A typical 25K training guide, such as those for trail races, covers a 10 to 12-week schedule focusing on long runs (up to 20 km), 80% low-intensity training, and cross-training. Nutrition strategies, including carb loading and intra-run fueling every 30–50 minutes, are crucial, along with specific race weekend logistics like early start times and mandatory gear checks. For race-specific participant guides, you can often find information on platforms like Eventbrite or through local event Facebook pages.
