I've had to pull out of the full marathon due to illness, and have contacted the organisers to pass place on but they've suggested I post here also.
We have booked a holiday cottage in Dolgellau for the Friday and Saturday and coukd transfer this, too, if required - very reasonable and picture-perfect Snowdonia stone cottage and the owner is also participating in the race so can act as guide.
In box me for details if interested.
