OK, I'm getting this one in quickly. I have fairyniamh down for the coming weekend (I emailed you, Fairy, so just let me know!), but I need volunteers to run the challenge for the first half of the year, so sign up here!
In your comment, let me know: 1/ How many weekends you can manage 2/ any dates/periods you CANNOT take
If you need any help deciding, or don't have a clue what running one will take, ask any questions here in a comment!
