This is the second time I have used Active trainer to prepare for a Half Marathon. I have to say this time I did not feel I was prepared enough for this race despite completing nearly all the training suggested. One of the reasons is that the course for the Half Marathon this time had many more hills then the program suggested I do. I ran the Miami Half last time and the I chose a different program which I felt worked on speed more and really had me better conditioned for the race. Needless to say I was disappointed this time.
