River basins of Ireland & UK

I really like this representation of the river catchment basins throughout Ireland & the UK.

Obviously there is an underlying message, if nature needs this amount of space to drain our land effectively, where are houses supposed to go? (that’s rhetorical) We know from the slightest heavy rain storm that we no longer have the natural water attenuation in our land as flooding is more and more evident – this is because of our built environment.

From an adventuring point of view the question is: is it possible to walk the length or breadth of Ireland cross country without getting your feet wet? 

I’m thinking initially something diagonal from Derry / Antrim to Kerry /Cork could be the way to do it but then you are dealing with the midland bogs too.

Either way, it is an impressive representation.

Arderins List of Summits in Ireland

Reading my Irish Mountain Log which just arrived and its great to see we now have an official list of the Arderins which are the Irish version of projects like the Scottish Munros where hills are defined by a set of agreed criteria.

The Arderins is a list of 406 mountains that are 500m or greater in height with a prominence of at least 30m.

One of the chief goals was to redistribute the foot load of our hills from the ‘main’ hiking areas of Wicklow, Mournes and Reeks which are very much over used and encouraging a more proportional approach to hill walking challenges.

The list of the 406 Arderins is here:

Like always though, access is a privilege and like all such cases when using the hills we should respect the landscape, the land owner and leave no trace just footsteps.

Route to Christmas: Day 1 2019 | World of O 

One of the best times of the year! December always brings a month of brain scratching from World of O with the daily navigation challenge. The link is at the bottom for you to try yourself.

How it works:

You are shown a map –

And, your challenge is to plot your route from (in this case) CP 3 to CP4 and offer some rationalisation for your choices. You can then compare your route to all the others that have been submitted.

If you want to check it out first the link is here

Otherwise my solution is coming next




My thinking on this is

  • to drop perpendicular to the contours until I hit the stream.
  • Fording the stream stay on that contour until I reach the trail
  • once on the trail I have a definite location (even though short) which leads me from the next junction
  • contouring around to miss most of the scramble and hopefully staying on more runnable ground even though I have to lose and regain height again.
  • the final approach is the hardest to identify as a definite though I’m again using contours and what I hope is identifiable land-shape to guide me in the right direction until I hit CP

Have a go and let us know how you got on in comments or on social media.

Off-season adventure racers, what do you do?

So you’ve had a busy year adventure racing and its winter. What do you do now? Feet up in front of the fire and rest?

There’s an old adage “Winter miles = Summer smiles” and its very true. Training and racing is a year on year activity. It’s not about starting in Spring and racing for the summer and relaxing in the cold of winter.

It is a multi-year round process of training cycles and possible multiple peaks for races through the season.

There may also be time in the winter to try more indoor activities that will complement your outdoor training and there is some great advice in the attached article from the Quest Adventure Series –

There are also big adventure running races (Art O’Neill Challenge, SPine Race) and other events (Causeway Coast, North Coast Trailquest) through winter that are more in the spirit of multiday racing for you to participate in or support if you are seeking your next inspirational challenge.

With my own 2020 calendar starting to take shape I’d love to hear what you have planned for winter 2019.



Bike Packing for ITERA 2016

07/06/16 – Post updated to include the ordering link.

So you’re counting down to ITERA in August and you have all your ducks in a row. Training is going well and you might even be thinking of your packing and gear lists.

The one thing you might miss out on, especially the domestic teams, is the need for a bike box. Because we are not flying anywhere and as previous domestic races provided universal bike transport boxes we may not have thought of it.

More routes to Christmas – Day 2 & 3

Did you have fun with the first maps?

Hopefully you are taking part in the daily challenge too on World of O. We’ll continue to post our route choices as it serves as a mental exercise for us too.

Routes to Christmas an orienteering visualisation.

You may have spotted a post on Facebook from us the other day about the Route to Christmas challenge on the World of O(rienteering ) website??

Well Mike and myself are having a bit of fun on the Daily navigation challenge, we each (along with 100’s of others) plan the route we would take to get between the Control Points (CP’s) and then to compare them afterwards.

We’re leaving a time lag between picking our routes and posting them so you can have fun with the other days too.

Here’s the map and link to Day 1:

Jan Prochazka gives us the introduction to the leg: As I am looking to the future, this leg is one of the best examples on the way towards EOC 2016. I have chosen one leg from the Czech long distance Champs 2015. There were about 3-5 interesting legs, but this one I did extremely well, and I was even surprised by the margin to the second best time. The terrain of Czech long distance 2015 was similar to EOC 2016 long. However, this terrain is situated on other side of the Jeseniky mountains and have in overall higher altitude. This leg comes up after 70 minutes of running, and its highest parts are over 1000 meters above see level – a last physically challenging leg of the course.

Our chosen routes:

Route to Christmas Day 1 2015 World of O News

Mike – Don’t fancy the leg sapping steep route. Contour around the tree-line and punch through the saddle.

Sean – Working across the contours will be quicker and using fences and streams as handrails to get to the second saddle where a sharp blast uphill will allow a direct drop down to the CP16

Bearing in mind we don’t have route maps or any information on restricted roads etc we are workign off our working knowledge of most likely case scenarios of race rules. No main road, that kind of thing. So either that road is out of play or Mike went for pints 😉

Stay tuned for Day 2 & 3 coming up as a double feature!
