We're going cycling in the New Forest tomorrow and we're trying to plan a route. My stepdaughter is coming with us and I want to work out how far we should go. We're planning on cycling for five miles, having a rest and picnic and then returning. The route doesn't involve any hills. Does this sound too far for an 11-year old? She's a bit of a couch potato, so propbably not that fit and she does moan like hell if we make her walk anywhere, but she is up for this. I don't want the day to turn into a moanathon, so would appreciate advice.
