I went for my 3d trail run today; been a little distracted by lots of cycling and my son visiting.
The shoelace trick worked. Now, I have to figure out why my knees are aching. It's not from running, it started before I got the trail shoes. I suspect it was the bike I had in France, with less lower gears and 170 mm cranks. That seemed to set me up for this, any time I do a lot of climbing, stuff at the gym, or running. I've been trying to wear flats a lot (not that I wear very high heels). It got really bad the day after I rode in 50 degree early AM chill a couple of weeks ago, then got better. Despite all of that, I still like trail running, although my running is not much faster than a hike. Interestingly, I can run up the steep hill fairly well, just stopping at the top for a bit to recover. Next time, I will go to a different trail. Just too lazy today to drive to a trail.
