Improvement is an inherent challenge of the multisport culture. Many multisport athletes prepare for their events based on training traditions developed in the individual sports of swimming, cycling, and running. These traditional methods are rarely grounded in sports science and are not effective for combining two or three disciplines in one competitive event. The Triathlete’s Guide to Run Training is one of the only books that is written for the multisport athlete looking to become a faster, more efficient, and stronger runner.
