...I am not in any kind of shape to hike right now. I have tried a few times to train and battled fatigue from 8 weeks (40 treatments) of radiation. I am still easily fatigued so to answer wazzu's question "No I haven't started training for a marathon yet".
Congratulations!
One step at a time, Rod! Who needs a marathon anyways? You have proved your mettle.
What don't kill us makes us more strong!
