1) Running in Colorado at 7000+ ft was DIFFICULT. Could not get enough oxygen. I live at 5000-ish ft so I didn't expect to notice a difference, but I did. I think I would feel like super-woman if I ever entered a race close to sea-level. SIGN ME UP!!!
2) While trying to do single leg peddling on my bike trainer yesterday, I discovered that a 'front-to-back, back-to-front' motion was much smoother than my usual 'top-to-bottom' choppy motion. It also used some different muscles. I hope that I discovered an improvement rather than something that will make my cycling even worse.
3) This morning I learned (sort-of) how to back stroke and breast stroke. Hopefully nobody will try to save me from drowning when I try these out again; I'm sure it looks like I'm in distress. I am happy to get one step farther from feeling like an imposter in the water. Someday, I might actually be mistaken as a swimmer.
4) As suggested by Vickie in a comment to an earlier post, I counted my steps yesterday to determine my running cadence. It is about 80-82 when I'm feeling okay. I bet it slows to a shuffle when I'm tired. I will try to keep that in mind and count all during my next long run to see how it pans out.
