It was raining lightly when I left this morning. Quite a change from the warm, dry weather we've had for at least the last month. With the heavy cloud cover it was also very dark. After a mile and half warmup I pushed myself to threshold pace, which I sustained to the end. Definitely felt the strain by the end and was breathing hard, but felt pretty good overall (maybe just a little bit of lingering fatigue from Saturday's long run). |
