No, it is not possible for each member of the Quintin Running Club to only run 1/4 mile in a 2 1/2 mile race. If there are 8 members and each member only runs 1/4 mile, the total distance covered by all members would be 8 x 1/4 = 2 miles. The race, however, is 2 1/2 miles, so there would still be half a mile left to complete.
