I'd rather be the last runner who saw a cool thing that everyone else missed, than to be a speedy runner who had a miserable experience.

There's not enough said about winter runing. Running in the winter is like not giving up when the road gets hard. It's about willpower and perseverance and being faithful to your sport.
If it's a nod from society you're looking for, run a marathon. But if it's a life-changing experience of personal strength and perseverance that you want, finish an ultra.
