It's very important to properly stretch every day. Also, incorporating yoga, massage, and the occasional adjustment especially help when you are putting in the long miles for a half or full iron distance race.
My favorite place to go in town for a massage is Kinetic Bodyworks. Although they aren't all that close to where I live I will gladly make the extra trip to go see one of their massage therapist!!!! They have magic hands!!
For chiropractic care I like to go to City Center Chiropractic. They are very knowledgeable and give great adjustments!!
Using foam rollers, tennis balls (rolling your foot over it or rolling against one on a wall for your back), or The Stick on a regular basis also help.
