Okay-- so here is my prediction.
Sadly, I think Hellen Obiri is injured, and Sharon Lokedi is going in. Kenya had a send-off ceremony for their Olympic Team. If you look at the pictures and videos, Hellen Obiri is the only athlete noticeably absent from the team processing. Even Kipyegon was there before her 1500 World Record, and US-based athletes like Ejore and Kurgat made the trip.
Lokedi is in all of the photos, alongside Jepchirchir and Kosgei. I find it odd that the alternate would do all of this (especially with one of the members absent).
If anybody knows anything, please share. I looked on Hellen's Instagram, and she hasn't posted anything about training or what not.
