Oh, it definitely is realistically possible. 5K is a "fun" distance - we (wife and I) always enjoyed them. We never felt the need to enter any longer events, as we just wanted to have some fun.
Now to see how long I have to be in rehab before I can jog again. So far, on my own, I've been able to alternate quarter mile segments (walk a quarter, jog a quarter), but that's my limit. I'm thinking that between the metoprolol and the 130 BPM maximum setting on my pacemaker, that I'm stuck where I'm at until something is changed for me. It feels like an external limitation, not my lack of conditioning. Will have to wait and see. In the meantime, Cooker, please carry on for me and I'll catch up with you when I get back on track.
