Actually, it sounds like a huge deal to me. You should be celebrating As someone with knee problems, I told my husband when we first met (who was about to go running at the time) that I only run when being chased. Then I said, "no, on second thought, I don't even think that would do it. I'd just die a tragic horror movie death."
Congratulations!! Running is really tough but I find it's the one thing that I really find that works for me. I started off just jogging a mile and a half and started working up. Today I did 4.25 miles on the treadmill and I am entering a 5k soon! Who would have thought?! You can do it too!!
