Welcome and Hello

If there is one thing that Bys Vyken Events does, it brings you iconic races!

Its a very warm welcome back to the classic and ultra Jack

Races that will test you but leave you wanting more 

These races run along the most imposing part of the Cornish coastline but with

awe inspiring beauty

This race has it all. Climbs, mud, bogs, rocks, boulders, tarmac, sand, water and more hills. Believe it or not

sometimes snow and even a heatwave!

There are the 2 races to chose from Classic or Ultra

The classic is an 18 mile race from St Just to St Ives

The Ultra starts and finishes at St Ives with Cape Cornwall as your turnaround

The classic starts at 10 am with a 7 hour cut off (safety, 5 hour cut off at Zennor Head)

The Ultra starts at 6.30am with a 12 hour cut off (safety cut off at the Cape and Zennor)

Cape 7 hours

Zennor 10  hours


Both races are self navigation race but there will be marshals at key points to help guide you. There will

also be some arrows to keep you going in the right direction. We will be using sawdust  to mark the trails.

There will be 3 aid stations, due to the remoteness of the route

Pendeen Lighthouse   Food/water stop

Gurnards Head    Food/water stop

Zennor Head    water only

Ultra   you have these stops on the way out and back but you also have

a turnaround food/water stop at Cape Cornwall

The Jack is a challenging event but runners come back year after year, myself included!

The cut off times have been slightly extended to give more people the chance to 

experience the raw beauty of this race

Thank you to all the businesses that support us and all the volunteers. These events would never

happen without you

Health and Safety

We do our absolute best to make sure your day goes swimmingly but sometimes things go wrong.

If you are unwell, please do not turn up and try to run. The whole thing could unravel very quickly.

Look after yourself and your well being first

In light of new government safety guidelines, please pay extra care attention when on the coast path or near large bodies of water. If you are unsure or feel unsafe, please make a marshal aware and we will get you to safety.

Please dress appropriately for the weather, this is an Winter race and  Cornish weather can change instantly.

Some parts of this course are very remote and therefore the kit list is mandatory

The kit list for this event is built on years of knowledge. We would not run without it


There will be no entries on the day and you will be asked for ID.

For safety and medical reasons, we must make sure nobody is running under someone else's name. It is foolhardy and dangerous

Please fill out all the details on the back of your bib number. This is in case you get into difficulties.

It also has our emergency contact numbers on it

We have Omega Medical attending the event and looking after all the runners. They have been at every Bys Vyken event since 2016 and are thoroughly experienced. We would not trust anyone else

If at any point, you feel the need to retire from the event. Please get word to a marshal or contact us directly. We need to know that you are safe. You must return to HQ as we need the timer chip back please

Please respect the environment and do not litter, deliberate acts of littering will be a disqualification

Please overtake runners responsibly and also give way to other runners safely. Respect everyone 

The event is timed with ankle tags, so please think where you would like to be at the start line. May not be worth getting trampled on by the stampede.

For your safety, we have cut offs. These will be stringently stuck too especially at Zennor. Think long and hard 

about continuing if you are within 1 minute of the cut off. On a good day, its at least 1 1/2 hours to St Ives.

Cut offs are there to make sure everyone can complete these events safely. We will have marshals out there all that time and sometimes the weather can be extremely demanding  

Other things to remember

 You will be passing each other on narrow paths. You are asked to respect each others distance and space when passing where you can. This includes the tourists and walkers you will encounter on the coast path.

Sorry, no dogs are allowed to run in this event

All ID shown must be a physical item, ie; drivers licence, passport

All aid stations provide your standard fare for a race day, crisps, nuts, sweets and fruit. There are large water containers at each station as well as cola. Bys Vyken are a cup less events company so please bring your own.

Please also be respectful at The SurfHouse and at The Miners Chapel. They have allowed us to host our first event here and we would like to come back again next year

This next bit is very important.

We don't make these kit lists up for a jolly. If you get into difficulty on the course. This could very well save your life. 

We very highly recommend that you put What3words app on your phone as well
