Mendip Murmuration

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’ festival.  

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 20 or 30/35 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.

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! 

Camping Ticket:  Come for the whole weekend (staying over on Friday night and/or Saturday night in a tent or campervan) and enjoy everything the Top of the Gorge Festival has to offer, including all entertainment (guest speakers and live music) and on-site activities, such as guided food foraging, themed walks, yoga, star-gazing, climbing, caving, slacklining and even archery and axe throwing. The event is fully family friendly, with adventures suitable for a range of age groups. Registered riders save 25% on the price of a weekend camping via a discount code which will be emailed to you when you enter the events. You can book your camping via the festival website.

Rider Ticket: Sign up to the mountain-bike event, and enjoy a free day ticket as part of your race entry (worth £20!) Your race number, handed out on the day of the event, will act as your festival ticket. You can enjoy all parts of the festival; caterers, music, free inspirational talks and free activities.

Spectator Ticket: Many parts of the festival are free to access for people who are there to support riders during the day (until 5pm); there is a wide range of caterers, live music, the race start/finish and of course the toilet, water and first-aid facilities. To help cover the running costs of the festival, there is a suggested £5 donation per adult in the form of raffle tickets. There is no suggested donation for children, though the more tickets you get, the greater the chance of winning – and the first prize of the raffle is £10,000. The Spectator Ticket does not include access to the free activities and entertainment that comes with the camping or day tickets, for example the talks by international adventurers, climbing wall and caving experience, story telling, guided walks, archery and axe throwing etc – and you must be off site by 5pm. If you wish to enjoy this elements of the festival, you are welcome to pay as you go, or to upgrade your ticket to a Day Ticket at the festival ticket office. It’s not possible to purchase spectator tickets in advance of the event.

Parking is free for riders and spectators however, spectators will need to buy festival day entry or event spectator entry should they wish to access the event village. Marshals and signage will direct you to the parking area.

There is a main loop not exceeding 20 miles. All riders will head out on the first 20 miles. Those who make it back before the second loop cut-off time can choose to continue onto the second loop. This is an extra 10 – 15 miles. 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 2020. In this e-mail will be links to the GPX files that you can download to your device for each of the loops if you so wish. We advise that you transfer the route onto your 1:25000 maps of the area.

Why not make the most of the weekend by spending it on the Mendip Hills and entering into the festival atmosphere. Full weekend ‘Top of the Gorge’ festival tickets are on sale from the National Trust website. Full details and a link to the festival bookings portal to follow soon.

Riders briefing in front of the main stage at 09:50. All entrants to be present.

In the event village you will find:

  • The registration tent, which will be open from 08:00
  • Before and after the ride refreshments will be available from a range of caterers in the food area of the festival.  This is not included in your entry fee
  • Merchandise tent. Collect your pre-ordered t-shirt or hoody from here
  • More to be confirmed when festival tickets go on sale

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 main loop 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.

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. Those planning to complete the extra loop need to be happy riding 30-35 miles and able to complete the first 20 miles within 3.5 hours.

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.
