Can anyone with more fitness experience than me advise whether training for a marathon and the AOSB at the same time may be a bad idea since they both focus on a very different kind of fitness? I am thinking that the marathon training will give me a good endurance base but also considering whether it will take up too much time and leave me under-prepared for the AOSB. Chances are I will train for the marathon regardless but responses here may help me tailor my program so that my performance at the AOSB (main priority) does not suffer. Any advice? Cheers, J.
