than we would have all liked. Consequently this event can not take place as originally scheduled on the 20th of March 2021.

We are currently in consultation with key-holders to finalise the new date.

We will be emailing all registered participants by the end of this week with full details of the new date and all available other options. We kindly ask that you do not individually contact us before you have read this email.

(*1) Such activities will have to conform to the prevailing social distancing measures on gatherings of groups (within an event / activity setting).

1000, Tuesday 12.01.2021

Re the current national lockdown: We will be waiting until the government's mid February announcement before making a decision on whether this event is postponed or can continue as scheduled. If the event is postponed then the currently favoured contingency date is: [date now removed to avoid future confusion].

1100, Thursday 10.12.2020

Check-in! [New] : We will be asking all registered participants to check in online approximately two weeks from the event. The Check-in process will result in a simpler event experience for you by removing the usual on-the-day administration. Within the Check-in process we will ask you to: 1) Confirm your preferred postal address to enable your participant number and electronic timing tag to be posted out, 2) Watch the mandatory event safety video and 3) Give us an indication of your preferences with regards to a mass start or an individual time-trial start.

With the world famous Seven Sisters, and far reaching views out over the English Channel, these courses are already attracting international recognition. The Sussex 10K, half, marathon and ultra routes shoulder the coastal towns of Eastbourne and Seaford, which lie to the eastern section of the South Downs National Park. Where the land meets the sea, the results have produced one of the most iconic coastal landscapes of Britain - vast cliffs of brilliant white chalk.

Based from one of the few coastal access points on this coast, Birling Gap is perfectly positioned for runners to explore this dramatic cliff ridden coastline. Expect a few ups and downs as you negotiate that beautiful rolling downland!

Virtual : Don't forget to connect with us via the official Facebook Event where you can select "Going" or "Interested". Here you can network with others and join in the conversation by asking questions and advice.

In Person : Unfortunately we are not able to offer a post event gathering or party this year.

Never be locked in

  1. Cancellation: You will always be given a full refund (no fees or charges) if the event has to be cancelled due to Covid-19. Your entry will never be ‘rolled over’ to a subsequent year unless you want it.
  2. Postponement: You will always be given the following three options should an event have to be postponed (date changed) due to Covid-19. You will have one week from the date the event is postponed to make your choice:
    1. Accepting the new event date (this is the default option if you make no choice).
    2. Transferring to one of our other event locations for any date in the future.
    3. A refund (less a booking & card processing fee which will never be more than £10).
  3. If your plans change or you simply change your mind:
    1. You can receive a full refund (no fees or charges) should you change your mind within 30 days of booking (*1). No questions asked. To do so; log onto your account > Orders > Select the desired order number > Cancel > Confirm. It’s as simple as that. (*1 for bookings made more than 3 months prior to the event).
    2. You can chop and change between our whole events portfolio at any time. Just make sure you do this more than 30 days before the event you are booked on to. To do so; log onto your account > Orders > Select the desired order number > Change > Select the desired (new) event.
  4. A change in the tier system prohibiting travel or participation: If you can't attend due to a last-minute local lockdown where you live then you can opt to move your event entry to another event at a later date. If this is after the online change window closes (30 days prior to the event, point 3.b above) then this request must be instructed via email (see Contact page) with proof of address provided (a redacted cover page of a utility or council tax bill or similar):
    1. No later than 48 hrs before the event date and,
    2. No later than 7 days after a planned local lockdown has been announced (failure to do this limits our ability to offer your entry space to someone on our waitlist who is not in a restricted area).

Never be within 2 meters of anyone else

  1. No event staff will come within 2 meters of any participants:
    1. RFID electronic timing removes the need for close personal contact.
    2. Checkpoints (aid stations) operate on a self-serve basis; all items will be individually bagged / bottled with gloved staff keeping their distance but there if you need them.
  2. Receive your participant number and electronic timing chip in the post ahead of time or collect on the day, your choice.
  3. Watch the event Welcome and Safety Video online 24hrs before the event from your phone or laptop.
  4. Join in with our mass start or choose a time-trial start for yourself or your group. Either way you can enjoy watching the online leaderboard update throughout the event day to see how you fare against the competition.

Although there are a raft of other changes we have put in place we hope the examples above clearly demonstrate our priorities to you. All changes will be in place across our portfolio of events for the foreseeable future, most likely until the end of 2021.

We hope that you can now relax and take part with confidence; we are looking forward to delivering your next tough challenge!

With best wishes,

James and the Endurancelife Team.
