I was able to take my over-ground walker to the trail today, and I managed to walk about a third of it. That's not the whole trail like I had planned, but it's a start. It added up to a thousand steps, which is more than I have been taking in an entire day. Between the Florida heat, and the fact that I didn't eat properly before I left, I just didn't want to take any chances on hurting myself because I'm stubborn. By the time I got back to the car and had to navigate the downhill slope, I was in excruciating pain, so it's probably best I only did what I did anyway.
That trail will be my measure of progress from here on. I know how far I was able to walk before sitting, and how far I was able to go before heading back to the car. Let's hope each time I go I can push it a little further.
