Not very. You need to be able to look after your personal needs and manage stairs. As a guide, if you can walk, say, half a mile you should be fine. If you are worried that this would be too much for you, but are still keen to come, contact us to talk about it as a lot depends on your individual circumstances.
We don’t want to invite someone who will find they are excluded from large elements of the course, but we aren’t working with athletes either!
