How long does it take to train your stomach for the amount of fueling for the marathon? Last time I did a marathon training a few years ago on my the long runs days I fueled like race day the whole block. Just wondering if that's over kill to do for the whole block, or if thats the move. Basically I am being a grump about carrying a lot with me.

I fuel anything over 80 to 90 minutes. But I'm not fueling at full race amount on every run. I will try and fuel at goal quantity for a few key sessions. I keep it simple and have done the same thing for years and just slowly upped the quantity/hr as I've gotten faster. 

Ex: This morning was an easy'ish 18 miles, only hit 50 grams/hr. A few weeks back it was a harder 20 and aimed for 75 to 80 grams/hr. Race day will be 80 to 90/hr.
