instruction: Based on the reference paragraph, when was the 149th Boat Race?
context: The 149th Boat Race took place on 6 April 2003. Held annually, the Boat Race is a side-by-side rowing race between crews from the Universities of Oxford (in dark blue) and Cambridge (in light greenish blue) along a 4.2-mile (6.8 km) tidal stretch of the River Thames in south-west London. The lead changed twice during the race, which Oxford won by one foot (30 cm), the smallest margin of victory in the history of the event. The close race has been described as "epic", while Olympic gold medallist Steve Redgrave suggested that the race was the "greatest we will see in our lifetimes".
