The Boston Athletic Association has a proud tradition of extending the challenge of the marathon to persons with disabilities.

Beginning in 1975, when one wheelchair racer completed the distance, the Boston Marathon has helped change public perception, providing opportunity and inspiration to a generation of new athletes. From its inauspicious origins 29 years ago, the Boston Marathon currently supports a wheelchair division, a visually impaired/blind division and a mobility impaired program.

Following the historic breakthrough in 1975, the Boston Athletic Association embraced this competition and incorporated it as part of the Boston Marathon. The wheelchair division quickly became a focal point of local, national and world interest.

In accordance with the existing divisions of the Boston Marathon, the wheelchair division similarly adopted qualifying times that have served to motivate aspiring athletes. With the exceptions of the Olympic and Paralympic Games, the Boston Marathon is the only race in the world requiring a qualifying time. With the emphasis on performance, the wheelchair division of the Boston Marathon has witnessed an unparalleled level of excellence in the form of world, national and personal best performances.

The introduction of prize money in 1986 enhanced the competition, and provided the wheelchair division of the Boston Marathon with the richest prize purse in the sport.

This athletic phenomenon and subsequent successes of the wheelchair division provided hope and possibility to additional audiences with disabilities, who were eager to accept the challenge of the marathon distance.

By the mid 1980's, the B.A.A. established a visually impaired/blind division and a mobility impaired program. In each of these new components of the marathon, realistic standards and criteria of competition have been established.

To date, thousands of people with disabilities have competed in the wheelchair, visually impaired/blind division and mobility impaired program.

All individuals with disabilities must follow entry procedures and qualifying standards of the B.A.A. For persons with disabilities, the Boston Athletic Association follows the rules and guidelines of the International Paralympic Committee. Medical documentation for disability classification must be submitted with the entry form.
