Here is a recently uploaded video of the second half of one of the greatest marathons ever run. This race was just a few months after the Salazar/ Beardsley Duel in the Sun. Start at about 57 minutes if you want to watch the duel and race to the finish.
From the Youtube video:
The race that stopped the Nation ... October 8, 1982 ... Robert De Castella was the favourite to win the marathon at the 1982 Commonwealth Games in Brisbane. At the start of the race, Tanzanians Gidamis Shahanga and Juma Ikangaa raced to the lead and were 50m ahead of the pack after five minutes. After the 20 km mark, this gap had widened to several hundred meters. By the 23 km mark, Ikangaa had taken the lead from his compatriot, with de Castella in the main pack some 250m behind, but closing. de Castella passed the now tiring Shahanga at the 38 km mark, and in the next kilometre drew level with Ikangaa then took the lead. However Ikangaa was not done yet, and re-took the lead slightly. The duel continued for the remainder of the race. Eventually de Castella pulled away, and won by 80m in a time of 2:09:18, 12 seconds ahead of Ikangaa. Briton Mike Gratton finished 3rd in 2hrs 12min, 6sec, and Shahanga faded to finish 6th. The race finished on the streets of Brisbane, not in the main stadium.Deek's Golden Day recent article and video where Rob De Castella recalls his famous sprint down Brisbane's iconic riverside road.

From a letsrun thread on the race video:
I still think the most interesting and captivating time of the marathon peaked in 1984 at LA and this was part of it.
