O'Grady strongly recommends doing multiple 50 milers before stepping up to the 100 miler. In fact, most ultra runners will include a marathon and shorter ultras into their training for such an extreme distance. It's not recommended to go straight from running marathons to a 100 miler. When considering your first ultra, look for either a 50K or 50-mile distance. Practice this by including walk segments into your long runs. Walk early and often-every step toward the finish is a positive. While it may be an honorable goal to run the entire length of a marathon, it's not smart to attempt this in an ultra. Walking may be a four-letter word to a marathoner, but even elite ultra runners walk portions of their race. Most races have hills, so plan on walking up hills powerfully and briskly and running the downs and flats," O'Grady says. Often, runners "need to shift gears from running an entire marathon to running and walking the 50 or 100. These super long runs are kept at an easy pace with frequent walk segments.
