Thanks for sharing your story, most people only share when they have success. Did you and your partner train together on the other hikes you did? When we train for Whitney, we don't just have someone do the 3 Saints as training, we do the 3 Saints as a team so we know what to expect from that other person and get experience with how they do on hikes like that. I would almost never go with someone I have not already done something like San Gorgonio or some other long/tall hike.
