The Difference Between Body Weight and Body Fat on Race Day Compared to Off Season Training

When i'm at race weight, it's after a really big build up where i might be running 100 miles a week for a stretch. So if i have a couple of extra pounds going into the season that i can just kind of like chip a way at over the build up, it's just bit of a buffera. Means little less i have to try to focus on getting in i when i before i get down to count of tha, that gold race weight. What is your plan to maintain ideal body weight during the transcontinental run?
