ATTQOTD: I do almost all my runs in the morning, generally as soon as there is enough daylight to make it safe, so the start time shifts later and later. Like
@KSellers88, I'm not going out on our country roads with a headlamp. At some point (maybe), the temperature becomes the limiting factor, so even if the sun is up, I might wait around for it to warm up.
Since we were talking about bad runs earlier, here's how you can talk yourself into and out of a bad run, all on the same run:
Today's schedule called for 2WU+5x1@HMT/.25RI+2CD, for a total of 10 miles. Before I started, I had talked myself into wimping out: T+D 145, calf and Achilles hurt, tired from yesterday, no 'A' race on the schedule, etc.
The WU felt OK, so I talked myself into just one of the HMT intervals and the rest can be at easy pace. The first interval went OK, so I talked myself into just one more... until I completed all 5. I nailed all 5 of them! By 'nail', I mean 'did them too fast'. If I end up between un-adjusted and T+D adjusted pace, I consider it a win.
Full disclosure: I did cut the CD short and ended up at 9.4 miles instead of 10. The good news is that I pre-made it up yesterday, by misreading the plan and doing 6 instead of 5.
Lesson learned: sometimes your body lies to you during the first mile. Finish the first mile, then decide if you're up to the rest of the run.
