Slaithwaite, locally Slawit (Old Norse: Timber-fell clearing), is a village within the Metropolitan Borough of Kirklees, in West Yorkshire. Historically part of the West Riding of Yorkshire, it lies in the Colne Valley, lying across the River Colne and the Huddersfield Narrow Canal, approximately 5 miles southwest of Huddersfield.

Slaithwaite Hall, thought to date from the mid-15th century, is located on a nearby hillside. It is one of a number of cruck framed buildings clustered in this area of West Yorkshire. After many years divided into cottages, the building has been extensively restored and is now a single dwelling.

Legend has it that local smugglers caught by the excise men tried to explain their nocturnal activities as 'raking the moon from the canal' and definitely not as 'fishing out smuggled brandy'. A "Moonraker" is now the official nickname for a native of the village.

In February, on alternate years, Slaithwaite celebrates an 18th-century legend of Moonraking with the Slaithwaite Moonraking Festival, with a week of lantern making and a programme of storytelling. The week-long celebration, which always takes place during the school half term week, ends with a parade of lanterns around the village, and a festival finale by the canal in the centre of the village.

    Cracking little race company. They let me defer from a previous race to this one due to injury with no fuss at all. Well organised on the day, lovely friendly group of people. The course wasnt my kind of run, basically 4 10k repeats but it was a pretty, quiet section of tow path with some mud and incline which was great. Probably wouldn't do that run again but i'd defo do another 'grim up north' race.
  • Did the Half Marathon in 2018

    Had a great time as always, love these races always great people, and the best runs, iv done quite a few and have booked lots throughout the year, and love the cakes at the end lol
  • Did the Half Marathon in 2018

    The course was quite flat and now my PB trail HM time is quicker than my road!! Parking near the race start was a bit of a struggle just a minor niggle that won't stop me from attending next time
  • Did the 20mi in 2018

    Excellent race, I didn't necessarily like the loop but that's my personal preference, the race itself was well organised. There was enough stations although I would prefer crisps to jelly babies, again just my personal preference. Would definitely recommend.
  • Did the Half Marathon in 2018

    Lots of positives, only negative is that it was advertised as wasnt flat!
  • Did the Half Marathon in 2018

    The third Grim up North run ive done and it was well organised and communicated to runners in advance with kit advice from course checks by the organisers in the week before the race. Great cakes at the end and a friendly atmosphere all through the day. Consider where you place yourself at the start carefully, its right for the first few hundred meters when everyones setting off, I was too far back and had to stop a few times in first 500m or so while the field thinned out.
  • Did the Marathon in 2018

    Lovely day, I went with trail shoes but having had good weather, the course was probably better suited to roadies.
  • Did the 20mi in 2018

    I had a fab race, thank you for being so friendly. Fab trophy and race goodie bag.Perhaps knowing the course route beforehand would have been helpful as I reached a point and wasnt sure where I was supposed to go! Or having distance markers.
  • Did the 10k in 2018

    Wouldnt change anything, just go and enjoy.
  • Did the 10k in 2018

    Great atmosphere at the start/finish line, and though sections of the canal path were a little narrow which made the out-and-back nature a challenge at times, overall it was a cracking event!
