Perfect weather for my 10k jog. I was planning to run mile 2 as well as mile 4 this time and do 400 run steps/200 walk steps for the remainder. Not long after starting mile 2 I realised that the force was not with me, so I went back to alternating after half of it. Mile 2 is undulating, with a height gain of 70'; mile 4 which I did run all of again is a descent of 102'. I was 6 minutes faster today than a week ago, 6 minutes slower than my best ever last August.
