The Trinity Challenge will serve as a pre-summer tune-up in hopes that the consecutive days of hiking will allow participants to ramp before the Sierra Challenge. This mini-challenge is open to anyone who wishes to participate, whether for a single day or all three. This is primarily a wilderness experience, and as such there are serious risks involved that are the responsibility of each individual participant to manage for themselves. There is no water, food, first-aid stations, emergency services or shelter of any kind available to those in trouble. The Trinity Challenge is not a formal organization or event, but rather a haphazardly chosen list of random peaks. Hence, there will be no official support structure available to participants in case of emergencies. If you are uncomfortable accepting such risks in any way, you should not participate.
I will not formally track those who are attending this event. If you wish to join, I plan to leave from the designated trailhead at 6am. Route information can be found on each of the peak pages.
