Awesome! You are about where I am in my weight loss journey too - you should do fine, but I would make sure that you have water and snacks (Clif bar, energy bar, fruit, etc.) on board. The first aid kit I did have to use on one of my rides - goofy me - I fell off my bike while sitting still - redface - LOL. I carry an teeny little camera case with a few bandaids and a small tube of Neosporin. If there are rest stops, they will probably provide energy drinks and snacks. I would take something just in case. I am so proud of you and your daughter and wish you the best - it does sound like a fun ride - wish I could ride along with you! Make sure you let us know how it goes. You will be doing a century in no time! As far as weight loss, I am losing more inches since I started cycling. I still have to lose about 70 lbs. but I am definately feeling stronger with each ride - I just ignore my scale these days and ride for the sheer joy of it. I also give myself little challenges - like faster sprints - riding against my own time to complete a certain distance, etc. I believe the faster sprints (intervals) is what broke my last diet plateau. Hang in there - it will happen! Hugs!
