C.S. Lewis told us that Experience is the most brutual teacher of all but by God, you will learn. I've been training & participating in endurance sports since Fall 2007 and I have to say, I'm still constantly learning from my experiences on how to improve for the next time around. My first major lesson was learning to not over train and investing in sneakers that can actually support you. It taught me to cross train & realize when you want to do an endurance event - what you wear, really matters, it's not a 3 mile jog. Second major lesson - nutrition. Eating well, makes you perform well. Food is fuel & muscle recovery.
Third huge lesson - stretching & massage. I've been a lot better with stretching (I was horrible in this area until the last two months) but I never get massages. I've been told to by other athletes, my physical therapist, etc, to go once a month. It wasn't until I was practically wimpering & crying on the massage table this weekend I realized how crucial it is. I'm used to my IT bands hurting when I get a deep tissue.... but it felt like my neck had muscle growth spurts or something. Like, it was lumpy, and it was painful.
So - if you're training for something that's longer than 90 minutes, please learn from my experience & take care of your tissues! Trust me, you don't want lumpy sore neck.
