* I think you'll be fine with 50000 downloads. Don't forget, vector tiles are cached. When people run they tend to take the same route or at least the same region. Hence the cache should be resolving lots of requests. Right now, while admittedly with the bug in online download for few days, during 6 days we had 3000 requests by Poor Maps GL users. @otsaloma, though, knows better with his stats of Poor Maps and tile downloads.
