Tempo run on the Saucon Rail Trail, starting from the Town Park. 2.5 x 1k at ~5:00/km pace. Apparently the rail trail isn't flat where I was running, explaining the difference between times for the first and second km. Dropped about 10m on the first one, had to get it back on the second km. The additional 0.5 km was in the down direction. Upper 70s with some breeze.
