I did it, my leg where tired but I went anyhow and ended up walking about ½ of it, which is fine. The goal isn’t distant or speed rather just doing it. I admit it feels really good to get out the door. I think my legs look really thing and it is still a bit surprising and I feel lighter on feet after losing the 65lbs.+
I have always run /exercised in Asic running shows the fit my wide FAT feet and I will continue with these. As for tracking programs I am using Runkeeper and I have been for a long time. They have a nice mobile app and a nice web site.
