Mendip Murmuration


After a COVID-driven cancellation in 2020, we’re delighted to say that the Mendip Murmuration will be taking place this year on Saturday 12th June 2021. 


The Mendip Murmuration is a gathering of like minded individuals coming together with a common purpose. Riding your bike through some of Somerset’s stunning landscapes. Cruising and carving over and around Cheddar Gorge, Crook Peak, Black Down and Rowberrow Warren will make for an amazing 26.5 mile route that will leave you wanting more. Limestone rock gardens, flowing single tracks, wide open hill top trails with stunning views and cracking forest trails show you the best the Mendips has to offer. 


The Mendip Murmuration is now firmly cemented as one of our three Somerset based off-road cycling events now known as “The Triple’. Over the last four years we have developed a fantastic working relationship with The National Trust and The Mendip Hills AONB service to make this great mountain biking event part of the


‘Top of the Gorge’ Activity Weekend’. 


Inevitably, given the ongoing coronavirus situation in 2021, the National Trust cannot host a full-blown Festival as they would like to and as they have done in previous years, however plans are underway instead for a real celebration of outdoor activity in the Mendips as part of an organised Activity Weekend. 

A variety of running and cycling challenges are already part of the plan with more activity options to follow, and our collective aim is to offer people a range of fun and enjoyable events – which obviously includes the Mendip Murmuration. 

So get your entry in NOW for your chance to enjoy a fantastic 20 or 30/35 mile mountain biking experience exploring the stunning Mendip Hills AONB!

Starting & finishing at:

The Top of the Gorge Activity Weekend Site

Warren Farm, Charterhouse, Blagdon, Bristol BS40 7XR

Places are strictly limited to 300 – Enter now to avoid disappointment or alternatively enter The Triple’ to guarantee your place in all three mountain biking events. Triple entry opens soon!

Saturday 12th June 2021


Top of the Gorge Festival, Warren Farm, Charterhouse, Cheddar 


  • Registration opens: 08.45
  • Ride briefing: Via video and/or email 2 days before.
  • Ride Starts: 08:45 – 10:00 

There is one distance available for 2021, 26.5 Miles. We are very aware that this isn’t our usual style but we have made a decision to make all three events in the Triple Series for 2021 single loops of around 25 miles. 

Due to the current situation we still have many landowners who are very nervous about events and gaining the appropriate permissions is proving difficult. Public rights of way do not have the same public access for organised events and land owner permission needs to be sought. We are also working closely with Natural England to develop a route that minimises the impact on the sensitive landscapes we use.  To give you the best experience we have decided to concentrate on putting together 25 (ish) really good miles of fun on the Mendip Hills, Exmoor and the Quantock Hills. Each event will still have the ‘Miles Tea Stop’ at roughly half way to keep you fuelled and ready to pedal more miles.


£37.50 per rider. All under 18’s must be accompanied by a supervising rider over the age of 18.

Entering the Murmuration, Explorer or Quake? Continuing for 2020, why not be part of the elite who complete ‘The Triple’! Find out more about ‘The Triple’ here.


Registration opens at 08:45. Please bring with you a completed personal details form for each person in your group. This can be downloaded from the downloads page or by clicking here.


Parking is free for riders and spectators. Marshals and signage will direct you to the parking area.


Some of the route is over the sensitive area known as Blackdown, to get an event over this section has been very difficult, please ensure you stick to the way-marked route and don’t cut corners. A copy of the route will be e-mailed out on the 10th June 2021. In this e-mail will be links to the GPX files that you can download to your device if you so wish. We advise that you transfer the route onto your 1:25000 maps of the area.


With no wider festival this year, camping onsite is unfortunately not an option. There are however plenty of local campsites and accommodation providers who would love your support. 


Via video and/or email 2 days before.

In the event village you will find:

  • The registration tent, which will be open from 08:45
  • Before and after the ride refreshments will be available from a range of caterers in the food area.  This is not included in your entry fee.

There are toilets on site.

At registration you will be given a number board which must be attached to your handlebars. Riders must stop and have their number recorded by the marshals at each check point. As part of our duty of care these rider numbers are radioed back to the control centre to record your progress. Your rider number must also be submitted to the registration desk upon your return. This is how we know you are safe and accounted for.  Avon and Somerset Search and Rescue will be present should they be required.

