Mumbai has already taught us something useful.
Having a venue is not the same as having the right venue.
The previous chapter was held at a farm on the outskirts of Mumbai. The race happened, but the setting did not create the chapter we or the community wanted. So we are starting again.
There are easier ways to solve this. Find enough land. Measure 6.706 kilometres. Put up a corral. Ring a bell.
That would produce a backyard ultra.
It would not necessarily produce Mumbai.
The next venue has to do both. It needs a loop worth repeating through daylight and darkness, room for runners and crews, safe access, medical reach, permissions, parking and enough resilience to function for as long as the last runners decide to continue.
But it also needs identity.
A backyard runner becomes intimately familiar with very little geography. The same road. The same turn. The same tree. The same approach back to the corral. After enough hours, those ordinary things become the entire world.
We want Mumbai to have the right world before we invite runners into it.
So there is no invented terrain description here.
No convenient adjectives.
We will find the ground first.
Then we will let the race tell us what it is.
