If the hunters are not in good shape, and even if they are in good shape, my advice is they rent a couple of horses and let them do the work. Like mentioned above, it isn’t worth a heart attack, or your partner missing his valuable hunting time. Where I live in Montana you can rent horses (4) and a wrangler to retrieve an elk for $300-400, depending on how far the elk is from the trailhead. They will trailer the horses to the trailhead, you lead them to your elk, the wrangler guts and quarters the elk, if you haven’t done it yet (which I don’t recommend), loads it on the packs horses, and then you and him ride to the trailhead. Meanwhile, your partner who hasn’t got an elk gets to make good use of his limited hunting time and hunt elk instead spending a day or two working his butt off packing out your elk.
