I'm considering the two day off-road course at Geere SC and looking for any recommendations / suggestions. I'm new to GSA, just turned 2K miles. Still a little uncomfortable with the beast but gaining confidence. I'm 5' 11", 150 lbs, 73 years old. My 'main' bike is a R1200RS, which I absolutely love, but parking it for awhile to get familiar with my new GSA. Plan to ride TX, NM, CO, KS this summer. Mostly highway but surely some gravel / rocky roads in the west. I road these roads extensively forty years ago on my Moto Guzzi Ambassador, but haven't been off road in years, since I moved to Mass. Is this class too much for me? Anyone about my age done it? Any suggestions for practice / exercise ahead of class?
