Katie Holmes has registered to take part in the Boston, Massachusetts marathon in April (08). The wife of Tom Cruise finished New York City's marathon in November (07) in five hours and 30 minutes. And, despite not meeting Boston officials' requirements to have completed at least one marathon in less than three hours and 40 minutes, Holmes has reportedly been given a pass to run the 26.2 mile (42.2 kilometre) race through the city on 21 April (08).
