Triathalon training? Cool... I'm considering whether to buy a bike or really good walking shoes. One or the other.
How's your shoulder?
The soreness that was caused from softball is gone but the strange twinge that caused it is still there. Not much of an issue though. Just something to keep an eye on. I changed my pillow also. That might help.
The shoes are a lot cheaper. On the other hand bikes last much much longer. You should get both. They get different muscle groups and some days you feel like biking more than walking. Like if you have been on your feet a lot and they hurt biking can still be fun. I like both biking and running but biking is more entertaining.
