Write a question about the following article.

For now , I ' m going to try to get back into doing some of my pilates / yoga / weight lifting DVDs and interspersing runs and walks when the mood strikes . Without such a lofty goal ahead ( which I always say will motivate me , but it never does ) I wo n't feel as much pressure to get out and run all the time . Maybe by this time next year I 'll be able to do 10 miles comfortably , which will set me up well for the half marathon . In other news , my husband and I will be leaving at 4 a.m. tomorrow to drive to Buffalo .

Question:
Why does the narrator need to get up so early ?
OPT: (I) None of the above choices .; (II) They need to go to pilates class .; (III) They need to fly to Buffalo .; (IV) They need to get ready for the marathon .;
