As we move into the latter part of January, many endurance athletes are starting to plan out their season and getting back to their "base" phases. For many athletes, there is a great benefit to running an early season winter marathon.
Not only will running a winter marathon help to improve aerobic capacity, it will also allow the athlete to create a huge base for the run and help the athlete to more quickly build speed for the run. This base will translate to more speed on the run and also help with the aerobic base for the swim and the bike.
Many triathletes and duathletes, including many of my athletes, run marathons during the winter. This is a great training exercise and also a great way to establish a goal for the winter months. Check out this article with more information on how and why to train for a winter marathon.
