Physically speaking? yes, I can do that. I've done half-ironman triathlons and enjoy long physical workouts.
The altitude will certainly be a challenge, but that's why we are trying to do a day hike and two nights at altitude before starting the trail; if I feel bad I'll just turn around. I would like to summit, but not so badly that I wouldn't turn around if I was feeling nauseous. The climbing at the end does not look bad, but obviously the consequences of a fall are high. That being said, I'm totally ok turning around. I want to be challenged and have fun, summiting is a tertiary goal.
I'll look into the guide, and really would love to hire one, but I'm guessing it would be expensive. Thanks for your input though, I agree it is better to err on the side of caution with this type of endeavor
