Dehydration ='s Legs of Concrete! 8/14/10

I think it's safe to say that the title says it all! I was severely dehydrated on Sat and paid for it during the 12 mile training that morning! I had my worse timing yet for 12 miles. I found myself pretty sick on the Fri prior to Sat's training and never took the time to properly rehydrate my body. Therefore while I was out there training at 6am on Sat morning I started out without any additional food (energy) in my system (due to fear of getting sick again) I only took in a bottle of water for the first 8 miles and at that point my timing didn't seem to0 bad. By the time I finished those 9 miles though I could feel in my legs and feet some crazy (different) pain than I had been accustomed to in the previous long training days. By the start of the final 3.1 miles my legs felt like I was carrying slabs of concrete and therefore my timing suffered! Bottom line...I gotta make sure I stay hydrated all week! So that on long training days my timing doesn't suffer! Still many high points being out there each week as well as this past week. The support from other runners/walkers training out there each week is always grrrreat! Many saying Keep up the good work, Nice job, Great work, You're doing it, You can do it...etc. I love how friendly & supportive those people are out there!
