I am also running a fall marathon (Detroit, Oct 15) and will likely have a rest period and ramp up similar to what @DopeyBadger said. Right now I'm questioning my sanity training for a marathon in the summer heat! At 5:00am this morning it was 73 degrees with Florida-like humidity - I was dying during my easy 3 mile run!![]()
I feel your pain. We are on day 3 of a heatwave here in New Jersey and it is supposed to break tomorrow. My "easy " run this morning was quite ugly! Hope it cools down a bit for you.

I can't remember if it was on here or the running thread, but someone mentioned changing their 7 day cycle to a 9 day cycle. This intrigued me quite a bit, so after doing some research, I decided to try the 9 day. I adjusted the Hal Higdon beginner marathon plan to fit a 9 day cycle, by adding a 30-45 minute tempo run and an extra rest day. So I have 8-9 days between each "long run." Anyway, I figured that you guys are the just about the only people that could be as excited at the thought of calendaring out their marathon training schedule as I am, so I wanted to share!
the entire time. He was worried
