Do it. What's the worst that happens on the Beast?
You walk up it. It's no big deal, and you likely wouldn't be alone. But you might end up surprising yourself, too. If the whole ride was comprised of bad hills, I might encourage you to skip it. But one short hill that might be beyond your current ability is nothing to really worry about. Just make sure you're in your smallest chain ring and then make use of your smallest gears. Pace yourself and try to relax. Fourteen percent is relatively steep, but it sounds like it's short, so you either try your best to gut it out or you walk. Then you train and try again next year!
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
