I have a question for any runners or fitness buffs. My 14yo daughter just qualified for the state Cross Country meet. We live at 1280' elevation, and the meet will be held on the other side of the state at about 3200'. Obviously, going from sea level to Denver would be tough, but will this elevation difference be enough for her to notice? If so, anything special she should do to train for it? She only has a little over a week. Thanks.
