As a young, optimistic and slightly unknowledgable high schooler, here is my prediction.
10K: KB and Mo Farah take the race into a league of their own and crush the field. KB manages to leave Farah in the dust running 26:21 to win. Farah comes in way behind in 26:34 with Merga trailing in 26:39.
The Gold in the 10,000 confirms KB's aspirations and he lines up for the 5K as well. Determined to redeem himself, Farah doubles as well. Running a race of their own, KB and Farah pull away from the field. Farah wins it in 12:44.59 with KB right behind in 12:45.11.
Thes are pretty much based on what I'd like to see happen and based very little off of facts, statistics or anything of the sort, lol.
All in all, KB remains unbeaten in the 10K and Farah still walks away with a gold and hero status back home.
