First of all, congratulations on losing 100 pounds. That is a huge accomplishment, I’m sure riding will help you to keep it off.
Many times I’ve been bringing up the rear in a group and when we stopped I asked if they had seen the elk, deer, moose, etc. They said no because they were going too fast and concentrating on the the trail and and keeping up with the person in front of them and missed it. Such are the missed moments of competitiveness. Stay with what got you here.
