Route: Shankill –> Rathmichael Woods –> Carrickgollagan –> Barnaslingan –> The Scalp –> Glencullen –> Three Rock –> Tibradden –> Cruagh –> Bornabreena Reservoir –> Tallaght (Shamrock Rovers) –> 2km toward home (main route as described here).
Time: 6 hours 3 minutes (excluding a couple of snack stops, maybe another 20 minutes)
Pros: Largely really beautiful, with the route taking in sparse mountain tops, forest walkways, some nice, runnable (if you’re fitter than me) hills, excellent views, and the odd nice village to travel through. The Glencullen Adventure Centre (a few kms before halfway) is a great stop off, really relaxed and with good coffee. The route is fairly well signposted throughout (especially well on The Scalp, where it’s necessary), with signs at pretty much every junction. There were large stretches on a Friday morning where I didn’t see anyone for at least a couple of kms, so despite being within the Dublin county boundary, this felt really quite rural. Check out the pictures – the first two-thirds of this route are genuinely lovely.
Cons: Everything from about 28km onwards except the Bornabreena reservoir section (which is maybe 2-3km long), is really quite dull, all little winding roads that are not the most fun to run or walk on. Given the choice again, I’d cut the route short at the far end of Cruagh, and visit Bornabreena another time. The roadside bit through Glencullen was busier than you’d like, too, even on a weekday. Only notable refueling stops are at about 15km in, in Glencullen, then you’re pretty much on your own.
Thoughts: This had been on my list of things to do this year (yes, I have one!), and was helpfully opened up to me by the combination of a very helpful wife, on pick up and drop off, and the opening up of the whole of County Dublin in the recent change to coronavirus restrictions. There’s no denying this is at the limit of what I’m capable of at the moment – it’s fairly comparable to the Wicklow trail run I did from Bray last year, though without quite as much elevation, and I definitely ran more of it, especailly towards the end.
Realistically, I need to be doing more things in the mountain and get more comfortable moving across rugged trails with uneven surfaces to get any better at this, but it was a really great experience, and I found I was only minorly hampered by having to carry a small bag with 1.5 litres of water, food, and other essentials in it.
The route is billed as a ‘1-3 day’ on the official website, but it’s definitely walkable inside a (long) day, and with a bit of jogging, within a shorter one. I was familiar with a lot of the spots – we’re regulars in Tibradden and Carrickgollagan, and less so in Cruagh and Ticknock, but I knew a few kms of the full route before heading out, which definitely made life easier. Maps recommended, though I only really consulted them two or three times just to check I hadn’t missed exits. There are signposts marking the whole way at either end.