There will be regular checkpoints on both loops. Many of these will have water and sweets to keep you going. The half way checkpoint on the main loop hosts the famous ‘Miles Tea Stop’. Grab a brew and some amazing cake before continuing on!

On arrival at our halfway checkpoint you will be greeted with a smile, treats and a nice brew courtesy of our friends at 
Miles Tea.

Please bring lots of fluids. We ask that you come prepared and self-sufficient for a long day out in remote moorland. We will be providing water at most checkpoints should you run out. We are more than happy to top up your water bottles but will not be supplying cups in an attempt to make the event more environmentally friendly. 

I’m afraid that at this event dogs are not allowed to compete. They are very welcome to join the spectators though as long as they are kept under close control. Spectators will need to buy festival day entry should they wish to be granted access to the main event site.

Provided by the first aid crew employed by the festival organisers with support from the Channel Events team.

Our events are challenge based but with the aim of the main loop being accessible to all. We do recommend that you get some miles in on off-road terrain beforehand. 

You will need to provide your own bike and safety equipment. We recommend you take the following kit list with you during the event. This is however up to your discretion and you take or leave the following items at your own risk.

  • First aid kit for the treatment of strains, sprains, blisters and gravel rash
  • Food and drink as required, including emergency food
  • Compass
  • Ordnance Survey maps of the area
  • A whistle
  • Multi-tool / puncture repair kit / spare tubes / pump
  • All entrants must take account of the weather conditions which may be encountered during the ride. You may deem it necessary to carry additional items such as; more layers, torch & batteries, waterproofs, survival bag, mobile phone

Warm weather can pose just as many problems as bad weather. Whatever the weather conditions please make sure you are appropriately equipped to deal with a long day, in a remote environment. The event will run in conditions deemed safe by the event organisers. Should the conditions not be appropriate the events team will contact you no fewer than 12 hours prior to the event registration. See terms and conditions for our cancellation policy.

Celebration is the key! Lets see those arms aloft as you cross the finish line. Then move onto the registration desk to submit your tally number and receive your branded event souvenir and completion certificate. Please make sure that you submit your rider number tally; this is a requirement as part of our duty of care. 

We will have a professional photographer on site so smile when you spot them. 


Not only do you get to challenge yourself in this truly stunning environment, you get day access to the ‘Top of the Gorge Festival’. You get to share your experience with others while Channel Events takes care of the safety of your day and provide a stunning route (and a brew). Included in your entry is a Certificate of completion, Completion Souvenir, day pass to the Saturday at the Festival, friendly marshals, locally blended tea and roasted coffee from Miles, checkpoints with water stations, and a fabulous day.

Can I hire a bike?

We don’t offer this service through Channel Events. We suggest that you contact the local bike shops who may have a fleet of hire bikes or a demo bike you could use.

Can I get water and snacks along the route?

We ask that you are self sufficient for the distance you are intending to ride but there will be water and sweets available at many of checkpoints should you run out. The half way checkpoint on the main loop will also accommodate the ‘Miles’ tea stop. Here you can treat yourself to a brew from our favourite local tea and coffee blenders.     

What if I run out of time?

All riders will complete the main 20 mile loop. This can take you until 4pm if required. If you are hoping to do the extra loop then there is a cut off time of 1:30pm. This gives you 3.5 hours to complete the main loop. Riders arriving back from the main loop after 1pm will not be permitted to continue.

I’m under 18, can I ride on my own?

No, we ask that any entrants under the age of 18 ride with an adult on a ratio of 1:3.

What is the Triple?

Check out The Triple webpage for full information. 


Is it possible to get lost?

The route will be well way-marked and seperate colours used for each loop. Blue for the main loop and red for the extra loop. Major hazards and awkward junctions will be marked with black/yellow signage. We also ask that you carry an Ordnance survey map of the local area and transfer the route onto this prior to the event. Riding with your head down and not paying attention could result in you going off course. With this in mind we suggest that you follow the route way-markers with care.
