Over the last couple of months, I've compiled a fair amount of useful links pertaining to Running specifically, and fitness in general. In case they might be of use to anyone else, here are a few of them:
Route Mapping Sites
MapMyRun - A website that provides mapping tool based on Google Maps. The website also has a robust training log and a community forum.
RunningAHEAD - Similar to MapMyRun, RunningAHEAD features a running log and mapping tools, as well as a vibrant running community.
Running Articles
Runner's World - Companion site for the Runner's World magazine. Tons of useful articles, blogs, training programs, and training calculators.
Running Times Magazine - Resource for training plans, racing advice, road race rankings, guides to shoes, marathons, camps, etc.
Training Programs
Couch-to-5K - This is a pretty good beginner's program, and is the program I got started with.
Hal Higdon - The home of my current program, Hal Higdon's Novice 10K Training Program, as well as much, much more.
Jeff Galloway - Former U.S. Olympian, author of top selling running books, and designed of the run-walk marathon training program.
