My sister recently came back from travelling with an idea to raise money for cancer research in memory of our nan who died almost ten years ago. Now I'm all for raising money but she wants to cycle from one end of the country to the other! I don't have time to train for this sort of thing and the cycle itself will take a week! The idea of leaving my baby for a week fills me with dread even though he will be one by then but my sister won't stop going on about it and she makes me feel so selfish! Would you do it?
