At first, it looked as if he finished 6th but a Japanese athlete who was in 3rd place was subsequently disqualified after he had been found to obstruct a Canadian competitor. After another appeal, the Japanese athlete was reinstated so Rob was 6th.
The second Irish athlete was Brendan Boyce who finished in 19th position with a time of 3h 53m 59s. This top 20 finish is an improvement on his performance at the London Olympics where he finished in 27th place in a time of 3h 55m 01s.
The third Irish athlete Alex Wright had to pull out after 30km, perhaps a sign that he hadn't fully recovered from the 20k race last weekend.
