The Bath Half Marathon (also known as the "BATHALF") is an annual road running half marathon held in Bath, England, normally on the second or third Sunday in March. It has been held every year since 1982, except for 2018 when it was cancelled due to snow. The race was first run in the year after the first London Marathon in 1981 and has remained a popular race for runners preparing for that event. The next race is scheduled for Sunday 14 March 2021.
