This year's Guisborough Moors is on the 14th April.
In the town we've had notes through the doors informing us of a bike race (East Cleveland Klondike) happening on this day. This will put Westgate (the town's main road) out of action all day, as well as a lot of the roads N and E of Guisborough under rolling road blocks, so I expect the town/A171 will be busy on the day.
If coming from the west I would suggest using back roads to get to the Rugby club on the day - eastern Hutton Road and Rectory lanes may be busy so I'd suggest taking The Avenue, Hutton road then through the houses (Aldenham Road/Eglington Avenue). If coming from the E Whitby road/Belmangate would be your normal route but is likely to be busy.
Details on the (bike) race are here
Not involved with (either) organisationally but thought I'd provide a heads up.
