What you’re in for
The Weekend Saunter format: five, ten or a half at your own pace on a weekend morning, with places on the day. It is the gentlest thing on the Grim calendar, meant for a first race or a long-run-with-company rather than a time. The course is the Huddersfield Narrow Canal from Slaithwaite — Slawit to anyone local — up the valley towards Marsden and back, an out-and-back turning at a marshal. This stretch climbs lock after lock, so the way out is uphill and the way back is not, and the organiser calls it the most undulating towpath they have. Registration is at the community centre on Bank Gate; the start is on the canal outside Waves.
Terrain and trail
Towpath that varies from surfaced to grass and stone, with a ramp at every lock — and there are a lot of locks between Slaithwaite and Marsden. It is still a canal, so nothing is steep for long, but it is not the flat towpath of the Leeds & Liverpool events, and a long day here is a harder day. Wet and muddy in the low sections after rain; the winter edition can be icy. 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.
