Yes! Both the normal route and the arete. If you have decent fitness the normal route shouldn't pose any challenges, it's a long hard walk but not technical. Be ready for any weather on the top! It's worth doing overall
That said, mountain fitness can be quite specific. I have a couple of friends who are both sub 3 hour marathon runners and retired competitive hockey players and they are utterly unfit to walk up hills. They really struggle on even a few hundred metres of elevation difference.
