I did a cyclocross race last weekend that was routed over a very bumpy mole-infested grass field. I ended up getting passed by a few riders on this section of the course. I was trying to stay seated and rest because this section was right before a big hike-a-bike and climb. Now I am thinking I was wrong in my approach, and that I should have grabbed a bigger gear and tried to stand up and mash through the field so I could use my legs as suspension. My back was killing me each time I got through. Anyone have any tips on riding something like this?
