Cwmdu West is the region towards Mynydd Langors from Cwmdu. 

This 1.5hr Maprun is a good intro to the MapRun app. The terrain and location of checkpoints will suit beginners. 

MaprunF. What is it?
Maprun is a free 'app' you download to your phone. It automatically records which checkpoints you visit, when you start and when you finish. After, your score and route is uploaded automatically to the overall results table. 
When you find a checkpoint, your phone emits a loud bleep, the point on the map changes from pink to green and your time to get there is recorded automatically.
Don't panic all you technophobes! It's very intuitive to use and once started you can if you like just stow your phone in a pocket or bumbag.

Score event. What does this mean?
There is no prescribed route. You visit any of the checkpoints in any order.
On this MapRun each checkpoint has the same points value. Your mission (should you choose to accept it) is to get as many points as you can in the 90 mins. The advantages of score events are:

  • Each participant can choose where they go and how far they want to go
  • The format is ideal for learning and practicing navigation in a safe setting where if you get lost, relocating yourself on the map is easy
  • If you can't find or get to a checkpoint for some reason - no worries - just move onto finding another

This event will suit all. Those with little navigational experience can use the event to learn the basics. All The checkpoints are at easy to find locations - corner of field, where paths meet, stream junction, road t-junction etc. You will not need to go off-piste but stick to paths, roads and tracks.
Likewise expert navigators can use their skills to plan the optimum route and move from one to the other on the best line.

You can do this event on your own, with a partner or in a small group.

How do I get the 'app' and how do I learn how to use it?
You'll be able to download the app and the map you need anywhere that has WIFI or a good mobile signal (3g/4g). It's best to do this before leaving home but Cwmdu campsite has free WIFI and so does the Farmers Arms in Cwmdu. 

Below is a link to full instructions, however.... the app is very easy to use. Just press 'start' and it does it all for you. It starts automatically as you cross the start line, it recognises when you get to each checkpoint, records that you've been there and at the finish stops and uploads your time and score automatically to the overall results table.

Starting and Finishing.

This is a Start Any Where (SAW) MapRun event This means that you can choose which checkpoint will be your start and finish. Once you have pressed 'go to start' on your phone, simply walk to the the checkpoint you choose to be the start (for most this will be the road junction close to the pub in Cwmdu - marked S1/F1 on the map). When you arrive at the checkpoint the phone beeps/vibrates and the clock starts ticking.
You now have 90 mins to visit as many other checkpoints as you can .... and then return to the same checkpoint you started from when the clock will stop. You must return to your starting checkpoint to finish the event.

The MapRun app is particularly appropriate under the current Covid situation. It means walkers/runners can test themselves in a competition/challenge format without the need to gather in numbers.


For this event, each checkpoint gains you 20 points. For every minute (or part of) you are late back over the 90 mins, you will lose 10 points. 

Mountain Skills

The route is not 'technical', being mostly on pleasant paths, roads and tracks. You can get from one checkpoint to the other on public rights of way - roads, bridleways, footpaths, tracks. There are 26 checkpoints. They are all easy to locate, being on easily identified features - corner of field, path junction, building etc. If the visibility is poor on the tops, finding your way to the open fell checkpoints may require you to use a compass (you can of course choose not to visit these checkpoints).

Many of the higher checkpoints are in a mountain environment. These and the routes between are not suitable for those without the necessary mountain walking/running skills. You need to take with you appropriate equipment (clothing, footwear, navigational tools etc) and you need to have the right skills to cope with what could be very difficult conditions. Don't make the silly mistake of assuming that as it's hot and sunny in the car park that it will be equally pleasant on the top of the mountains.

If you are in any doubt about the above then make sure you go with someone (appropriately distanced of course) who does have the right skills.

Solo runners/walkers should (as always) let someone know where they are going and at what time they should arrive back. They could additionally leave a note in the windscreen of their car as to their intentions.

As well as using your phone to navigate by and to record your outing it is essential that you also have adequate backup plans for navigation and route finding - printed maps and a map and compass.

Printed maps will be available at Cwmdu campsite or you can use the map downloaded to your phone (or you can use both).

How to get the app and map ready on your phone:

Download the app from your fav place:



or search for MaprunF, by FNE Enterprises

You’ll need to set up the app with your personal details then download the map at home (don’t try at the venue as there is no mobile signal). To get the event map onto your phone, first start up the app then click:

Select Event - UK - Wales - South Wales Trails - Cwmdu West

The map will take a few moments to download. You can view the map by clicking 'go to start'.

At the venue just go the app on your phone. When ready for the off press 'go to start'. Keep away from the start checkpoint until you are ready to start. Walk/run towards the start checkpoint when you're ready and as you cross the start point your phone will bleep and you're on your way. All timing starts from the beep. Remember, you must return to this same checkpoint to finish.

If you wish, you can get the app to show your position on the map on the screen and leave a 'breadcrumb' trail of where you have been. Just go to 'options and settings' before you start and click 'display location' and 'display track'.

Many thanks to Pat Macleod (NGOC) for setting this route up for me.

Phone issues:
There are many different makes and models of phone. It's not possible go through all of the issues you might encounter with your particular one. However, here are a few general pointers:

  • Make sure your phone is fully charged before you set off
  • Make sure your phone will allow this app to 'run in the background'. This means that when your screen goes off (because you've turned it off or it goes to sleep) the app is still tracking your progress. In settings, go to apps and choose MapRun to see the settings
  • Make sure you have the 'media' volume turned up to max so you can hear the beep.
  • If when you get to a checkpoint your phone does not beep, it may be that your phone has gone to sleep. Just turn the screen on and wait a few seconds and your phone may then register the checkpoint.
  • If your phone does not beep when you get to a checkpoint it might be that your phone's gps is not accurate enough for some reason. If you walk around a bit and back and forth it may then register the checkpoint. Older phones can have this problem sometimes. You can go into settings to check that you have the highest possible gps accuracy - this is often under battery settings as a higher gps accuracy is more demanding of battery power.
  • If your run does not upload to the overall set of results after, it may be because there is no phone signal. Don't worry it should automatically upload when you are in a WIFI zone or a place with a good 3g/4g signal later. If it doesn't then you can try a manual upload. If you still have problems the organiser can add you to the results if you send him a gpx file of your route.
