In the wake of explosions at the finish line of the Boston Marathon, it appears that over 10,000 runners had yet to finish and remained on the course.
Last year, the average finishing time of the 21,554 runners to complete the marathon was 4:18:27. The clock at the finish line when the bomb went off showed about 4:10:00, and CNN said that half of the 25,000 runners had not completed the race yet this year.
Officials stopped runners on the course in large numbers and diverted them away from the finish line.
UPDATE: Runner's World is reporting that 17,584 of 23,326 runners reached the finish line. Number does not include the many bandits that are known to run Boston unregistered.
