Join us for a special Gathering and film night as we celebrate the return of the Pan Celtic Race Series in 2026.
A Call to Gather ~ London Calling
2026 saw the return of The Pan Celtic Race with the start of Chapter 2. A new series of races culminating in a Year 5 adventure to equal the Magnum Opus.
On October 3rd, the team behind the event will be premiering the latest film – “The Flight of the Druids” in Central London. It will be a Gathering unlike any before, with an organised ride taking in the sights and sounds of the capital and beyond, before returning to our venue for the evening – The Greenhouse Centre right in the heart of Marylebone.
A breathtaking Grade II listed building designed by the renowned architect Thomas Hardwick and built between 1822 and 1824. It stands as a towering example of early 19th-century Neo-Classical and Gothic design and we have it for the weekend.
In usual Pan Celtic Gathering style, we will meet up Saturday morning, get out for the day on our bikes before returning to the Greenhouse Centre. Here you can shower, freshen up and grab some food. There will be pizza, beers and then the reason we are all going – the world premiere of our latest film.
A film by Jordi Garcia, The Flight of the Druids follows our intrepid Clan of Riders as they embark on a modern retelling of an ancient Celtic story.
Beginning beneath the castle walls of Conwy, the route follows the flight of the Druids from Wales towards sanctuary in Ireland, escaping the advancing forces of Rome and carrying with them their knowledge, traditions and beliefs.
What follows is a journey through some of the wildest landscapes the Pan Celtic has encountered, but, as ever, the film is really about the people who chose to ride it.
Their reasons for being there. The friendships. The suffering. The occasional questionable decision. And the stories that unfold when inclusivity doesn't stop at gender, colour or religion, but means finding a way for good people to take part when life has put something in their way.
A true #ultraforall
After a year away, the Pan Celtic is back.
This is Chapter 2.
And for those already wondering about 2027, everyone joining us in London will get early access to entries for both the 2027 Pan Celtic Ultra and Gravel Rally, a full week before they go on general release. We'll also be giving you the first look at the new Ultra routes on the night.
----------------------------------------
THE PRACTICAL STUFF
Doors will be open from 10am on Saturday 3rd October, with the ride heading out at 10:30am. There'll be secure space at the Greenhouse Centre to leave bags and kit while we're out, and we'll aim to be back at around 6pm.
Showers are available at the venue, so there'll be time to get yourself vaguely respectable before the evening begins.
We'll get pizzas in and there'll be beer, soft drinks and the usual bits and pieces available through an honesty bar, all at cost. There are also supermarkets nearby and you're completely free to bring or order your own food if pizza isn't going to cut it.
The world premiere of The Flight of the Druids starts at 8pm, followed by a Q&A with the team and those involved in making the film.
Tickets for the event are just £5, helping us cover the costs of the evening, with a donation also going to Greenhouse Sports charity.
And, rather conveniently, nobody actually has to leave.
For another £10, you can stay overnight at the Greenhouse Centre. This is very much Pan Celtic accommodation rather than The Ritz – bring a sleeping bag and sleeping mat and find yourself a suitable patch of floor for the night.
We'll provide the roof. You provide the bed.
Then, at some point on Sunday morning, we'll quietly return Marylebone to its rightful owners.
OUR PARTNERS
The Pan Celtic wouldn't be what it is without the people and companies who continue to get behind what we do.
A big thank you to Curve Cycling, Albion, Restrap, Exposure Lights, Styrkr, Wildhorse Brewery and Scribe Cycling for continuing to support the Pan Celtic and helping us make these adventures happen.
This is a social group ride, but you’ll need to be self-sufficient. Bring what you need, be comfortable with basic repairs, and come prepared for a full day out.
Lights for visibility and helmets are mandatory.
Ride sensibly. We’re out on open roads, so respect other road users and look out for each other.
And that’s it. Turn up, ride your bike, and spend some time with the Clan
