Event

Sithee at Slawit Again is a trail running event based in Slaithwaite, Huddersfield. The course starts and finishes by the canal near the village and runs out to Tunnel End, which includes a 3.5 mile tunnel under the Pennines. The route follows a notably undulating stretch of the Huddersfield narrow gauge canal with many locks. Feed stations are normally placed around every three miles and the event operates a cup-less policy, so runners are asked to bring a reusable cup or bottle. Marshals are stationed on the course and a 6.5 hour cut off time applies. The races are licensed by the Trail Running Association. Finishers receive a bespoke medal, drinks and food items.

Practical information

Registration, toilets and bag drop are at Slaithwaite Community Centre on Bank Gate. Parking at the canal start finish is very limited; additional parking is available in town carparks and side streets. A train station is available in Slaithwaite. Transfers can be self-served within 48 hours and runners should notify the nearest marshal if they need to retire.
