An achievable 100 mile run!

We've been very fortunate to have been granted permission to hold a 100 mile ultra event at Samphire Hoe. A nature reserve created from 4.9 million cubic metres of chalk marl from the Channel Tunnel excavations on the coast of Kent near Dover.

2022 Runners Handbook - Click Here

It's our aim that this event makes an impactful difference to Samphire Hoe in a positive fashion and as such £5-£20 from each entry fee will be donated directly to the nature reserve to aid them in maintaining this lovely environment.

We want runners to achieve incredible things. The main event will be a 100 mile endurance run of 27 times 3.71 mile loops. In addition we'll hold 24 hour, 6 hour timed challenges on Saturday along with a Pacer Challenge to complete as many 3.71 mile loops as possible in the time limit chosen.

The course is a mix of very high quality gently rolling trail, bike paths and a nice dead flat sea wall, quite literally all within the shadow of the famous White Cliffs of Dover, there is some wild life to keep an eye out for, you'll be able to see what's going on at both Dover and Folkestone Harbours, there will no doubt be some ships to see and some trains to spot too for good measure! If its clear you can even see France!

We want runners to achieve incredible things and so we've set up this 100 mile run to be as achievable as possible. This event is ideal for first time 100 mile runners as we take away many of the issues with the bigger point to point 100 milers such as navigation or tricky terrain or for more experienced ultra runners looking for a quicker 100 mile time, or to hone ultra skills or simply to earn an ace buckle and top quality 100 mile finisher shirt. The key features are

1) A 32 hour time limit. Start is 0800 on Saturday 24th September. Cut off is 1600 on Sunday 25th September. (That allows an average pace of over 19 minutes per mile)

2) No navigation. It's a simple loop/out and back, the sea wall is solid and flat, the trail is high quality and slightly rolling to give the legs a bit of a different work out. We'd estimate the total elevation gain for the 100 miles to be about 2500'

3) No compulsory kit aside from lights required when dark

4) No large gaps between aid stations. You'll be able to get fluids/food/access your gear every 3.71 miles.

5) Get out of jail card. We appreciate that the reality of 100 milers is that not everyone finishes. You'll be able to drop down to the 24 hour event any time before 0800 on Sunday and receive an official finish, a Samphire Hoe Challenge medal and goody bag.

6) For 100 mile finishers there will be a kick-ass buckle and finishers shirt. And although we doubt you'll fancy it at the finish, a goody bag of course! The sub 24 buckle is above, the sub 32 buckle is the same design in all silver.

7) If you are a first time Samphire 100 finisher we'll have a "grey" Samphire 100 Finishers shirt for you. If you are finishing your second (or more!) Samphire 100 then - after the event - we'll organise a one off "Autumn" toned Samphire 100 Finishers shirt that we'll get to you 6-8 weeks after the event.

8) We always feel pacers get a raw deal at ultras, nobody ever knew they were there, we want to change that! For people supporting 100 Mile runners we have the Pacer Challenge. They can keep their runner company for as much or as little as they wish after 1700 on the Saturday, one lap and they are an official finisher, eight laps and they'll receive an official ultra finish. (We'll also have a 7 laps plus a small loop for folk who "just" want to run a marathon distance.) Thus they can keep runners company, be very much part of the event, they'll have their laps recorded, receive an official finish, receive a Samphire Challenge medal and a goody bag. (Please note that you cannot drive in to Samphire Hoe between 1830 Saturday night and 0700 Sunday morning, so please plan any pacers accordingly.)

9) There are no qualification requirements, we'll have on site medics and its simple logistics!

Please have a careful read through the FAQ section and consider joining us to earn what we hope will be the most impressive buckle you are able to earn in this side of the Atlantic.

Please note that this race falls outside of our "Fair Runner Policy" due to the far larger financial commitments we are having to take. Please read the cancellation section in the FAQ before signing up.

