PM - after work - another busy day back in the office. I have been too tired in the morning to get up to do an early run - so my mileage will suffer a bit this week while I readjust time zones. This was a pretty good workout for me. 2 mile warm up and 2 mile cool down. 6 x 5 mins at threshold pace with a 1 min rest between. Have been doing similar workouts to this on the treadmill, but decided to do this one outside. The treadmill keeps me locked into the threshold pace of 6:21 to 6:24 but doing this outside was a bit of a challenge to find the right feel for the pace. The first 4 were well below that pace 6:07, 6:13, 6:08 and 6:18 with the last two at 6:29 which averages to 6:17 - and I was "feeling it" on the last two - hopefully still got what was intended out of this workout despite perhaps going a little too quickly.
Looked back at last year's workouts from this time period and this seems consistent with what I was doing then - though just going by memory of the workouts, I think I feel more depth to my endurance than last year at this time.
