No reviews of the Moonlight Meander, and nothing on what people wore. Both are things no organiser publishes and every runner wants before they enter — how it actually went, and what was on your feet.

What you’re in for

Swinsty in the pitch dark on a November evening: one or two laps of the 3.3-mile woodland loop by head torch, fairy lights and whatever else you bring. Registration from four. The course is the 6.7-mile loop of Swinsty and Fewston reservoirs in the Washburn Valley above Otley, a figure of eight on the well-kept perimeter paths, with the shorter events using the 3.3-mile Swinsty half of it. Pay-and-display parking at the North Lane car park next to registration.

Terrain and trail

Well-made gravel and tarmac reservoir paths with short woodland sections, tree roots, a footbridge or two and a couple of gentle rises — undulating rather than hilly. Fast, dry ground most of the year and the prettiest Grim venue in autumn. Wet leaves over roots are the thing to watch in November. In the dark the roots and the footbridge steps are the whole difficulty; a decent head torch turns it back into the easy path it is by day. The events are cup-less, so bring your own cup or bottle for the water at the finish. Over-ear headphones are not allowed, and there may be an unmarshalled road crossing.

Three reservoirs, one long run, and some of the best-maintained trail surfaces in the north. This is what you do when you want big distance without big hills.

Two reservoirs for the price of one, connected by well-graded Yorkshire Water tracks. Quiet, well-maintained, and a reliable choice when everywhere else is ankle-deep.

Thruscross Reservoir from BlubberhousesMODERATE
Thruscross Reservoir from Blubberhouses
13.5km · 162m climb · Loop · 2.3km away
The middle option in the Washburn Valley reservoir series - more commitment than the short loops but less than the full three-reservoir circuit. Thruscross from below gives the valley its proper context.

Swinsty Reservoir LoopEASY
Swinsty Reservoir Loop
6.3km · 27m climb · Loop · 2.3km away
The smallest of the Washburn Valley reservoir circuits. Straightforward, reliable, and the kind of route that gets used regularly rather than just once.

Simon's Seat from Thruscross ReservoirVERY HARD

28.7km · 828m climb · Loop · 4.8km away
This route crosses two distinct landscapes in one loop - the flooded Washburn Valley around Thruscross, then the high gritstone fell of Simon's Seat - with barely any road between them.
