I'll refer you back to Shato's post here. Talk to your doctor before you start training or have put a deposit down for something like his. Elk hunting is the most physically demanding of anything short of mountain goats or bighorn sheep.

There's an older guy I keep seeing in the mornings and evenings here out running with a pack on his back. I sort of figured he was getting ready to hunt goats or sheep. He told me a few days ago thathe's getting ready to hunt elk.
