Thursday: 5mi EA treadmill. Yes. This felt fantastic. Tried walking for 30sec at the end of each half mile instead of 1min-ish at the end of each mile. Can't say if it really did anything beneficial, but my brain appreciated the change. AVG HR was 134, which is so so so close to me getting these easy runs into zone 2 for average. My HR comes down really quickly during the walk breaks now, so that help push the average down. But now that I look at it, during my Monday run, where I walked at the end of each mile, my avg HR was 140. So maybe the more frequent, shorter walk "breaks" are beneficial?
