Perfect weather for a jog. 5 miles. Max HR 146 average HR 134. I was happy to only need to walk a couple of hills to keep the HR down. The cross training is noticeable and I'm not half as unfit as I usually am after a break. If my foot doesn't devolve in to a pile of broken shards of bone- the plan is as usual... jogging at HR <150 (145 to start) as long as it takes to get aerobically fit. MAF test as soon as my 10 mile road loop is somewhat clear of snow.
