i started running at beginning of last summer and would run atleast once a week with the goal of running a marathon in a year or two. at the end of that season i hit the 5-mile-per-run mark and pretty much didnt do anything the whole winter. This year I started early and hit that 5-mile-per-run mark and was finding it difficult to break. On my run last week I completely broke through that level and felt like I could run forever and ran 7 miles in an hour. The three days prior to my run I happened to only have one small meal a day (probably dropped weight by a pound or so, but I cant imagine schleping one less pound over 7 miles would have much difference on fatigue). On the day of my run I had a large gatorade an hour or so before I ran. During my run I ran a partially new course that was more hilly than my old course but the hills were less steep than the couple I have on my usual course. So, what do you think contributed to my successful run that day? edit: usually I run 2 or 3 times a week, but the week that I ran 7miles I had not run for the prior 6 days. cliffs: I hit a new 7 mile distance record on run. could it be because of me eating less earlier that week, drinking a gatorade before running, or running a new course? edit: updates in post 21.
