The most critical aspect of planning a race strategy for an ultrarace is pacing yourself properly. Unlike a marathon, where you can push through the pain and finish strong, ultrarunning requires a more strategic approach. You need to pace yourself and conserve your energy for the long haul. Before the race, familiarize yourself with the course and the aid stations. Make a plan for when and where you will refuel, and stick to it. Be prepared for the unexpected, such as changes in weather or terrain, and adjust your strategy accordingly. Remember, the goal of an ultrarace is to finish, not set a personal best time.
