Keep in mind, too, that some groups ride are in a paceline formation. In a paceline, you typically ride very closely behind the rider in front of you, either in a long single file line or, if conditions allows, two abreast. Each person takes a turn "pulling" at the front of the line for a short period and then rotates to the end of the line. In a paceline, it's easily easier to go faster than you would otherwise ride on your own. But also keep in mind that it takes some pretty good bike handling skills to ride in a paceline. If you're a new rider, you might stick to rides where people simply ride together in a loose group. It'll get you used to being around other cyclists without some of the dangers that pacelines pose. That's how I started at first. I eventually progressed to paceline riding, which can be a lot of fun (and a little scary).
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.
