I always kind of thought that running was a great activity because it didn't need much equipment. That may be true if you're young and/or not running very far. Training for the marathon has caused me to get many items to help me get through the training and the actual marathon.
Body Glide. It's like a very, very soft candle in a deodorant tube. It helps avoid chafing. I use it by my bra.
My sports bra. It's something that Jane Russel and Howard Hughes would approve. I did a lot of research to find one that would really work and after seeing other women running on the path, I'm glad I made the investment. Very often I see other women running and I just want to cross my arms over my chest in sympathy pain. No, I'm not going to show a picture of my bra, just thought I'd share a younger, less fundamentalist Jane Russell.
My new foam roller. It's designed to massage muscles in the legs and back that are hard to massage on your own. I've had tight/sore calf muscles since early last week. They feel better after I start running, but stiffen up the minute I stop running, so the first steps really hurt. I tried my roller yesterday and it worked wonders on my calves. The roller can also be used for strengthening and I will try that out tonight with my cross training.
Interval Watch. Because we do 5 minutes run:1 minute walk intervals, I needed a watch that had intervals, something I didn't have. I ended up buying a men's Timex Ironman watch because it has memory for enough laps. It's really nice when I'm out running to have the watch tell me when to start walking and when to get running again.
This doesn't count the non-cotton socks, shorts & shirts that are needed. I had the shirts, but have purchased many socks in the last few weeks. I'm sure there will be additional products being purchased before the marathon in November, including a new pair of running shoes, but these are the only items that were needed and not all were expected.
