One legendary trail, one breathtaking 100 mile adventure
Welcome to the Sirona 100
Save the date – August 23rd 2025
Join us for an adventure on the Wales Coast Path
The Sirona 100 takes place on one glorious trail. The indomitable Wales Coast Path, a world’s first when it was officially opened in 2012, as a continuous foot path stretching around the entire length of the country’s coast line.
The route will follow the Wales Coast Path sections bordering Snowdonia National Park and the Ceredigion Coast path.
With probably the most varied landscape and terrain of the entire 870 mile coast path, the route is flanked by the sea to the west and the mountains to the east. With a wealth of wildlife, geological and archaeological features there is a colourful history to discover along the way.

Checkpoints
There are 8 checkpoints in total and 1 finish line (understatement of the year). You will never have to travel too far without seeing some of the most incredible volunteers out there (they truly do rock). Our checkpoints will be fully loaded with excellent food options, gallons of delicious drinks and wholehearted volunteers that will go above and beyond to help you on your adventure. All food allergies can be and will be catered for – as long as you let you know before the event (sadly we aren’t mind readers).
Cut offs
At Sirona, we are all about the adventure and we really don’t want you stressing too much about cut off times. You will have a total time of 50 hours to get across that finish line. That is genuinely a lot of time. It’s an average of 2 miles per hour and we know if you are signing up to tackle a 100 miler then you have it within you to average at least 30 minutes per mile.
Drop bags
Drop bags ARE recommended and are NOT compulsory. Each runner is entitled to 1 x drop bag and it must NOT exceed 45 cm x 75.5 cm x 45 cm, with a maximum volume of 132 litres in size. Your drop bag will be available to you at three aid stations along the route. Please note all drop bags will be returned to the finish line in time for your finish. Plastic boxes or suitcases will not be allowed.
The Course
This incredible 100 mile adventure is very much achievable with the right training and approach. The route itself may seem a little daunting with 15,000ft of elevation gain but the course itself is very much runnable in sections and let’s be honest we all walk at some point during a 100 miler. It just means you can take in some of the most breathtaking views Wales has to offer. The beautiful mix of the sea to your west and the mountains to the east come together to deliver a whistle stop tour full of highlights that will live long in the memory and in the legs.
The Sirona 100 will be a mental and physical rollercoaster at times, mother natures rollercoaster with an accumulative elevation gain of 15,000ft over the 100 miles – this course packs a punch but also a big cwtch. There are plenty of runnable sections with lots of downhill for those who love cutting loose.
What to expect once you sign up?
A friendly confirmation email will be sent to the email address you registered with.
The next time you will hear from us (directly) will be in the form of an email 8 weeks before the event, then another email 4 weeks before the event and a final email 2 weeks before the event.
Alas that isn’t the last communication – please keep an eye on your mobile for a phone call from our Race Director a couple of days before the event is due to take place – don’t worry you haven’t done anything wrong, it’s a peace of mind call to make sure you’re ready for the big day!
We’re not promising you an easy run. My goodness there is a total elevation gain of 15,000ft. But please know – this is very much an achievable challenge with the right training and game plan on the day(s).
Sirona will help you reach your wildest dreams when it comes to running a 100 miler.
