I can also chime in with a few ways to get bargains on what others have commented on...
I am a run/walker, following the Galloway program, that started in Jan to do the March 2010 Princess. I am also super cheap.
1) Socks. I buy my coolmax socks at
Walmart, they have them for $2-5 per pair and they work just as well as the more expensive stuff. Through trial and error, I found that I need cushioned socks or I get blisters. YMMV. You can also sometimes find single pairs on clearance at Dick's.
2) Clothes. Kohl's is having a killer sale on running shorts, skirts, and tops, all under $10 each. Target has them for $9-15 regular price, as well. Make sure that you are getting the performance ones and not the cotton blend.
Also, TJ Maxx, Marshalls, Ross are good resources for clothes, sports bras, and socks.
3) Hydration belts. EBAY! Just type in fuel belt. I got mine for $9 shipped.
4) Garmin/GPS watch. If you have a GPS-enabled smart phone, they make apps that do the same thing. I have an Android based phone, but Blackberry and iPhone both have them too. I use RunKeeper, which tracks pace, location, route, elevation, and time. SportyPal is another. I also use an app called HIIT interval training to do my intervals.
5) Chafing. Invest $8-10 in a product called BodyGlide. Best. Stuff. Ever. Also works on a hot day if you want to wear a skirt w/ no hose.
I don't use a heart rate monitor, and I only use gels on run/walks of 9 miles or more. I prefer Gu, which you can get at Dick's for $1-1.50 a pack.
