Ran alone this morning on the standard 10.04 course. On the way out got 36:47 at a fairly even pace after a very slow warm-up quarter in 2:10. HR did not get above 124 although it started getting warm. On the way back, felt like a short tempo to make things interesting. Decided to run a relaxed marathon pace effort not worrying too much about pace as long as it was faster than 6:00 for 2.25, and then sprint on the last quarter to see what I'd get. Did the first quarter in 1:29, then eased into a slightly over 5:40 pace. Ran the last quarter in 71, which gave me 14:04 for the run, 2:36 for the last 0.5, and 5:29 for the last mile. HR made its way to 154 prior to the kick. Total time for 10.04 was 1:09:33. Ran 0.5 with Julia later in the morning. In the evening ran 3.25 to DI and back. On the way out pushing the double stroller with Julia and Joseph, and accompanied by Benjamin and Jenny. On the way back, pushed the double stroller with Joseph and Jenny, and directed Benjamin as he pushed Jacob in the single stroller. Julia and Sarah ran/walked back behind us. This was quite a procession! Afterwards added another 3.25 at 7:30 pace. I am getting really odd results from the high mileage. HR at speeds slower than marathon race pace is down - that is to be expected. Threshold is not moved and sometimes I cannot even sustain it for long, pace, breathing, or HR-wise. However, the top speed is slightly better and easier to reach, and my kick at the end of a tempo run has improved. Has anybody observed anything of the kind, or would have an idea of what is going on?