Course Information

The course runs around the Samphire Hoe nature reserve and then along the sea wall in 3.71 mile loop and out and backs. The trail is very high quality, there is one little hill near the sea wall and another not too far from the start of each loop. The sea wall is concrete and flat.

8 loops of 3.71 miles will be an Ultra by 100 Marathon Club standards.

The 100 mile distance is 27 x 3.71 miles loops = 100.16 miles.

You can view the route on MapMyRun here

The total elevation gain is about 100' per loop, about 2500' for the 100 miles.

Marathon Distance

7 Laps is 25.97 miles which is cruelly close to a marathon but not quite and we do appreciate that some folk coming along for the timed challenges won't necessarily want to do a 29.68 mile ultra. So if you "just" want to do a marathon after 7 laps pick up a flag and go out on a short lap, this short lap is out as normal but turning right after the "zig zag" section. You'll be credited with a 26.5 mile marathon finish in the results. This will not be signed on the course to avoid the risk of confusion and this short lap option obviously only available after 7 laps and once taken you'll have to ring out afterwards.

Where do I park?
100 mile runners/24 hour challenge runners please park following the blue arrows. 12 hour/6 hour runners supporters and crews please park following the red arrows. Please only park in the main car park if the other areas are full. The car park and toilets opens at 0700. Samphire Hoe, A20 Folkestone to Dover road, CT17 9FL (Map). There is a charge of £2 per day for parking. For entrants to the 24 hour or 100 mile event we'll have printed parking permits available for £5 to cover the entire duration of your stay, cash only and these must be displayed in the windscreen of your car. 100% of this is donated to the Samphire Hoe Nature Reserve.

When do I get my race number?
You'll pick this up on race day morning from the race base camp.

Are there time limits?

For all events the absolute cut off is 1600 on Sunday. It's a hard cut off. Nothing counts after this.

For the 6/24 Hour Challenges you must be inside your last loop at 6/24 hours after you started (subject to the absolute 1600 Sunday cut off) even if you finish your final loop after the respective time limits, any laps after the time limit won't count. i.e. if you start a six hour challenge on Saturday you can start an extra lap up to 5:59:59 after you started.

Any runner completing 7 laps + a mini lap will have completed an official marathon (by 100 Marathon Club standards.), 8 laps is an official ultra finish. As long as you finish one lap then you'll receive an official finish time, medal and goody bag. With timed events there are no DNFs.

A DNF will occur at the 100 mile event if you started a loop after 0800 on the Sunday and subsequently fail to finish or are timed out which then unfortunately counts for nothing. So for 100 mile runners if you start a lap after 0800 on the Sunday you are deemed to be continuing in the 100 mile event and the option to drop down to the 24 hour event has gone, if you then subsequently withdraw or are timed out then that's a DNF. Before that point you can drop down to the 24 hour event and receive an official finish.

How do the 6/24/Pacer hour Challenges work?
These are three separate events.
The 24 Hour Challenge starts at 0800 on the Saturday with the 100 Mile starters
The Saturday 6 Hour Challenge starts at 1000 on the Saturday.
The Pacer Challenge start time is flexible and you can start at any point after 1800 on the Saturday, (Please bear in mind that you cannot access the site after 1830 at night until 0700 in the morning. You can drive out, but not in.)

Unofficial pacing isn't permitted with the exception of crew/supports are welcome to join 100 mile finishers on their final lap.

This event will be set up so that having a crew won't be necessary however if runners wish to have a crew/supporters then of course then can. However crew/supporters aren't allowed to hang out in the aid station/base camp area simply as there won't be the space. This is for runners and race event people only. Crewing will only be allowed in the green zone.

What are the toilet facilities?
There are male and female toilets in the circular structure you can see in the photo above, it's just a few steps off the racing line and we'll have additional portable toilets in the crewing area.

