Castlewellan is a small market town with a beautiful forest park, about 45 minutes South of Belfast. It’s just a few miles from the coast, which made for a cool breeze on a warm day. The parkrun is in the Forest Park, almost completely shaded as it runs through a tree-lined path around a lake, with an extra out and back to add a kilometre.

There’s masses of parking in the park, though if you’re only coming for the run, the £5 cost might seem a bit stiff. Park in town and walk up one of the paths into the park, it’s only a kilometre or so. Or camp in the campsite next to the lake and fall onto the course in the morning.

The park is glorious. A nice 4k or so loop round the lake itself, paths to explore off to one side, and then a whole other area with multiple hilly routes to test you, running round and up/down Slievenaslat – you can see the start of the contour lines above the top right of the lake, above.


It’s a gorgeous run. It was entirely warm and mostly sunny on this lovely day, but even in grim weather you’ll have the constant distraction of great scenery. On a cooler day I might have wandered up the hill for the views, but was content to wander back, via the fields. I hadn’t originally planned to stay in Castlewellan, but my original accommodation cancelled while I was a few hours from the ferry, so booked in a rush. Having a parkrun on my doorstep was a bonus, never mind this whole area to explore. Obviously I recommend it.

The out and back is the toughest section. There’s the greatest chance of mild congestion as runners are on both sides of the path. And more importantly, it’s uphill all the way out. Yes, that does mean it’s downhill all the way back to the lake, but – uphill all the way. Gently so, but still. Phew.



Northern Ireland is not short of great scenery, but there’s quite a concentration in this Forest Park. Worth a visit on any day, but come along at 9:30 on a Saturday and you can parkrun, too. Lovely.
