Udon to Bangkok. How?

STWW, how long does google reckon it takes from Bruxelles to Udon by push bike?

[jackspratt]

The walking time doesn’t allow for breaks so it’s a modest speed of 4.88 kilometres per hour
It Should maybe be given as 103 hours.

You would be foolish to attempt that walk without first confirming whether your insurance covers you.

Google seems remarkably silent on the subject of cycling, though if you intend to actually push the bike it has an opinion.
Regrettably there are quite a few problems places along the way where you need to dodge bullets not viruses and if the delivery did arrive it would probably have spoiled along the way if the delivery boy didn’t drink it.
