Has to be triathlon.
Alistair Brownlee’s time of 29 minutes 7 seconds in the 10,000m of the triathlon was just 97 seconds slower than Mo Farah’s gold-winning time in the 10,000m Olympic final.
Brownlee swam the 1,500m in open water in 17.04. China’s Sun Yang won the 1,500m gold in the pool with a world record time of 14.31.
Brownlee completed the 43km cycle in 59.03. Great Britain’s Bradley Wiggins won gold in the 44km time trial in 50.39.
All of those are impressive individual times by any standard, but back to back they are incredible.
