My name is James. I have done 2 challenges in the past. I had a good effort in the first. However, i was severely hindered after the birth of my first child for the second challenge. He likes chocolate, so do I. This winter I have felt my extremely high-powered snowmobile struggle to pull me up hills that it once did with ease. There are no more additional performance parts that can be installed to increase power. The only variable I can change is the rider's body weight...that why i'm here. and because i'm chubbier than i should be and feel like a slug. Good luck. When the sledding gets tough, just close your eyes and grab full throttle. or something like that.
