Last month, one of my sons completed the Seattle to Portland bike ride and I was at the finish line in Portland to see him complete it in one day (205 miles). I want, very much to complete that ride at his side next July. I am sixtythree and in pretty good shape. I ride approximately 75 to 100 miles a week but the longest I have gone is 63 miles in one ride. I have a year to get ready but I need help on just how I should prepare for this. My son is 34 and he rides about 17mph average. When I do my usual 20 to 30 mile rides, I go about 15 to 16 mph average. One problem that I have experienced with my riding (other than needing an ass transplant after my 63 miler), is that I find that I am pushing down on my handlebars more than seems normal and my arms are straight and it just feels like I am doing one long pushup. (Should I raise my handlebars?) Thanks in advance.
