Today was my first ride of the week. I took Monday off to paint and was too tired/fatigued on Tuesday and Wednesday to ride. I think the fumes must have gotten to me since I was lethargic, light headed, and crampy for those two days. Finally, I felt well enough to ride in this morning. As it turns out, I missed the hottest days of the year and had a beautiful ride in. It really ocurred to me just how much I love my commute, I felt part of things again. I was so detached from things in my car. I've also been using my HRM everyday, it's giving me a lot of useful information such as: my morning commute was averaging just 22 minutes door to door, and that I've largely been riding out of my most productive weight loss zone. I've already lengthened my ride and am targeting a specific zone to encourage more weight loss over muscle/cardio building. It fits more with my "commute as training" philosophy. Now I'm shooting for, at least, a 30 minute ride with a minimum of 70% of my effort ocurring in my optimal training zone. I haven't used it mountain biking yet, I have a feeling that it will blow the thing up.
