Sunday Speed

 12K logged on my meal break today.   Was going to do an extended " heart run" but the HR was lower today and it felt good so it ended up being a bit of a dry run for my upcoming 10Ker in a couple for weeks.   Started off at a 6:00 pace working my way up to a 5:00 pace over the first 2Ks.  Between 2 and 4K I worked up to a 4:45 pace and held until 5K where I cranked it up to a 4:30 pace then held it there until the 10K mark where I geared it down over then next 2Ks.   It all felt pretty good,  a little hot and a small tweak in the right calf otherwise A OK.
