The Mighty Deerstalker

Traquair House, Innerleithen, Saturday

If you're the kind of person that laughs in the face of dirt and regular soakings in the name of fitness, this off-road running event, declared to be the toughest in the UK, could be for you. The race involves navigating a course strewn with punishing natural and man-made obstacles at either 5K or 10K distances, the latter tackled after dark. The fun part? Participants are encouraged to do so dressed in tweed. Cost is £50 for the 5K and £60 for the 10K - last year sold out, so don't hang around. www.mightydeerstalker.com

The Spirits of Newhailes

Newhailes House, Musselburgh, tomorrow

Something of a hidden treasure, Newhailes is a surprisingly well-preserved 300-year-old neo-Palladian villa on the outskirts of Edinburgh. With deceptively large grounds and enough rough edges to make it interesting, Newhailes is also the perfect place to be scared stupid - as is the aim of this special Friday the 13th storytelling tour. Exploring the property's darker side - spirits, curses, witches, massacre and death - the event is suitable for over 8s and runs in three slots from 6pm. Tickets for adults are £13 and children £7. www.nts.org.uk/Property/Newhailes
