Olamide davido tekno others for 2017 access bank lagos city marathon

I think there may be some confusion here.

The Access Bank Lagos City Marathon is a annual road running event held in Lagos, Nigeria, and it's not a music concert or a gathering of celebrities. The event is a competitive marathon that attracts professional and amateur runners from all over the world.

As such, it's unlikely that Olamide, Davido, Tekno, or any other musicians would be participating in the marathon. The event is focused on running and athletics, not music performances.

If you're looking for information on music events or concerts featuring these artists, I'd be happy to help you with that!
