Denise,
I am training for IM AZ as well. It will be my first IM; I did a half last AUG in 6:00 but have no idea what will happen in the 'big race'.
I live in Sierra Vista. I sympathize with you; at this point (according to my guru Gordo's book) it is better to fully recover between key workouts. So do take the time you need!
I took leave from work last week so i could train hard...am in the Army so my training during the week is never as much as I think it could be. I did a long run, 18 miles, on Friday and was wiped out for the weekend. COuld only manage a short bike and run and swim, but yesterday I really felt recovered.
My training partner keeps reminding me, only 5 weeks left! Sounds like you are putting in the miles, putting money in the bank; it will come back to you on 9 April for sure!
Good luck with the training; go big this weekend!
Laura
