It's possibly not that easy. Cyclists try do draft when possible. When there is no wind, or the wind is from ahead, it's simply: ride behind the rider in front of you. But when the wind comes from the side, it's best to position yourself somewhat to the side of the rider ahead. In my experience (but I have to admit I my experience is quite limited) it's actually surprisingly difficult to find the best position in that case.
