I am thinking of riding a MS 150 in Wisconsin next summer. It is a 2 day event. So about 75 miles a day. How would I train for this? I am just unable to spend several hours a day in the saddle. Could do a long ride on a weekend, but weekdays not so much. Could I run during the week as a cross tain and do me good? I run endurance races(1/2 and full marathons(mostly 1/2's)), so I can spend a few hours doing high output. I KNOW the best way to train is ride. Saddle time. I also got a pair of those Gel filled riding shorts. I like the "feel" of them, but they make my bum sweat. What is a good pair of long saddle time riding shorts?
