Jayne Lloyd has organised Marathon Eryri since 2004. Since then the race has grown from a 600 runner event, to today’s 3000 capacity marathon, and now is amongst the UK’s most iconic marathons. 2025 will be the 41st edition of the event and see Jayne organise her 21st race!

​

As a former international mountain runner, Jayne knows what it takes to complete such a challenge, and what the runner wants on that journey. Her enthusiasm and knowledge come through in all that the race offers and is a big attraction of the event.

​

In addition to Jayne there is a core organising and media team.

​

Anthony & Mari Rogers, Dyfed & Rhian Whiteside-Thomas, Matt Ward, Hannah Hughes and Barry Davies are instrumental in aiding Jayne co-ordinate the race each year. Event logistics, course management, registration and marshal organisation, volunteer co-ordination, race media and communications, along with social and TV media work all fall under the remit of this close-knit team.

​

The Llanberis community are also an integral part of the event. Whether it is lugging a barrier on race day, organising marshals, informing the local village of what is going on or standing out for hours in the rain on race day directing traffic and runners, they are always there!