No camping, tents, gazebos etc are allowed on site. Nor will there be any sleeping facilities at the start/finish/base camp area. Though you're always welcome to catch forty winks in your car if you wish to.

What time is Sunrise? Moonrise?
Sun rise is 0645, Sun set is 18:46

Moonrise is 2055, Moonset is 1235 and a week off a full moon so if clear will light things up nicely.

How are laps counted?
At race registration you'll be handed a small laminated lap counting card, attach this to yourself with a safety pin or cable tie. At the end of each loop get this punched through by one of the hole puncher chaps or chappesses. So basically at the end of each lap, get your card punched, or ring the bell! We'll swap cards over as the event goes along rather than just one giant card!

Do you have secure baggage facilities
No. But you're free to leave bags at the start/finish. There will always be someone around but we can't guarantee their security. You'll be able to park close to the start/finish don't forget.

Can I leave my own drinks/food at the aid station?
Yes no problem at all, we have a dedicated table for runners own supplies if they have anything special that they'd like to bring along..

Trail shoes? Road Shoes?
Road shoes should be fine. Its 99% on perfect surfaces, you might have a couple of pebbles to step around, but otherwise all on sealed tarmac/concrete/gravel and a couple of wooden bridges. Gaitors would be wise.

About 75% of the trail is like this... and there is the main hill. The rest is pretty decent too.

The sea wall is like this, it has a marginal camber to throw sea water back in to the sea but its not much. It's quite grey and dull, but you can see France on a clear day and quite a few ships, on a murky day you can see, well, murk.

Is the course closed to the public?
No. We are on a public nature reserve. Runners do not have the right of way and need to be considerate of other users of the land, there may be fisherman on the sea wall part and dog walkers, ramblers or cyclists on any part of the course. Please don't litter. We'll have a bin at the base camp, please use this and there are several bins on the route too.

What will base camp be like?
We're hiring the education centre for the weekend. This will be used for registration, the aid station and for supporting runners in general.

What on course facilities do you provide?
Water, squash, nibbles, starter, timekeeper and encouragement every lap! Base station will be well stocked for all runners. We will feature more "ultra" centric food than usual. To minimise waste we will not be providing bottles of water, just cups and unlimited water to fill bottles or bladders.

Are there any facilities at the start/finish area?
Yes there are toilets (open from 07:00 Saturday) by the car park near the start/finish. There is also some information about the reserve and a small cafe.

What about hot food?
There is a cafe in the start/finish/base camp area where drinks and snacks can be purchased (they do awesome bacon baps!) and we've agreed with the venue that whilst this is open that we'll not offer any hot food or drink offerings. Outside of these hours we'll have tea/coffee/hot chocolate and simple hot things such as noodles for folk who'd like something warm in the night or early hours.

Can I use an ipod or mp3 player on the course?
Yes. Though please be aware that you are running on public footpaths with the general public so make sure that you pay attention to traffic, people, children on bikes, wildlife and so on.

Public Transport?
The nearest train station is Dover Priory and that's 2.7 miles away.

Cancellation Conditions.
This event falls outside our usual "Fair Runners Policy"

Withdraw prior to 1st March and we'll credit you with three "race credits" for alternative SVN Events.(i.e. our regular six hour challenge/marathons)

Withdraw prior to 1st June and we'll credit you with two "race credits" for alternative regular SVN Events.

Withdraw prior to 1st September and we'll credit you with one "race credit" for an alternative regular SVN Event.

Outside of these limits unfortunately the place will be lost.

Why is the event expensive?
Firstly we're making a big financial investment in the event, we're committing to a donation to the venue for the use of it in the thousands rather than the hundreds. Secondly we're going to have kick ass buckles, medals and shirts. We're only going to have limited numbers of runners and we don't have the economies of scale we'd like to be able to get this low cost. Running 100 miles is awesome, you deserve top notch stuff. When you finish that 100 miles you'll be glad of it.

Can you point me to some advice about running 100 miles?
