I've recently found a new goal; Ragnar Relay just added a trail version and it sounds ridiculously awesome.
Two nights camping and an 8 team, 15 mile per person, trail running relay. Non runners welcome to camp along in the village in support. There is yoga and a beer garden.
I'm eyeing the Phoenix one because it is local, but if any runners/hikers/campers here think it might be fun to do as a g2g I'd be willing to travel
