And those two were against Bernard Lagat and Kenenisa Bekele. I doubt anyone ever won two gold medals in a single OG over stronger competitors.
And, oh, throw Eliud Kiochoge in there as well.
And that proves he doped, or what do you mean? In the 5k winning time was 13:14.39, 3k split was 8.10,89, Hicham running inside while Bekele and Kipchoge was leading, 4th km ~2.38, last km ~2.34, last lap "only" 52,93, the race was made for Hicham. The 1500 was harder case to El G but Lagat made the mistake when moved next to Hicham in the last 150m, running in the lane 2, instead waiting to the home straight behind Hicham and kicking to the win in the last 50m or so. El G knew what he had to do, and ran 1.48 the last 800m, 1.32,25 the last 700m (1.45,4 800m pace).
