Hi!
Good luck with your training! I ran a half marathon in GG Park last year and it was awesome... so worth it! Sounds like your training is pretty much right on schedule (Runner's World has the best tips / schedules to build on). The most important thing to me, that made me faster and stronger, when I was training was running hill repeats. Thought since you were going camping, it might be a good alternative to the treadmill run. Running uphill intervals (charging up, walking down) really helps build muscles and more importantly it teaches them how to recover. Sorry to hear you felt so fatigued during your 6 miler the other day. That is soooooo frustrating, I know. But you did the right thing, better to let up, recover and try again another day. Funny how us strong willed women have problems listening to what our bodies are trying to tell us. Sometimes if you feel depleted, try to look back and see what you re-fueled with and how soon you ate it after your workout. I know you probably already know since I think you read Runner's World but it is so important to replace glycogen stores in your muscles and do so hopefully within a 1 hour window of working out. I found that more often than not I hadn't either: 1) eaten enough the day before or 2) waited way too long after completing a run. No wonder my legs didn't feel like cooperating. Good luck with everything. Run fast. Can't wait to hear how it goes.
