I finally got out of my house after losing 200 pounds and i want to be the first to mountainclimb while (cont)?

eating 1 pound of cake batter each hour. has this been done before? what preparations should i take to complete this task? ive consulted with my physician, and he said its fine, but im also about 300 pounds overweight for this task. i am currently 500 lbs. what kind of mountaincliming wheelchair should i purchase with the money i got from my megafatt 14 person streetlugeing contest. it was an easy win becaus of my extreme girth, i got down the street so fast that the wheels fell off.
