Clennell Colossus

A 25/50 Mile XC MTB Challenge

Sat 10th June 2017 : Long route £29, Short route £25.  Entries open late 2016 

The 2016 long route was just about as hard as it could possibly be and riders pushed themselves to the limit to get round.  You’ll be happy to know that things are toned down for 2017 with access being opened once more to the original route options.   Once again we will have two distances on offer: 25 miles and 50 miles.  Don’t for a second think the shorter route is going to be easy, it skips straight to the big stuff and you’ll be faced with the same 3 final climbs as 2015 including the famous Trows to Windy Gyle section.  We can’t wait to welcome all you bikers back to area!

The big change for 2017 is the day has been switched to Saturday instead of Sunday.  The only real reason for doing this is so we can all have a knees up afterwards in the bar.  Only being honest!  There’s camping on offer just outside the hotel and you can stay Friday, Saturday and Sunday if you wish.  Or why not use the event as a reason to visit Northumberland and the National Park with all the surrounding attractions.

Want to go far and get high?  Northumberland National Park has some of the best natural mountain bike trails around with unrestricted off-road access for mile after mile as you climb uphill with burning muscles and tackle rapid downhill sections.  We’ve worked hand in hand with land owners, Northumberland National Park, Forestry Commission, British Cycling, MOD and many more to bring you this event.  This course will offer you a unique challenge as you try to get yourself round the ever undulating hills of the area.  This is not the Lake District or the west coast of Scotland but don’t be fooled… there are some big hills in these here parts!

What’s the idea here though?  This is not a race.  You can go as fast or as slow as you like, the choice is yours.  The Clennell Colossus is a challenge event and you test yourself against the course and the environment.  Our concern is that you get to see for yourself how beautiful the area is, that you do it safely and that you have FUN!  We’ll provide food and drinks on the way round and our team will check you all reach the checkpoints or we’ll come out looking for you.

You can turn up for the event and do the whole thing and then go home again, that is no problem at all.  We will sort out the free parking for you on the event grounds.  One of our general aims is to promote the area and the outdoors so we have free camping for the weekend on the site grounds.  In fact the only thing we ask is that you let us know in advance if you want to camp.  There is also the option of staying in Clennell Hall Country House itself or any of the other local B&B spots.  For more info on accommodation please click here.

The route will be fully marked. Marshals will line the way.  GPS files of the exact route will be sent out with the info pack.


There will be multiple checkpoints along the way.  Here you will find water and food to keep you going.

Medical Info

If you have any medical conditions you must tell us in advance of the ride.  A professional medical team will be on site to deal with major incidents.  First aiders can also be found around the course.  Each rider will be given essential safety info to take round with them that has key details on it.  Mountain Rescue are informed of the event.  The nearest hospital is Cramlington Accident and Emergency Hospital.

Mandatory Kit List

This is the Cheviots and although you do get still, sunny winter days you need to be experienced in and prepared for bad conditions.  Even in June this can mean high winds, hail stone and cold temperatures.  The ride won’t be called off due to bad weather (lightning apart) so you’ll just have to deal with it.  Here’s your list:

  • Enough fluid for 2 hours of riding
  • Emergency whistle
  • Waterproof/Windproof jacket/gillet (can be one jacket)
  • Hat and gloves
  • Leg cover either in the form of running tights or waterproof covers.
  • Emergency survival bag – the plastic kind are just find and cheap as chips.
  • Food of your choice.
  • Mobile phone.  It will only work when high up but it can be a vital lifeline in an emergency.
  • OS Map OL16 1:25,000
  • Helmet and lights

This kit will be checked before the run starts as no chances will be taken out on the hill.


Maps and gps files will be released before the day.


Got something on your mind?  We might be able to help you here:

Do I need to register in advance?

Yes.  All participants must enter in advance using the online booking.  For registration info please see above.

Will we receive a map of the route?

You will be sent the map as part of the information pack around 1 week prior to the event.  There will be a map of the route on display in the registration area.  The route will be well marked but in the event of any issue refer to your map.  The route is well sign posted with marshals at key points.  A gps file will also be made available in the info pack.

Are there Age Limits for Participants?

Yes.  All runners must be 18 or over.

Should I bring my family?

Why not.  There is free camping on offer for as many people as you care to bring.  They can walk around Clennell or sit in the cafe in the event of bad weather.  If people want to see you on the course then they can drive round to the Coquet valley and you passing there.

Can I bring my dog?

You can bring your bog to the event but not out onto the hills when you’re riding.

What bike should I bring?

Any off road bike will get round including mtb, fat bikes, cyclocross etc.  It’s been said the ideal candidate would be a short travel full sus bike.

Can we stay the night before?

There’s free camping on offer but please let us know if you’re taking this up.  There are also a number of local B&B’s, particularly in Rothbury.

Do I need a support team?

No.  We will man the event and make sure you get round OK.  You will need to bring essentials such as a kit list/compulsory items mentioned above.

What happens if I drop out?

We encourage anyone to try as hard as they can but there is no point in going beyond your limits.  Injury, fitness or even a family emergency may mean you have to leave the event.  If this happens on the course please go to the nearest checkpoint and let them know you are dropping out.  If you only go to one checkpoint please try and make it the registration area as this is the final count of who has finished and left the area.  If you don’t then we’ll presume you are missing and go on a man hunt!  Always sign out of the event.
