I tried a 12km run that was about half on concrete this week. It did not go very well. My knee has been complaining since then. I still did a hike/run the following day which went all right, though my knee was complaining some by the end of the day.
I'm going to try to increase my distance by 2-3km this week and get my exercise time up to 4 hours. I am planning on participating in the Aravaipa virtual half marathon in about 2 weeks. I will probably run it on the gravel trail through the Air Force Academy, as long as it is not otherwise closed.
Overall stats for the week are:
Total Distance: 25.4 km
Total Time: 3 hr 37 min
Elevation Gain: 314 m
