Regex:
[^\s]+(\s+[^\s]+)*
The regular expression [^\s]+(\s+[^\s]+)* can be interpreted as follows:
[^\s]+: Matches one or more characters that are not whitespace.(\s+[^\s]+)*: Matches zero or more sequences of one or more whitespace characters followed by one or more non-whitespace characters.
Explanation
Characters which aren't whitespaces are allowed in general. If there are one or more whitespaces, they must be surrounded by non-whitespace characters.
