I signed up for the Leadville Silver Rush 50 this year in July. It will be my first mountain bike race, so I'm looking for some suggestions regarding preparation. I can only ride on the weekends, but I have worked up to 42 and 43 mile rides the last 2 weekends, each with a fair amount of climbing (5K and 6K according to my Garmin Forerunner). Would it be better to start decreasing my mileage for the remaining weekends before the race on July 14? Or do a lot of you keep doing long rides up through the weekend before the race? I usually do my longer ride on Saturday and then a 20-25 mile ride on Sunday. Also, how much do people generally eat during during a race like this? I have run a few marathons in the past, and I usually eat about 4 gels during those, but a race like this will take significantly longer.
