Please help her to meet her target of £2620, £100 for each mile on the day.
Many of us are missing Rachel Smith, a mum and Liberal Democrat activist who passed away from this awful disease last month. We miss her kindness, thoughtfulness, positivity and sense of fun.
Jo wrote on Facebook about her 18 mile training run on Sunday. That's about the same distance as it is from here to the other side of Edinburgh. Not for the faint hearted, especially when you think about how cold and wet it was.
Good luck to Jo - I'll be cheering you on from the comfort of the sofa on the day.
