I wouldn't start at the front. Unless you can maintain that speed, you will be passed by a lot of riders, and that's where problems can happen. Start near the rear if it's a mass start. Stay to the right and ride predictably. Call out/signal road hazards and when you're slowing down, stopping or turning. Also call out approaching and overtaking cars ("car back," "car up," "car passing"). Keep an eye our for riders overtaking you, as well as advancing cars before moving out of your line. If you ride predictably, stay alert, and announce what you're doing to other riders, you should be okay.
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.
