You can meet other runners/walkers working on their 50 state challenge through the Half Marathon Club. This web site also has a page to search for races. If you join the club, you can get discounts on race registrations too.
Team Wil-Sun is a husband-wife team that is working on the 50 states and a bunch of other crazy funatical runner goals. Their blog has great ideas for races.
Mileposts is another of my favorite blogs. Dorothy is a writer, contributing blogger to womensrunning.com, USATF Level 1 and RRCA certified running coach, Garmin Brand Ambassador, small business owner (dreambigrunlong.com) and a mother of 3. Who says you can’t do it all?
Jeff Galloway has written books on using the run-walk-run method to complete a marathon. If it wasn’t for the Galloway method, I would still be sitting on the couch.
Traveling with Marathon Tours is an easy way to run the most popular marathons in the world. They have a terrific staff of experienced travel runners to make any runcation into an adventure.
The Marathon Guide is another web site with information about races and race reviews from runners.
