Kidding. I enjoyed the leisurely pace of this run Tuesday after work, which felt relaxing and sustainable. I ran over South Table Mountain in Golden from west to east and back, starting at the Castle Rock trailhead and turning around at Foothills TH on the east.
Run distance was 8.92 miles, moving time 1:41, gain 1,063 feet. Average HR 132; even managed to keep it close to that on the hills.
It was a great day out, and I didn't quite have 2 hours to run but I tried anyway. The days are nice and long right now.
There were some freaky clouds this evening reminiscent of winter. It must have been windy and cold up high.
As I ran down the rugged trail in this "light", as usual I thought about injury and slowed a bit. However, with experience and a lot of evening runs, you just get used to working with very little in the way of visual cues; a certain fuzzy patch of brown that stays constant for 1/3 of a second is flat, a shape that shifts an inch in that time span is a rock, etc. You start relying on your peripheral vision, which is more sensitive to light.
I wanted 10 miles today, but I thoughtlessly didn't bring my headlamp and ran out of enough daylight to be safe. That includes both descending a cliff band in the dark and the native cats.
