Fractured Marathon Cover Image 2021.png

          5pm, Saturday 30th October 2021          


The Fractured Marathon is an exciting event for teams or solo runners of all abilities. The innovative format was a smash hit with participants at the inaugural event in 2019. It created a great atmosphere and was as much a Friday night running party as a race!

Based in the grounds of the spectacular Calke Abbey, the event will run for 5 hours from 5pm until 10pm; going from sunlight to starlight.

There will be 10 timed laps around a scenic 2.6-mile course, which will start every half hour on the half hour.

Teams, or solo runners, can take part in as many or as few of the 10 laps as they like. For runners, solo and team, to be eligible to run the next lap they must be back before it starts. Otherwise they will have to wait for the next start time to re-join the game. So, to remain in with chance of completing a full marathon, each loop must be completed within half an hour.

Categories and Prizes


Teams can be entered in the following categories:

  • Male

  • Female

  • Mixed (at least 50% of loops must be run by a female runner)



There will be prizes for the fastest accumulative marathons for teams in each category and solo runners.


Plus there are opportunities for individuals to achieve distance personal bests in a fun way (e.g. run your first half marathon, full marathon or other distance), or for team / club-mates to have a competition amongst themselves.

Frequently Asked Questions

  • Background
    2024 will be the fifth edition of our Peak District Ultras. Creating an iconic ultramarathon for the Peak District is something that Peak Running founders, Andy Brooks (Brooksie) and Chris Hopkinson, had been thinking about for many years before. As a fell and trail runner since the mid 90's, Brooksie has always had a penchant for going long. So, while there have been some great races in the Peaks over the years, satisfying that desire has traditionally meant travelling a long way from his Derbyshire home. To take on his first 100-miler, he had to go all the way to the mountains of Virgina, because there was yet to be one in the UK in those days! Chris' passion for mountain marathons in remote locations, and the challenge of planning routes through the terrain, is something that has seen him travel to other parts of the UK, and overseas (including Iceland and Japan) over the years, to enjoy his fix too. The increase in popularity of mountain and ultra-running in the UK in more recent times has led to some fantastic events emerging in the other national parks. Something that the guys have revelled in. But their own backyard, the Peak District, was still crying out for something special in their view. Our aim, therefore, with The Peak District Ultras is to provide an event that's not only a fantastic experience for those taking part, but something that is also a special day for the communities within our favourite playground, the 'original' national park. In our view, the Peak District is the best place on the planet to go for a run. Click HERE to to understand why.
  • Race Ethos
    Our ethos for the event is aligned with our ethos for Peak Running as a whole. We want it to be an event that is capable of challenging even the most experienced ultra-runners, while also inspiring those within the wider running community to push their boundaries and achieve things they may not have thought possible themselves. So, in addition to the race itself, there is bags of guidance and support available to help you achieve your ambitions and complete the event safely. We want there to be some tough competition at the front of the fields in each distance. But we also recognise that, for the majority, simply finishing is winning for them. So even if you're not a fast runner, or you'd prefer to hike, it's designed to accommodate you. From a broader perspective, we want to make it an event that has a positive impact on the Peak District, its communities and the local environment. An event that residents, local businesses, and those that look after the delicate landscapes within the park, support and look foward to. Our commitments to this fundamental aim for the event include: Donating a proportion of the profits to the Peak District National Park Foundation charity to help them protect this wonderful park, for everyone, forever. Building strong relationships with the park authorities and land managers, their rangers and other stakeholders. Organising conservation days for runners to help carry out important conservation and restoration work on the trails within the park. Using the event as a vehicle to help promote and educate people on the work and behaviours necessary to maintain the beauty of the park for future generations. Using community facilities for event HQ and checkpoints wherever possible. Using local independant buinesses for supplies, such as race mementos, t-shirts etc. Ensuring there will be no trace of the event by the time it is wrapped up on the Sunday.
