Watch this epic 4x400m relay showdown between NTC Elite and D2R. Both teams are right there until NTC Elite pulls away on the last straight away. The times both teams ran were pretty impressive this early in the season. Although the times can't officially go into the database because they were run by club teams they would be U.S. #1 and U.S. #3.
