Things could be tough going; the outlook for Saturday in the Dales from the Met Office says:

Cloudy and wet with rain for most of the day, some of which could be heavy. Widespread hill fog and poor visibility. Strong and gusty northeasterly wind
Ignoring the heavy rain and strong wind for a second, the poor visibility could make things more than tricky on the navigation front. I reckon I know the first 35 miles left, front and sideways so the visibilty doesn't really worry me there and, at a push, I can hopefully muddle over Dodd Fell and Fleet Moss although that last checkpoint before following the track down to Cray could be fun to find, especially as other runners will be well spread out by this point; I know one runner got disqualified for not finding it last year and that was in broad daylight!

Buckden and Great Whernside again I'm fairly okay with too although funnily enough the bit between Capplestone Gate and Yarnbury worries me a little; was this the bit that was marked and had lights last year?
