I walked nearly every day through TC. I couldn't manage to do much more than that some days, and I found I was completely stuffed in the afternoon regardless of what I did in the morning. So, if I could drag myself out of bed, me and the hound would be walking up the bike track before dawn.
It's really good for you on both a physical and emotional level. Evan though the TC, which is diabolical stuff, slowly seized my feet and legs up I found that after a couple of hundred metres I'd be moving more freely. Chemo in summer sucks, so being out in the cool predawn air was a relief. It still is.
