Anyone who thinks Farah couldn't run faster is deluded but we only have pr's to go on so here's a comparison of their pr's and I don't think it's as wide as people are saying. I tried to remain impartial by giving them their best performances indoor v outdoor. i.e compare Kejelcha mile indoor(instead of his outdoor of 3:32 and Farah's indoor 2 mile instead of his outdoor 3k)
Kejelcha's 3:48i is equivalent to 3:31i vs Farah 3:28. Farah wins!
Farah's 8:03i is equivalent to 7:28i vs Kejelcha's 7:28. Tie game!
Kejelcha's 12:46 vs Farah's 12:53. Kejelcha wins!
Farah 59:22 vs Kejelcha 59:17. 5 seconds is nothing in a half. Tie Game/Kejelcha Edge!
Farah 26:46 vs Kejelcha ??:??. TBD!
Farah 2:05:11 vs Kejelcha ?:??:??. TBD
Not much difference there is there?
If we done a equivalent cumalative addition of their times.
Farah is 3 seconds faster at 1500m= equivalent to 10 seconds at 5k
Kejelcha is 5 seconds faster than Farah at half= equivalent to 1.3 seconds at 5k
Kejelcha is 6 seconds faster than Farah at 5k= equivalent to 6 seconds faster than Farah at 5k.
Even for argument sake, Kejelcha is .7 seconds faster at 3k than Farah= equivalent to .9 seconds at 5k
Total: Mo Farah is 1.6 seconds faster than Kejelcha in an equivalent cumalative race converted to 5k. If I chose Mo's official pr of 59:32 in the half, it would make Kejelcha 1 second faster in a Cumalative 5k race. For argument sake, if we split Farah's and Kejelcha's 5k pr and say that 5k race is 12:50. Here is the percentage difference between them
Using Farah's official HM PR= Kejelcha is 0.00129870129% faster than Farah
Using Farah's unofficial HM PR= Farah is 0.00207792207% faster than Kejelcha
No matter what distance you pick to get that converted equivalent, those percentages remain the same. Just looking at times over a range of distances, This isn't even hair splitting, it's splitting the atom of a molecule.
On times alone, these guys are in a dead heat with eachother. Many will argue that Farah has a World class marathon time too which would give him the edge for now as range counts in who is a better runner so either Kejelcha has to run even faster at the shorter distances or blow away Mo's Marathon time to seperate himself significantly enough to say he is a better runner even on times alone and disregarding medals.
