Hi Deb,
It’s my plan to get hit the trail by 6:30am. Each hiker will have the opportunity to carry the flag and will have a key role in getting it erected by noon! As far as finishing; each team member can choose when they leave albeit be willing to carry something back to the car. Some hikers are going to bag other peaks as well. I’d personally hope to be back to my car by 5pm at the latest.
I hope this helps!
